Anke and I are building our next boat, and writing about it at ABargeInTheMaking.blogspot.com. Access to the net comes and goes, so I'll be writing in fits and spurts.

Please feel free to browse the archives, leave comments where you will and write, and I'll respond as I can.

Fair winds!

TriloBoat DIY: Owner Designed and Built


CERES by Erik Andrus

If it looks like a boat, it will pretty much behave like one.
-- Harold "Dynamite" Payson

TriloBoat DIY: Owner Designed and Built

The beauty of the TriloBoat approach is that pretty much anyone can design a decent boat, armed with nothing more than common sense, graph paper and a pencil. After that, pretty much anyone can build one.

That being said, it takes a dream, determination and resources - both internal and external - to pull it off.

The beauty of doing it all yourself is that you know every twist and turn of the decisions and compromises that led you to a vessel which exactly suits you. Or at least represents your own, best shot at it. In making it so, we become expert in our own vessel. Learn for the next round.

In this post, I'm featuring three Owner/Designers who started entirely from scratch to shape and finish their own creations. All three projects are linked in the right-hand side-bar... if you haven't been following them, I'd sure recommend looking through their archives!

I'm proud to have been a small part of each of these fine vessels. And pleased to have become friends with the fine folks behind them!


CERES

Erik Andrus is a farmer of organic rice on the Vermont shore of Lake Champlain. He had a vision of an engine-free cargo boat built and run by fellow farmers to carry organic produce down the Hudson to markets in New York City.

To that end, he designed and built CERES (images above and here) along the lines of a TAB (Triloboat Advanced Barge... profile and plan view curves very nearly match). The sprit yawl rig is traditional to Thames Barges. It is powerful, handy for short crew, can be quickly raised and lowered and the mains'l sprit doubles as a cargo boom.

CERES was built for a reasonable sum (around $20K, far less than estimates for the market equivalent for a commercial vessel). She served two successful seasons, with the Vermont Sail Freight Project (VSFP), whose profit margins handily paid for her construction.

Unfortunately, both CERES and the VSFP languish in the on-going search for that rare individual who can be skipper/entrepreneur/administrator.

Is that you? Contact VSFP, here.

AUTARKIA by Alan Jones

AUTARKIA is designed by Alan Jones and built with his wife, Lori. They plan to live aboard and cruise for extended periods on the waters of British Columbia.

Currently, they are detailing a very cozy interior, with luxurious room for two, and plenty for friends or family.

They're working toward a sailing rig that can be easily dropped for Fraser River bridges. One of the intriguing possibilities is Gundalow Rig, traditional on bargy hulls.

One of the things I enjoy about AUTARKIA is the number of simple, out-of-the-box solutions Alan comes up with. For example, his LED interior light mountings.

CORNCRAKE by David Reece

CORNCRAKE was designed by David Reece and built by the whole family to serve as a camper cruiser in sheltered waters of the East Coast (sailing out of virginia).

Note the effective use of paper, rather than any sophisticated CAD drawing. Most of the vessel's shape is determined in the profile drawing (side view).

I was especially happy to watch the two young girls participate, handling their jobs with competence and good humor. After experience like this, they'll not ever fear to work toward a goal. They'll know the feel of tools in hand, and the confidence to use them.

CORNCRAKE is currently put up, ashore, awaiting the family's return from an extended stay with family in Uruguay. When they return, she'll likely get junk rigged to replace the temporary, triangular sail she sports, now.

I mean, does this boat and crew look like fun, or what???

A DIY Portable Pram

Ken Simpson's CPB-1 Lightweight Folding Pram

I love to go a'wandering
Along the mountain track.
And as I go I love to sing,
My knapsack on my back.
- I'll spare you the Fol-de-roos!

A DIY Portable Pram

Many's the time we wish we could haul our dory up to a lake, but swoon at the prospect of lugging our dory uphill and over dale. Or wish for a second ride ashore. Or to float some firewood while we go exploring.

Ken Simpson, a retired engineer of some renown, has some solutions for us.

His site, Portable Boat Plans, offers a number of simple ways to get on the water quickly and have a lot of fun for little outlay. His designs tend toward the minimal, often sacrificing performance for economy and portability. But in the sizes he deals in, the sacrifice is small and the gains considerable.

His Lightweight Folding Prams, CPB-1 (free plans) and updated CPB-2016 (plans available for purchase), are of especial interest.

These two prams are built with coroplast, the corrugated plastic sheet material used for such things as political signs. It is relatively strong for its (light)weight, and, once the edges have been waterproofed, its corrugations trap air for positive buoyancy (it floats). Edges are waterproofed and joined with Scotch(TM) TOUGH (duct) Tape, making construction a snap. Minimal stiffening components are cobbled up from common hardware store items.

The result is a boat which weighs less than 20lbs and stows and carries like a portfolio!

Imagine a fleet of four of these, tucked away on board, ready to be used for kids and other company. As tow-boats for transporting a haul of groceries. As in, "Let's go climb to that mountain lake and paddle around!"

If we pull out all the stops, these might top out at around $100 each. By comparison, a packraft might cost around $600. 

That's a lot of bang for the buck!!
