A cold molded boat is a boat with a laminated wood or fiberglass hull. The wood is cut into thin strips about 1/8" thick. these are then bent over frames on a diagonal to get the hull shape. Subsequent layers are added with epoxy resin, on the diagonal running the opposite way so they cross. Essentially the hull becomes a single thick piece of plywood. There is a fiberglass material made in strips called C-flex that is also used to build a boat the same way.

You don't need a mold, so it is good for a one off. However you don't get a molded smooth gelcoat, so finishing the hull is very labor intensive.
Ah thank you..great info..so its pretty much the same as cold molded then?

In all due respect, there is some confusion here. A cold molded boat can be any combination of wood venners or wood veneers over strip planking. There is no one recipe for a cold molded skin. If you putn a core of foam beween cold molded skins then I would call that a "composite" boat. That is a very good way to build.

As for longevity: My cold molded NIGHT RUNNER just won it's class and was First Overall in the Swiftsure Race this weeekend against some very fast and fancy competition.

NIGHT RUNNER is 35 yers old!

I should correct myself. NIGHT RUNNER is only 32 years old.
But it has been around Cape Horn and it has plenty of miles on it.

LOL, well, she's practically new! My strip planked ketch (designed by WD Knott) is 43 years old, but I can't imagine she ever won any races. Her design very traditional (enlarged from the 36' gaff schooner Aries). But she's also tight and sound.

Maestro,

You are the client. You have no budget restraints, within reason. What is your choice of hull material ? Don't go all exotic on me.

Now Fuzzballl is the client and fuzzball has no budget restraints. I really do like the idea of aluminium but ending up with a hull that looks as pretty as NightRunner would probably sway me to cold moulded.
