Re: [bolger] Re: Construction Methods for Trailer Sailing
I built a 26' plywood on frame modified Pacific Dory. The bottom and
chine seams were fiberglassed the rest was just painted. The boat was
fished in Norton Sound AK, living on a trailer in the winter in
temperatures down to -50 F (-45 C). It was used commercially sometimes
packing Three tons of fish, twenty years after it was built, it was
still being used. It never leaked except when I forgot to put the drain
plug in.

Some plywoods tend to "check" and the grain raises up through the
paint. If you cover the outside with glass cloth the grain will not
show through the paint, and it will stand up to weather better.
Which books have you studied? Do you have any or Dynamite Payson's?
He is sort of the guru of instant boat building. His book and
catalogue are must haves.

Where in Finland do you live? There is a very famous Finnish
Bolgersita called "Martti the Finn". He build the very first Micro!
He is an expert on adhesives and such from Helsinki I believe and

Plywood and wood framing is the cheapest and if you tape the outside
seams with glass tape and use good exterior grade paint, a boat will
last for years sitting most of the time on a trailer. The greatest
threat is rainwater that might get into the interior. So you need a
good cover if left outside.
Some plywoods tend to "check" and the grain raises up through the
paint. If you cover the outside with glass cloth the grain will not
show through the paint, and it will stand up to weather better.

> Plywood!If you don't want a boxy boat, the glued lapstrake with plywood plan
works well. Bolger has used it for the lap Chebacco, for example.

As I sit here in the land of ten-thousand frozen lakes, much of my
spare time this winter has been spent beginning my education about
the world of small (under twenty feet) homemade boats. Setting aside
the issue of the skill required to produce such a vessel, which of
the construction methods (carvel, lapstrake, plywood, etc.) is most
suitable for trailer sailing? In particular which method is most
tolerant of being in the water one or two days a week and spending

Everyone has opinions; here are mine.
The problem with a drysailed wooden boat is that wood is not a stable material--it expands and contracts as it absorbs or loses water content. This expansion /contraction is very powerful and is capable of breaking glue lines if big pieces of wood are involved.
The four solutions are to build with with pieces of wood which are too small to expand enough to break a glue line (plywoo/-coldmolding, or strip construction), to thoroughly encapsulate the wood in fiberglass (stripper canoes and wood cored fiberglass are examples), a construction approach which allows the planking to move (natural wood lapstrake), or the use of some material between double planking.
Trailing aboat shakes it and, over time, the rivets holding lapstake planks together get loose. Most successful homemade trailer sailers are plywood, strip, or cold molded.
