I've read here that the Tsunami changed names to Sceptre in '76 due to Tsunami Boats suit, but the hull design suit is news to me. Penn Yan made a tunnel cut-away hull v-drive boat in the '70s but I don't know about any legal connection. Any more info on that would be interesting... would certainly explain its rarity on the SeaCraft hull...
Nice copycat rig, Fred
keep the boat porn coming...
