Tough is 450 double bias each side of 5mm (or whatever ply thickness is recommended if it is a ply one) H80 (80 kgs / cubic metre) foam. Lightweight is 200 gsm cloth either side of same.
An uncompounded ply dinghy will be pretty easy to build using foam panels. A compounded one should be, but there may be some glitches if there is a lot of compounding.
I agree. That is the reason for doing a simple infusion dinghy. Both
to learn about infusion and to prove to my wife that this is not just
another hopeless project that will never be finished (can't imagine
why she thinks that might happen:-).
Unfortunately the only composite dinghy in the duckworks list is the
wave dancer, so I guess I will just have to make it up. John's site
has the basic dimensions and I can infer the others.
Does anyone have a view on the right sort of foam and fiber to use for
a dinghy? Those are the main bits missing from the site and I don't
really care if it is done "correctly" - as long as it floats for a
while it will meet my needs.
Thanks for your help.

have never done any resin infusion. I have made some 16" x24" foam
core panels just to test out resin infusion and different laminates.
I found this to be vary worthwhile even though I have built a number
of boats (plywood with epoxy glass sheathing). It would also help to
have a digital scale to weigh materials and test panels. You can make
a hand laminate for comparison and then do a vacum bag or infused
panel to test you setup and get the process down. This will help you
in deciding how to proceed with a a small boat project and give you
some experience working with fiberglass and foam core or other core

works. I would also like to get some polycore for comparison, does
anyone know of a source in the US ? I contacted Polycore corp. but
they said that they have no distributors in the US.
