Storm Tactics: Inshore

Carved handrail from S/V TANTRA

You can't stop the storm, so stop trying.
What you can do is calm yourself.
The storm will pass.

-- Timber Hawkeye

 

If you think it might be time to reef, it's time to reef!

- Sailor's Wisdom



Storm Tactics: Inshore

In life and sailing, storms overtake us.

Most often, if we pay attention, we have some warning before their onset. In rare cases, they pounce like a cat upon a mouse. We're the mouse, at least in scale. Unlike mice, we have a range of tools to meet the storm.

NOTE: When I say storm, I'm speaking of high winds in general. Our standing policy is to NOT be on the water in full storm conditions or worse. Despite this, we occasionally find ourselves caught by surprise.


Foundation

These are things I recommend which underlie a successful response to storm conditions:

  • Prior Knowledge... Knowledge and skills acquired ahead of crisis are priceless!

    Learn what you can before exposing yourself to storm...

  • Trained Crew... and train up all who sail with you.

  • Sound Vessel... Robust construction and maintenance, uncluttered decks, capable and easily reefed rig, good anchors with ample rode.

    Without these, any ship is at risk in any weather. When Storm comes with its long boots on, meet it with all head and hands on a stout deck!
 
 
Rules of Thumb

We use a small heap of rules-of-thumb to help us along our way:
  • Fail Safe vs. Fail Dangerous
  • Preserve Options
  • Layer Redundancies
  • Maintain Margins of Safety
  • Act Decisively
  • Develop Standard Operating Procedures
  • Develop Communication Protocols
  • An Ounce of Prevention is Worth a Pound of Cure
  • Get Out of the Wind, Stupid!
  • Avoid Smug
  • Manage Fear and Panic
I go into these at more length here.


Storm Tactics

  • Batten Down - Secure your gear inside and out, dog down hatches, dress for the weather and clip in. MOB (Man Over Board) in storm conditions is a very long shot, no matter how well drills have gone. Stay aboard!

    NOTE: Make sure your harness clips are short enough to keep you out of the water. The USCG warns that a person being towed in the water cannot clear their head to breath from their own bow wake from about 4 knots. We lost an acquaintance that way... his crew didn't know to round up and stop the vessel.
     
  • Reef Early - Reduce power before you are over-powered. Sail handling is easier and you'll be more comfortable and safer on deck.

  • Reach or Run for Shelter - Shelter ranges from protected coves, to the lee side of islands or points, to mere outcroppings that break wind and especially waves. Consider heading into the best shelter available before conditions deteriorate.

    It's important to note that, while wind can be unnerving, it is wind-driven water - weighing a ton per cubic yard/meter - which can toss your boat dangerously. Interruption of seas driven over a long fetch (open stretch to windward) will give your anchors the best chance of holding. Reefs, spits, and even thick kelp beds can provide effective shelter even as the wind whips over them.

  • Consider Quartering the Seas - Quartering (angling across them at about 45deg) gives a much easier ride in large or closely spaced waves, both for boat and crew. This generally means sailing close-hauled or broad reaching.

  • Consider Heaving-To, Sailing Backwards and/or Drag Devices - These are more often used offshore, but they have their place inshore. They help keep the bow up to wind and waves. You can adjust position to a degree by crabbing (backing or balancing sail to edge to port or starboard) without re-establishing full sailing trim.

  • Look Around and Enjoy the Storm - I mean, they are magnificent! As long as we're fool enough to be caught out in one, we may as well enjoy it.
 
It Was a Dark and Stormy Night

We've just completed a winter passage - under press of calendar obligations - that pretty well kicked our butts and tried our mettle. So all this is pretty fresh.

A mere 80ish nautical miles as the fish swims, we started out with winds which, unforecast, edged into gale force. Turns out that our main halyard had jumped a sheave and jammed... we could neither raise nor lower sail. 
 
Fortunately, it jammed in deep reef position... low gear, as it were.
 
Unfortunately, before we had reached a place to pull in, the wind first died to nothing, then turned foul. 

Fortunately, we had shelter behind us and ran for it.

Unfortunately, that shelter had its own katabatic blowing from it over the ebbing tide with river outflow... with our short sail we couldn't sail in.

Fortunately, after heaving-to in a lee all night, the wind returned in our favor, and we again sailed for our destination.

Unfortunately, the forecast called for gale with storm force gusts due before we could possibly arrive.

Fortunately, there was a small hook of shelter right at hand. We know it from years back and call it Whoa Nellie Nook (Nooks protect from North). It has a good lee, a protecting reef and good holding. So we sailed in, set anchor and got our sail (mostly) working again.

Unfortunately, our lee was SO good that a back-eddy of breeze blew us toward the beach as we slept (contrary to the wind that was howling about four boat-lengths from our position)... we whunkered down onto a rocky bottom as the tide ebbed.

Fortunately, the rocks were pretty round. We buffered with some wood cut ashore and lifted off again after several hours and re-anchored.

Unfortunately, the next morning's wind was blowing into our nook (the opposite was forecast).

Fortunately, there was a bit of sand off our protecting reef and we could kedge out and sail on.

...

That was two nights and three days of a five week passage. I won't subject you to the rest, but will merely note that we only got two full nights of good sleep in peace and quiet in all that time.

Looking back in appraisal, we find the following:
  • We need to ditch time-bound commitments, especially in spring, fall and winter.

    Each time we commit to some deadline (for a job, for instance) our decisions become influenced by calendar pressures. We're reluctant to back-track and give back hard-won miles. We trim our margins of safety and head out into smaller, less reliable windows. We push fair winds, tides and daylight hours, which can erode our rest and recovery. All together, we take on higher risks to honor our commitments.

  • We need to increase redundancies in some areas.

    For instance, we have a spare block with halyard on our mizzen, but haven't yet arranged one for the main. This turned out to be an ELE (Exctinction Level Event) on this trip (the jammed halyard could possibly have set off a lethal string of consequences).

  • We need to be more skeptical of weather forecasts in high wind seasons.

    Time and again, we sailed or anchored in conditions which proved contrary to the forecast. In one case, this could have cost us the boat (our sheltered anchorage became dangerously exposed in a 180deg mis-forecast blow).

    Area forecasts cover large areas, and 'predominant winds' is a squishy concept. Worse, we were mostly sailing between one weather system that reaches up into the Yukon (Canadian) interior and another that opens on the Gulf of Alaska. We're learning to look up and take the whole chain into consideration, rather than rely on more local forecasts. This is especially true when updating forecasts flip-flop in wind direction and/or strength.

    NOTE: To be fair, SE Alaska is made up of what we call geographical wonders (local places which alter, amplify or diminish weather patterns). Forecasting the weather - both for pros and amateurs - is notoriously difficult.

    Weather data collection points are few and far between, and are often in sheltered or compromised locations (e.g., at points between two weather systems or in towns whose location was selected for sheltered weather).

    Furthermore, a warming planet increases the discrepancies between models (based on historical data) and the real, emerging world. Winds are tending stronger and less predictable across the board. We need to increase our weather pessimism accordingly.

  • New technique for anchoring in marginal lees:

    Our problem at Whoa Nelly Nook was that, as the tide came in, our protecting reef covered and wrap-around waves sideswiped us badly. So we anchored in very close to the beach and ended up too close.

    The remedy for similar spots - now SOP - is to set two anchors aft against potential wind reversal and one or two high on the 'windward' shore. Tend the vessel with the tide to position close in the protected lee of wind and wave, then out as the tide falls and protecting reef uncovers.
     
  • We're approaching a decline in physical ability.

    This trip was physically demanding. Long hours on deck. Sails and (multiple) anchors up and down. Sculling long distances. Kedging. Swamped dory and recovery, and lots of bailing, often in rough conditions underway. Jury rigging gymnastics. And so on. Meanwhile, we're at the further end of middle age, and looking downslope.

    We're already planning a small, camper-cruiser for high mobility with less physical input. In coming years, we will be sailing WAYWARD less, and in less challenging windows. We are mulling adding an engine down the road (diesel/electric, possibly yawl-boat mount?).
*****
 
Sooo... we loved this trip for all its challenges. It kicked us hard, but there is no living like that at the edge in a gorgeous seascape of stormy wilderness. But all good things...

As Joan Baez sings the poem by Lord Byron:
 

So, we'll go no more a roving

  So late into the night,

Though the heart be still as loving,

  And the moon be still as bright.



For the sword outwears its sheath,

   And the soul wears out the breast,

And the heart must pause to breathe,

   And love itself have rest.



Though the night was made for loving,

  And the day returns too soon,

Yet we'll go no more a roving

  By the light of the moon.



Not there, yet, but we can see the storm ahead. Time to be thinking of shortening sail.

The View from Cold Mountain

 

Maddy's Camp 
from Cold Mountain, the movie


The mountains look in horror on the madness of the plains.

-- Roger Zelazny


You look at nature. Bird flies somewhere, picks up a seed, shits the seed out, plant grows. Bird's got a job, shit's got a job, seed's got a job. You got a job.

-- Maddy, from Cold Mountain by Charles Frazier



The View from Cold Mountain

Somewhere on the slopes of Cold Mountain, high above the madness of the plains, there lived from a wagon an old woman and her goats.

Or so goes a tale told of another time. Of another bout of madness.

A  refugee from that madness - dying by degrees from a grevious wound - is treated by her skill and kindness. He is set back on his road home with a chance to find and face what awaits him.

Had she lived below, among her fellows, that madness would have swept over her. Maybe she'd have been caught in it, and clamored for the blood of them others. Or maybe she'd have been overwhelmed by it, drowned in its flood or burned by its fire. Or maybe she would have kept her footing, surviving to see the bleak aftermath as the madness settled back to dark mutterings.

What did she feel, looking down from her height. Horror, certainly.

And pity, likely.

Were she younger, at least than she was, she might have felt a tug, too. To do something. To get in there and pull in some direction or another, shoulder-to-shoulder with others. To fight the good fight. To attempt change in whatever direction she felt was right.

But had she descended to the plains, she would have been swept by its madness. The good she was able to do in her story was only possible because she had kept far from the madness of crowds. 

I think it's no small question... what to do in a time of madness?

*****

Picture a river, a canoe upon it and all of us packed in. 

There's supposed to be a waterfall up ahead... stands to reason, but no one has seen it. Some say it's a hoax. Some that it's still many miles on. Some say they can hear it. Some try to warn their fellow passengers.

All the while, the river flows ever faster.

But resources are running low in the canoe, and squabbling for control of them has led to blows. Holes are being punched through the hull, if you can believe it! Few have ears to hear, or time to look up from the fray.

Let's say you are one who hears the thunder of the falls.

Do you do what you can onboard? Do you leap overboard? Do you bother to swim for some kind of shore?

If you stay aboard, surely, you will end up over the falls.

If you leap overboard and do not swim, your journey is over before its time.

But if you leap and swim, you may be ashore to help another from the water.

*****

Leap and swim... this has been our choice. 

Not a moral or courageous choice, nor yet a coward's. Merely one that follows from how we view the sweep of recent history. And I'm talking since agriculture.

Our cold archipelago is our Cold Mountain. Our boat is our wagon. The flora and fauna of these lands and waters our life bearing goats. We are gaining in knowledge and skills to share. And we love it. 

While we know that our bank may too crumble - that we are yet imperiled by the cataract. At least from here we can hold out a hand to those who get themselves in reach.

Do you hear the falls?

(Sea)HorsePower and Square Motorsailing

 

Full and Half-By with Todd Allen


Gentlefolk do not sail to windward.

-- I'd swear it was Sir Francis Chichester


(Sea)HorsePower and Square Motorsailing

Many years ago, Phil Bolger observed that, for the average sailor, most if not all sailing is done off the wind, with the motor being used for windward work. Furthermore, as many must sail on a schedule, he felt a faster transit to and from cruising grounds with leisurely, fun sailing once there was a plus for most.

As such, he began to design many of his vessels around that premise.

By average, one is sometimes tempted to think it means sailors with any sense at'all.

Note that by off the wind, one means the 180deg half-circle from a beam reach (90deg to the wind on one side), through straight downwind (wind on the stern), to the other beam reach (90deg to the wind on the other side). That's a lot of degrees of freedom... a lot of sailing!

In contrast, sailing to windward only allows half that from a beam reach to close-hauled (45deg to the wind on one side) and same again on the other. Plus, you're heeled over, often bashing into waves and spray, and the wind feels strong and cold.

So, despite motors being largely beyond my ken, I'll nevertheless share some musings...


Hull Design

Hulls that move through the water (as opposed to climbing on top of it) displace water ahead, downward and to the sides and are called displacement hulls. And all that pushed-aside water has to return to fill the hole left behind by the moving boat.

Some consequences for displacement hulls:

  • Speed is proportional to Length (S/L ratio)... the longer a boat's Water Line Length (WLL), the faster it can travel.

  • S/L = 1.34 x √WLL = maximum speed aka hull speed

  • It takes exponentially more power to approach maximum speed

  • Additional length provides diminishing returns in speed (longer is faster, but shorter is more speed per foot of WLL)

In other words and once again, small is beautiful.

Sailing boats heel (lean over) when sailing to windward. When they do, a wide, square transom dips its lower, lee corner under the water and drags. So we raise it to minimize the effect. Problem is, displaced water now has to travel more abruptly back to fill the hole we leave behind, creating turbulence and drag. Part of the price we square boat sailors pay.

But if we motor to windward, we do it upright (heeling is negligible). Accordingly, we can ease the aft curves by lowering the transom to kiss the water. You can see this in the picture above, and also see how little disturbance it leaves as it sails upright downwind.

So consider a transom with lower edge at the upright WL.

Another design element becomes practically negligible when not sailing to windward... Lateral Resistance. This is resistance to sideways motion, provided by dagger-, lee- and center-boards, keels, chine runners, etc.. 

Skip LR and all its many hassles.


Rigs

The lion's share of rig complexity arises when sailing to windward. Sailing down and off the wind calls for little more than putting up and spreading a shaped sheet to catch the wind. Efficiency might be important, but for the average sailor, not likely. If we're going small, everything gets easier.

Here's what I'd look for in a rig:

  • Forward placement... Put the horse before the cart.
  • Easily mounted and stricken rig... When the wind is again' ya, take it down.
  • Easily handled... Why be fiddlin' while the sun burns?
  • Easily reefed... Just 'cuz we're loafing along doesn't mean the wind won't blow up!
  • Consider a free standing rig... No shrouds or stays to set up, take down or worry about in a jibe.

Quadrilateral sails (four-sided) spread a lot of sail on a short mast for easier setup and take-down.

Consider Ljungstrom Rig, which meets all of the above, and has infinite reefing, which can be dumbed down for smaller boats.


Mechanical Propulsion

I'm a fan of outboard motors over inboard for their ease of dis/mounting, lower installation complexities and non-perforation of the hull. Any fuel spills are relatively easily contained and reduce the risk of explosion. Many regulations for safe installation of inboards are avoided.

Options include electric, gas and propane (and natural gas)... each have their fans. Among electric motors, trolling motors are inexpensive and are designed for long run-times at lower speeds on a given charge.

Consider modest, outboard propulsion.

Remember that it takes exponentially more power to approach maximum speed, which in a displacement hull is in any case relatively low. This means you can run at some fraction of hull speed - say a half, two thirds or three quarters - with far less power input than for top speed.

Now, you hitch up a few horses (power is often measure in Horse Power or HP) and you can easily push a small load at low throttle, while sipping fuel (or Watts).

Consider backing down from top speed to radically extend your range.


Manual Propulsion

Me? I'd still carry a manual alternative to those finicky mechanisms. 

A sculling oar is simple and effective. An Atsushi Doi Power Fin is less simple, but powerful (could almost skip the motor). Oars are tried and true, though harder to handle. Even a paddle will get you somewhere.

Consider 'auxiliary' manual propulsion.


*****

I'm going to present this f'r'instance cobbled together from correspondence with Todd Allen. He writes [my emphases]...

I've built my second Triloboats style boat, thought you may be interested.

This one is a micro version, 10 ft long, 47 inches wide (to fit in my utility Trailer!). Birdwatcher cabin, rockered hull with a taste of PDR shape at the bow. Cabin is 6 ft long, lots of storage under the decks. I added Oar ports on this one which I really enjoy using, both for rowing and for ventilation at night. 

I brought the lower edge of the transom down as low as I could to maximize displacement for supplies and to give as much buoyancy as possible to the rear section to support the weight of the motor. I got lucky and it's about right! 

Can maintain 2 mph easily under oars in calms. 

I mainly motor with my 2.5 hp Yamaha 4 stroke (24+ mpg), but have a small downwind sail I deploy as often as possible, using the motor as my rudder (turned off of course).

[I checked back with him about that great mpg...]

24 miles per gallon is not a typo! I love this little Yamaha 2.5 four stroke, one of the best things I have ever bought. I run it at just above idle most of the time, and this gets me to my cruising speed of 3.5 knots quietly. At just over half throttle I can get up to 4.4 knots, but louder and bigger waves. Full throttle digs a bigger hole, no real speed increase. 

One thing I'll note is my offcenter spritsail rig. Even though I set my boats up primarily for motoring, I find I sail as much or more than my traditional sailboat cruising friends because my sail is so easily set. 

I usually keep it up and brailed, so if a favorable breeze comes up, I drop the brail and I'm sailing, takes 15 seconds. Same for brailing it when wind dies. The slot top cabin of course makes this possible.
Makes me chuckle that mine is often the first sail deployed. Also chuckled on the last trip when a sailing friend complained that it took him so long to catch me going downwind in a light breeze in his 17ft Siren!

And there ya have it.

Running Downwind: A Jibe in Time

Too much, too long, too late?


But at my back I always hear
Times winged chariot hurrying near:
And yonder all before us lye
Desarts of vast Eternity.

-- This and italicized quotes below from To His Coy Mistress by Andrew Marvell


Quality of life is preferable to mere quantity for the vast majority of us.

-- From Being Mortal by Atul Gawande



Running Downwind: A Jibe in Time

Was a time I was pretty much satisfied with putting one foot in front of the other.

You know... plod along the path of life in pursuit of the dream. Uphill all the way, with the peak somewhere well ahead. Vistas opening wide in all directions. And what hurry? There is world enough and time.

Somewhere in there, the 'peak' comes and goes. 

Now, I'm not one who believes in an apex of life. Rather, that the entire journey comprises our One Precious Life, and that be yum. But I do acknowledge that time's winged chariot is careening down a cul de sac. Windows of opportunity are edging toward closed. Somewhere not far ahead lie those Desarts of vast Eternity.

At a mere three score years, I yet see time's imprint more than feel it. But the next will likely see those strengths that have carried me thus far blunted and diminished.

Too many of our friends find themselves late in life aboard a vessel now too big to handle and/or maintan. Going or gone derelict, ship and master. The former content; the latter sad or bitter. Their life ended -as they see it - too much before the End.

Their main problem? They stuck with what they knew until they no longer had the wherewithal to transition to something within their diminishing reach.

So it's coming, and coming soon. What to do?

*****

Okay. What kind of platform for living do we need? Need as opposed to want.

It comes down to two things:  A comfy, dry, warm home, and mobility.

Each of our sailing homes has provided both of these in one salty package. But the day will come when moving the home will likely exceed prudence, if not capability.

Our current best thought is to sail WAYWARD as long as seems wise, then haul her ashore as a fixed base. She's easy to board, heat and maintain (especially if sailing trim is no longer required). What's more, she's our bird-in-the-hand.

For extended mobility, a small camper-cruiser which can be rowed, sailed and hauled with relative ease. The smaller the vessel, the higher the ratio of muscle to boat. 

We can enjoy it as an expedition vessel into relatively dangerous waters while our abilities remain. Later on, the judicious selection of weather windows and a gentle pace. 

And when that won't do, adieu.






*****

I don't often look in mirrors, and even more seldom do I look at my head from above.  So my self-image is of a head of thinning but definitely present hair. An illusion undisturbed by my loving partner.

A odd-angle encounter with our little, post-card size mirror on our boat, however, gave me a startling glimpse of the the rut time's chariot has left across my upper pate!  

Smiley Face - Looking Up - Men's Shirts - Whee! TV



So I leave you with this cautionary yarn...

A Cure for Baldness

An uncle of mine never allowed his hair to grow because he said that to keep it shaved prevented it from falling out... the sad moral came towards the end of his life, when he decided to give his locks their one fling, and nothing was left but baldness.

Off-Center Masts for Off-Center Sailors

Don't get more off-center than this Bolger BRICK, TETARD
Note that crew weight has more than compensated
for heeling moment.

One does not walk into the forest and accuse the trees of being off-center,

Nor visit the shore and call the waves imperfect.
-- from the Tao te Ching

Think off-center.
-- George Carlin


Off-Center Masts for Off-Center Sailors

When we were building ZOON (ex Bolger LONG MICRO), we stood the aft mast in place, off-center, to see how it stood. A visitor to the project took three wordless passes around, humming and clucking at such unusual features as the square sections and bow transom. Finally, he draws himself up with hands on hips and exclaims, "NO. That off-center mizzen is just too much."

But that off- center sail was perfect. Squared off across the stern, we could run down the off-wind quadrant in a gale of wind with balanced power and a clear view ahead.

Since then, every boat has had at least one mast off-center for one reason or another. Masts at the aft transom are offset to clear the rudder and sculling oar. Those at the companionway are offset to allow center-line openings which, in a knock-down, remain furthest from the water and least likely to flood.

We've never been able to observe a sailing difference between tacks in our larger, relatively heavy cruiser size vessels. We will wing out the offset sail to its near side when running... from there, they overlap the foresail less and behave much better. Otherwise, it appears a draw.

But this one time...

I wrote this account in a previous post:
A friend of ours had built a Bolger BRICK (shaped about as it sounds). He brought it out to Tenakee for a Mess-About. All day, he and his daughter sailed circles around the rest of us (including respected designs of similar size by Devlin, Hess and a TORO!).
Circles, in fact, barely describes the figure 8s and jaunts across the inlet and back while our fleet trudged along in comparison.

I was wowed by this and have mused lo these many years upon it. Now I venture a theory...

The BRICK has its mast stepped along one hull wall, and very near the bow. The crew is live ballast, but in practice needn't move much around (according to its skipper). When I first saw the arrangement, I felt sure it would capsize mast-side at the first gust. But no.

Here's my thinking, taking the BRICK pictured above as example:

On the port tack (wind blowing from port across the hull to the lee-side sail) it acts as a proa. Windward hull lift is opposed by crew weight.

On the starboard tack (wind blowing into the wind-side sail, then across the hull) it acts like a normal hull (center mast). Leeward hull depression is opposed by outboard displacement.

Setting the mast at a point of maximum beam, in effect, doubles the beam! That dinky li'l x4ft punt has the equivalent lever arm at the mast as our x8ft WAYWARD. Whether sailing as a 'double wide' monohull or proa, the righting arm is twice what one can expect with a centered mast.

With such a doubling, one can fly twice the sail area or sail a normal amount twice as aggressively (which appears to be the case).

Somethin' to ponder on!


Picture this mast position as center-line!

Fishin'

One of many approaches to Hobo ReelsIs that a KIRKLAND Whiskey Bottle cork capping the bottom???

I'm a-goin' fishin',
Yes I'm goin' fishin',
Baby goin' fishin' too!

-- From Fishin' Blues by Taj Mahal


Fishin'

I've got to say right off that I'm not a fool fer fishin'. In fact, if fish weren't an important part of our diet and livelihood, I'd never set a hook. Anke, on the other hand, you might say is 'avid'.

For me, I'm looking to maximize the efficiency and minimize the sport. To do as little harm as possible, both to those too small to keep and those whose life is taken for ours. To cultivate a spirit of humble gratitude for a fish's life. To console myself with the knowledge that they are fellow predators dancing in the web of life.

For many years, Anke and I have subsisted on smaller fish- rock cod, pink salmon, dolly varden (between a trout and salmon). Lacking refrigeration and unable to carry the weight of jarred fish, these are all we can eat while fresh. Now, however, we have the displacement and tools for jarring, and have our sights set on larger salmon, halibut and dogfish (a small shark).

But these still swim mostly in our future.

Our fishing rods and reels are accordingly very light. Usually the cheap-0 kid's reels. They live on deck, ready to hand, and last a few years. But they're seldom made for salt water and get cranky. And they tend to hang up on this and that at inopportune moments.

Recently, I stumbled across hobo reelsDIY, compact and effective.

Plastic container types offer near instant gratification and are very practical, since they take little or no modification and securely hold a lot of gear for any given size. Check out hobo reels made from PVC.

Wooden hobo reels - whether carved or turned on a lathe - are just plain beautiful. But first, a digression...
At a Renaissance Faire I was once enthralled by a fellow turning chair legs on a pole lathe. He used a living sapling bent over as a spring, sprung by depressing a foot plank. A line connecting the two turned around a pulley on the lathe, and as he worked the plank, spun the leg stock for shaping. 
Unfortunately, it was otherwise a more or less standard metal lathe and, they being generally large and heavy, I hung on to the pole idea but roundfiled the lathe.
Back to hobo reels... one of the vids shows a feller turning one on a home-made pole lathe! OOH... now we're talkin'. It was clear to see that I could dumb his full-feature lathe down to a mini lathe sized for the hobo reel. An hour of cobbling from materials on hand and this is the result:

Ever the Muse brings chaos in her wake!
A bungee has replaced the spring pole.

Stock is skewered between a fixed point (left) and an adjustable point (right).
Two turns around the stock and it rotates around the points.

Never having turned anything, I grabbed a rather funky piece of firewood to try it out. To my surprise, the result would have been a keeper if I'd used better material! On to HR2.0...

Go small, go simple, go fishin'!

A few preliminary tips and tricks...

  • I've found that a single hook (vs. a treble) at the end of a line is easy to stow. Lure and / or bobber can be loop tied (pass a bight of line through a hole and around the item to form a cow hitch) as desired. Hook can be set into holes drilled around the spool base, or stowed in storage cavities with its line pinned by the cap.
  • Braided line (vs. monofilament) seems to work well, is much easier to handle and has enough friction for loop ties.
  • Instead of carrying one or more bobbers, an eye-screw can attach any found bit of flotsam with enough buoyancy.
  • For a bobber, consider a stick which can be thrown much farther than a typical bobber, hook and lure can be cast from a (rodless) hand reel.
  • If using a container, consider one with a pronounced flare (like one end of a spool) toward the casting end. This helps lift clear of the wound line while casting, reducing friction.
  • throat gorge (spine of wood, bone or metal sharpened at both ends and attached from the middle) is far easier to improvise than a hook. A fish swallows the baited stick which then toggles sideways to set. Size for target fish.

Bilgin' the Barge? Reflecting on the Pond


Princess Tuvstarr gazing down into the dark waters of the forest tarn
By John Bauer


Swim out of your little pond.
-- Rumi


Bilgin' the Barge?  Reflecting on the Pond

After the first day's sail aboard our first boat - a shoal, flattish bottomed life-boat conversion - we happily went about preparing a special meal for our first night at anchor.

To our consternation, some of our stores, stowed low and outboard, were mysteriously soaked! We checked the bilge under the floorboards and were relieved to see our customary few inches of water between lead ballast bricks (as low as we could pump it)... so we weren't sinking. Some fluke?

No further problems until the next time we went sailing. With the same, soggy result.

Turns out that, as we heeled, that little bit of water all ran to and piled up the low corner, climbing above the far end of our lowest shelves. Some water-tight storage boxes did the trick, but it left a bad taste.

*****

So this is a general problem for flat bottomed boats, especially those with no rocker amidships. Not only does all that flat skim of water add up when concentrated, but when upright there is no sump (a low point which concentrates water for efficient pumping).

But do we really need or want a (wet) bilge at all?

The purpose of the bilge is to collect and contain water that makes it inboard from outboard (seeping planks, say, or leaky through-hull fittings). Or oil spills from the engine.

But there are considerable downsides:

Basically, a sailor with a wet bilge is living above a pond of... well... bilgewater. A pond is always moisturizing its environs and contributes to that dank, musty smell that many think of as boaty. Mildew and 'dry' rot fungi love the humidity. Wooden boat frames tend to rot near the standing waterline of the bilge. Most bugs die of dehydration, but not if there's a pond handy.

Bilges themselves smell better, nowadays, than in the days when raw sewage was among the fluids, but a 'sweet smelling' bilge remains rare enough to be noteworthy.

In flat-bottomed boats, a bilge must be created by raising the sole (floor you walk on) by at least several inches. Another way of putting it is that you must lower any given headroom the same amount.

Traditional construction approaches are sufficient to achieve a dry bilge. As Larry Pardey put it, would you rather pump or sweep your bilge? It requires careful building and installations, with consistent, proactive maintenance. But doable.

With modern gap-filling adhesives and milled materials, we can achieve that high bar with much greater ease. With no more skill than is required to pull the trigger of a caulk gun and spread with a paddle, we too can achieve a truly watertight hull. And preserve precious headroom!

*****

In our boats, we go without a bilge. Generally, the inside of the hull is either the surface we walk upon, or against which we stow gear and goods.

This means, of course, that if salt-water gets in, you know it right away, and it's something to be dealt with pronto! As I've written, girder furnishings help contain any leak and localize any soaking.

In all these years, we've only had salt water intrusion twice. A new mooring ring sliced through two sets of line and chafe gear in a squall, and ZOON was blown onto a rock which ground a two foot hole through her side and bottom.

A wet bilge wouldn't have helped in this case.

SLACKTIDE drug two anchors while lying unattended in a squall and spent a happy few hours fracturing a couple spots in her bottom planking, which then seeped.

A wet bilge would have made life a bit easier, but then, we may never have fixed it by patching the inboard face? We're lazy that way.

*****

Once again, each of us finds the path that suits us. Some may prefer to pump, some to sweep. Some might hedge their bets with a dry bilge on standby. Others remember the adage, a leaky boat never sinks (yer always pumpin' her!).

Keeps it interesting!





P.S.... One nifty, fail-safer solution is to build a 'step' sharpie or barge - essentially a wide, hollow, keel that can serve as a bilge in an otherwise flat bottomed hull. It only need be deep enough to do the job.

The drawing below gives the general idea... I couldn't find a pic of one applied to a flat bottomed vessel.

SIP RIP: Deciding Against a Ply / Foam / Ply Hull

Adding inboard layer of 1/4in ply
Next space to my right has fitted foam ready and waiting
Two areas to my right, the inboard face of the hull is exposed

This guy oughtta be wearing his ear protectors!

I think I'd better think it out again!
-- Fagin, from Oliver! lyrics by Lionel Bart

SIP RIP: Deciding Against a Ply/Foam/Ply Hull

A friend of ours built a shop with reclaimed Structural Insulated Panels (SIPs). It flew together, was obviously superbly insulated and was strong and stiff.

But commercial SIPs aren't typically geared for marine environments (though I wish they were). Custom orders are possible but too spendy for us. With tape n' glue construction, these would be the bomb. Sigh.

DIY ply/foam/ply adaptations seemed within our reach, and they were. We've now built two boats with two approaches, and both worked out (WAYWARD's example). But, looking back, we've (pretty much) decided not to do it again.

Insulation (R-value) is awesome and totally stopped condensation. Positive buoyancy is a benefit we hope never to call upon. But...

Here's a list of cons:
  • Framing is necessary, finicky and expensive.
  • Through-hulls need blocking (in advance or retro-fitted).
  • Installing foam and inner ply is time consuming and adds cost.
  • Voids (which can rot or mildew) are difficult to reliably avoid.
  • They can't be disassembled for inspection.
  • Foam takes away from interior volume.
  • Foam adds fire hazard with toxic smoke.
  • Foam is a pile of plastic waste that can never be "disposed of properly".
Framing deserves special note, and is what truly tips our scale.

Its purpose is to take fasteners for furnishings (vs. epoxy welding or tape n' glue which we prefer to avoid), tie the inner skin mechanically to the outer, join panels and seal edges (as around window cut-outs). It must be well-planned, precisely installed and devil take those who change their minds. Corners are particularly aggravating, and may need doubling up.

So what's our alternative?

We now lean toward two layers of ply, laminated (we like an LPC such as Gorilla Glue for this).

Condensation is much reduced by 1in of ply, and 1 1/4in (using one layer of 3/4in for accepting fasteners) takes it down to near none. While insulation is relatively low compared to foam, it's still adequate. Strength is high. Buoyancy is still positive, though reduced. It weighs a bit more. Cost is oddly about even (pound for pound, thinner ply is generally more expensive).

Best of all, interior framing is eliminated... you can fasten anywhere into the wall or drill right through it without blocking.

TriloBoats are intended to be quick and simple as possible. We've found that ply/foam/ply in the hull sides run against that grain. While the results are good (at least in the shorter term), we feel that the net benefit doesn't pay for the effort.

Should we build again (please O Great Spirit, NO!), we'll continue to use a SIP approach for the main deck but go to a solid wall hull.

So R.I.P., S.I.P.s.

Hunkered Down, Sorta

Peering over the berm near high tide


 Social distancing. I've been preparing for this moment all my life.
-- Emblazoned on a T-shirt


Hunkered Down, Sorta

For the last several weeks we've been hunkered down in one of our favorite spots.

It's a small tidal estuary, protected by a berm which has been thrown back by winter storms. We float for an hour or two as the tide floods and ebbs. The residents - including the bears - keep their distance as well.

We pulled in with the idea of seeing how the (COVID) 're-opening' will go. One of the peculiarities of this place is that, for all its remoteness, we have a decent cell signal. Thus, when we peer over our berm, our view is wider than usual.

It seems clear that we are nowhere near out of the woods.

No vaccine. The virus is now well-seeded, relative to those early months. Contact tracing and quarantine authority are inadequate. Global (and U.S.) case rates are rising at a 'flattened' but still exponential rate. Many, many Citizens of the World, I salute thee! But re-opening?? Early results don't look promising.

Meanwhile, we are knocking down a number of projects on and around WAYWARD.

Chief among them is paint, but as yet, we've had no day without at least some rain. We're working on a prototype Power Fin (Atsushi Doi concept dumbed down in our usual way... more to come on this). The new sails need to be grommeted and mounted. The rudder system needed some work (lacing just isn't standing up to WAYWARD's heavier forces... we're adding at least one gudgeon/pintle). Spring cleaning calls as summer begins.

You know... the usual.

So here's wishing all of you health and happiness and a happy Solstice!

Love,

Buddy Boating: Cruising in Contrast

Bristol Channel Cutter

Yeah, but you sail where no sane people go!-- Our Sailing Buddy

Buddy Boating: Cruising in Contrast



A dear friend lives aboard - and with his sweetheart sails - a Lyle Hess designed Bristol Channel Cutter (BCC). And we all went buddy boating for a bit.

Now, Lyle Hess cutters were my first nautical love. I fell hard through the writings of Lynn and Larry Pardey who sailed SERAFFYN engine-free around the world, back when the world was a wider place.

To me, these are the epitome of Curvy Dog. Fast, weatherly, seaworthy. And breathtakingly beautiful. Over a period of half a century, they have proven themselves outstanding cruiser / sailors.

Yet we ended up taking another road. Despite a general similarity of displacement, plan area and volume, our two boats represent near polar opposites. They take the high road; we take the low... and along the road, plenty of room for thought.

Where to start? Maybe at the beginning?

These cutters’ virtues make them difficult to build. Their fine waterlines, full bilges and firm buttocks… wineglass sections, tumblehome, sheer and sweeping keels… all add up to some serious boat wrightery. That comes at a cost in skill, time, effort, materials and outlay of filthy lucre.

Us? Box it up to go, please. Cheap, but with mucho bang-for-the-buck. Heavy on boat wrongery… let’s say we travel paths seldom trod.

Deep keels and a high proportion of ballast make Hess cutters fast. But shoal waters are only available if the tides run high. That heavy ballast takes away from what may be carried.

We skim the shoals and sit flat when the tide goes out. Without all that extra lead (we get our stability from the boxy shape) we carry literally a ton more books, tools and supplies (which means we can stay out for months if not years on end).

Sailing with the wind, we were the slightly faster boat (our waterline length is about 30ft to the other’s 28). We winced a bit at their pitching, yawing and rolling in the 3ft following sea… our ride is ‘shippy’ in comparison. Still, we were quite aware that if we’d been sailing into the wind, they’d smoke us. But they'd have to work for it (junk rig tacks with tiller over... no sheet handling).

As the wind dropped, we turned inshore… even less wind, but if we needed to scull, far less distance to anchor. They stayed further out (motor back-up), and reached our destination a bit ahead of us.

We skimmed into the shallows and dropped a pair of anchors, drying out between tides. The view of the the surrounding mountains was panormamic, and that of the tidal meadows (deer, bear, mustelidea and birds) was up close and intimate.

After the tide rose high enough to clear a shallow bar, they motored in and anchored in a favorite spot. Indeed, were concerned that it might be taken. It had just the right depth - not too deep for their all chain rode and manual windlass, yet deep enough to stay well afloat through all tides. They had protection from wind from any direction, at the expense of a view.

It doesn’t get any more reliable than that all chain rode. But I wondered if a second anchor with nylon / chain rode might not free up their preference for just-so anchor depth and all-round protection (to avoid having to re-anchor). Well… that pointy bow… it just doesn’t allow room for doing much more.

I suppose we might contrast our accommodations at this point…

The BCC is ingeniously but traditionally laid out. Her galley is, by our standards, cramped. Her salon is two facing benches… one has a fold-out double bunk outboard, and the other locker and bookshelves. The two together make up a space about 12ft long by a social 7ft (idle bunk and lockers squeeze the active space of their wider interior). Lighting comes from an overhead hatch and small portlights. Forward is a workshop / head, which one enters via a small gangway… well separated with full privacy and standing headroom under a raised hatch.

Our social space is 20ft x 8ft with a generous galley / workspace, bench seat opposite a dinette and a very generous double bunk / lounging space all of which are open to one another. Lighting comes via two overhead hatches, large galley windows and even larger windows running along the sitting / bunk areas. The side windows, especially, open the interior into the wider world for a sense of spaciousness. Our head is a composting double bucket system with little to no privacy (which can be arranged or found on deck if our guests are shy).

Poking around, their 7ft dinghy (which fits well on their cabin top) takes a few minutes to launch and retrieve. It does very well with one person, but drags a bit with two. Her beautifully fashioned oars really grab the water, but shoals - especially cobbly or rocky ones - threaten their exquisite varnish which is quite a chore to restore.

Towing our 16ft shorey costs as much as a knot to windward, but is ready to go any time, and rows fast and far, even when heavily loaded. Her oars are fugly; the simple ply blades are worn from years of grinding bottom and most of the paint has left them. But free for 20 years with no maintenance prorates pretty well.

*****

Looking across at one another’s boats and despite seeing the qualities of the other, we each, I think appreciated our own all the more.

Our boats very much reflect the way we roll, both on the front end - we choose a boat to match our purpose and style; and the follow on - our boats determine how we go forward.

Know thyself, my friends, and to thine own selves be true. Choose wisely!

COVID-19: Ozone Generators for Sterilization

Diagram from PrimaZone

COVID-19... Some dis-assembly is required.


 COVID-19: Ozone Generators and Sterilization


We've been using an ozone (O3) generator for several years, now, to sterilize our boat cabin and holds against various fungi including dry rot, mold and mildews. We also blow into a garbage bag to sterilize small items, now including masks, gloves and other PPE.

 << Our EnerZen unit costs about $85 as I write.

An advantage over UV sterilization is that it fills a space, where UV is line-of-sight and won't work in the 'shadow'.



While several studies suggest that ozone (O3) 'kills' COVID-19, this hasn't been fully established.

A word of caution... this type of generator sterilizes the space by elevating O3 concentrations to lethal levels for a short time. No People, Plants or Pets while working and until fully aired out. Don't even want to breathe a little of it. We amateurs should probably leave the building, even if you're only doing a single room within it.

Here's a quick article that hits the main points. And another in more depth.

There is another kind of ozone generator on the market which uses low levels of O3 to ionize particles to help purify air with people in the room. Some are being marketed as helping against CV19. These are not recommended by most medical authorities ever, and especially not now.

If breathed in, ozone irritates, inflames and even kills cells all along the respiratory tract. This makes the cells even more susceptible to virus and bacteria, and if infected, inflammation is a serious co factor for worse outcomes. 'Safe' levels for O3 can be understood as merely 'negligible damage' even when threat of infection is low.

Incidentally, ozone also clears away smells from such maritime nuisances as locker funk, diesel or gas, wet dog, bilge, etc..

Thinking of you all, especially in these somber times.



NOTE: Most hospitals have ozone generators for sterilizing operating and patient rooms. PPEs can be treated for re-use in room-sized batches. Even if it only reduces viral load, it is better than some of the desperate measures (such as paper bags between re-uses!). Please help spread the word your health care professionals.

NOTE: For sailors using ozone in the Spore Wars, be aware that ozone is extremely oxidizing, the heat-producing reaction behind spontaneous combustion. Be sure there are no oily rags lying about!

COVID-19: Why Nobody Likes Math


Double, double, toil and trouble!
-- Shakespeare


COVID-19: Why Nobody Likes Math
(Or at least, Mathematicians)

Um. The majority of people I speak with are busy making business-as-usual plans through summer.

COVID-19's global reach is doubling every 4 to 6 days resulting in explosive exponential growth. There's a lot of finicky issues in calculating these numbers... let's be optimistic and say it's only doubling every 10 days.

That is to say, the total number of people who have been infected with the virus doubles in every 10 day period. Let's roundly say that each month has three 10 day periods, so it will double three times every month. The total at the beginning of any month will grow by a multiple of 2... 4... 8 times by the end of that month.

As I write, today's global total is 300,000 who have been infected.

How many months ahead do you want to plan? Each month, the total grows by a factor of 8. Here's a convenient little planner:

  1. Mid-April ...              8 x 300,000   = 2,400,000
  2. Mid-May ...             64 x 300,000   = 19,000,000
  3. Mid-June ...           512 x 3000,000 = 153,600,000
  4. Mid-July ...         4,096 x 3000,000 = 1,228,800,000
  5. Mid-August ...   32,768 x 300,000   =  OOPS...
                                                              ...  exceeds human population.
  6.  
  7.  
  8.                          >>>  Here there be Monsters  <<<
  9.  
  10.  
  11.  
  12.  As I write, this is the earliest we might hope for a vaccine.

Things not cool today? So many months from now, the first number is how many times worse it will be at the present doubling rate. The math spotlights the urgency

If you can think in terms of doubling time (rather than days, weeks and months) it will help you with vital decisions.

*****

At the rates we used, the spread will peak sometime between four and five months out if it hasn't been flattened. That's the July? August? the President mentioned. 

While the CDC knows all this (their data, after all), they are coy about being specific. They urge, for example, that we have supplies on hand for "a period of time", or occasionally "two weeks". Yet stay-at-home orders implemented today are likely to be in place and tightening for months ahead.

China managed to flatten their curve and are seeing declining numbers of new cases. Whatever we might think of their politics, they moved relatively early and according to accepted epidemiological practice. In two months, they were able to locally flatten and reverse spread. Nevertheless, they may miss a case or two, or be re-infected from the rest of the world which has not taken strident measures to date. Then it's start over with the same 'draconian' measures.

Of course, this presently high doubling rate we're discussing won't sustain.

Social distance and travel restrictions will slow the rate of growth (won't eliminate it without unAmerican resolve). But these flattening measures also prolong the period of pandemic by spreading cases over time. Even if no measures are taken, the spread slows as a higher percentage of the population acquires immunity or dies.

Things won't turn on a dime. We are seeing measures ramp up late in the game, but early in the eventual spread. We hope to avoid the spike. At best, there will be tightening restrictions for months to come. Our best laid plans are all agley.

Meanwhile, the global economy is coming apart at the seams.


So provision up, batten down hatches and take a reef, me Hearties! 
Were in the storm, sure enough!!





The higher the dot, the slower the spread.
From Scientific American article


PS. Among the mitigation and travel restriction measures being implemented, travel by private vessel is being restricted in places around the globe. Even those of us who live aboard need to get where we want to be NOW, before rules and enforcement get around to our stretch of water!

COVID-19: Circle the Wagons

Important, but is it happening in time?
Treatment capacity lines seem optimistic, to me...
assumes healthcare is exceeded vs overwhelmed.

James gave the huffle of a snail in danger,
And nobody heard him at all.

-- A. A. Milne


COVID-19: Circling the Wagons

For those of you who don't know it, I've been huffling since the run up to Y2K about TEOTWAWKI - The End Of The World As We Know It.

Now I believe we're watching it unfold.

The basic factors are these
  • A fragile, Global Industrial Economy (GIE)... our tightly coupled, deeply indebted Complex Adaptive System (CAS).
  • A vast, overshot, human population which depends on a functional GIE for its livelihood.
  • Exponential spread of COVID-19 pandemic which will almost certainly overwhelm the healthcare system.
  • Failed containment and failing mitigation measures.
  • Exponential growth of associated problems.

Exponential growth of anything catches humans by surprise in almost every case. Windows of opportunity for meaningful action / preparation are snapping closed at a rate that's difficult for human beings to grasp intuitively.

NOTE: See here (~4 min vid... visceral impact of exponential growth) and here (~9min vid... exponential spread of COVID-19 vs flattening) to get a taste of the challenge.

David Korowicz lays out the general issues in his paper Trade-off (77 pages for the very interested) and specifically, pandemic based analysis in Catastrophic Shocks in Complex Socio-Economic Systems: A Pandemic Perspective (10 pages for the interested). Both are challenging reading, but, I believe, provide a foundation for viewing current events.

CAS's - such as the human body - have a range of stability. Within that range, they can be astoundingly resilient. But if events drive them beyond that range, a tipping point is reached and the whole system settles into a new equilibrium.

In the human body, an infection can lead to the loss of a critical function (breathing, say), and in a rapid cascade it collapses (and without rapid, correct intervention, dies). In a just-in-time economy, supply-chain interruptions block down-chain production and can rapidly paralyze the economy. In finance, disturbing the mountain of debt can bring currencies and institutions crashing down.

All of these are underway. [Or, for a less detailed and challenging glimpse of the problem, try this article.]

This is my long-winded way of saying that this is both serious and moving faster than we imagine.


 My Urgent Advice...

>>>  Get together with those you most love RIGHT NOW. Stay together for the duration.

>>>  Get together provisions RIGHT NOW (food, water, essential medicines, cooking/heating fuel) for a minimum of two weeks (CDC advice). Longer is better.

>>>  Make an isolation / infected plan and put it into action RIGHT NOW.

>>>  Don't panic, but GET MOVING.


Whether I'm right or wrong about larger consequences... even if the GIE manages to function beyond the crisis... even if your area has no known cases...  whether you are riding this out or hunkering down for trouble...

Containment and mitigation measures are shutting down travel and contact for unspecified periods. If flattening the curve is successful (our best chance), lockdowns will be in place for months, not weeks.

I say again, windows of opportunity are snapping closed.

Fair winds, health and happiness to all of us,

Dave and Anke




P.S. Here's some good advice from a guy who's been there.
