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.

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!

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!
