how to make a boat of thermocol?
You wouldn't 'build' a boat out of thermocol, rather you could use thermocol as a 'core' which is sandwiched by the composite of your choice. I recommend reading up a little on sandwich construction but it is optimum if you want a strong and light, but bulky boat. Think boston whaler, surfboard. You can also use balsa strips as a core, personally I prefer it.
I'm with Peter.it's core material.cedar is also good. I'm sure you meant it as a core all along, albeit unintentionally. As soon as you coat it with polyester or vinylester or epoxy it becomes sunstrate rather than surface.as a core in particular you would drape some cloth over it as well. So.to the how to.make a male mold or blank ver it in 6mil vapour barrier so you don't accidentally bond to it and mount your thermocol.lay your glass cloth on it and coat. When you have enough built up on the outside and it has cured, pop the hull off the blank and flip it over and glass the inside over simplified, but that's the idea. At any rate.good luck with your project. ps.I'm interested in where that stuff can be bought too if you care to email me. thx. DM
