I got mine in Depron ( 6mm ). I laid 1/32 ply on the top for strenght. The bottom of sponsons has 1/32 ply and the bottom of tub is also 1/32 ply. I used thinned epoxy on the ply for waterproofing. I have no water rudder but made an airrudder and used piano wire from servo to airrudder.. I haven't had it out as the hot weather, storms and rain and now moss. Always something. I sand the depron and used latex house paint which they say doesn't eat foam, wait and see.
