Question though, what did you use the foam for in the pictures?
I sprayed the foam between the bulkheads and when it expanded and dried I cut it with a long knife while the bulkheads created the desired shape of the hull
I used this method in another project:

Hmmm...that interesting. I might have to try that sometime. It looks like you used the spray foam from a can - I wonder if using a stiffer mix-n-pour foam might give you a better and more consistent shape. I've tried using the spray foam in some other, but similar, situations and it seemed to suffer from a lack of dimensional stability.
Vinny, you don't need to vacuum bag the foam...in fact, if you put standard vacuum bag pressure on the regular blue foam, you'll crush it. You would only need to vacuum the fiberglass if you have some features in which the fiberglass does not conform to easily or if you are looking to get an extra bit of lightness and strength out of your laminate. You can easily lay up the hulls by hand once you have them shaped. There will be a bit of sanding and fairing involved after the fiberglass to get a smooth finish.
