How about letting epoxy treated marine ply be part of the test
Thats a good idea, I have heard it said that this is more impact resistant than a normal GRP layup. So what is a normal layup for epoxy treated marine ply.
Will your new hulls break if you are T-boned at speed?
I would be happy to supply the hulls to be T-boned if someone wants to volenteer a boat to do the T boning

We are told it can be repaired but have not tried it yet.
