Just an idea..
How about letting epoxy treated marine ply be part of the test? This material has well known properties and have been used extensively in small catamarans. Perhaps not the best if you want to convince 'modern' beachcatsailors about stiffness, longitivity etc. tough..
The F-18 Blade (ref:
F-16 forum) was buildt in marine ply, and they added a lot of glass to achieve class minimum weight. So testing with marine ply is at least relevant.
Will your new hulls break if you are T-boned at speed? I bet the Royal Navy never performed that test

Since you have glass added to the plastic, will it be possible for amateurs to do repairs (unlike the usual thermoplastic) with epoxy and standard glass?
