The smaller builders here in Au are gearing up or already have geared up for prepreg carbon boats..
They use low temp uni prepreg which is comparable in cost or a little higher that some glass products.. (from memory $20 AuD a square meter 150 gm uni?) So two crossed layers +45/-45 for skins a little overkill but..) for the outer skin and a third layer of kevlar or glass for impact areas..

They use glass/vynl molds and simple wooden "ovens" with heater bars to "cook" to 100C.. Basically a box wich fits over the mold and the coils turned on for a set time.. With a thermo swicth to control the temp..

However the guys need to learn to vac a mold for good results..
