the best thing about corecell with regards to this project is how well it takes to heat forming. Either buy yourself an old domestic oven from Craig's list or make a heating box ( for small projects these are often made with timber, fibreglass insulation and a couple of heat guns) and you will able to shape wide transverse runs of foam and do minimum fairing or gluing.

Corecell is probably the best foam on the market, however, it is banned in the F18 class, not worthwhile on a boat built with a chopper gun or inferior to nomex for high end builds. As a result we see very little of it in beach cat land.
