Pretty certain that is a Ross and if so I never did ask him what it was based on, sort of knocked around in the mid to late 80's had a bit of flex in it though, he did I believe an earlier one and then a later one
he advertised it in Dave's powerboat mag which incarnation of the mag though I'm not sure
the boat was featured with his misses on-board, in later years he has purchased or ran those Animal ribs that are ripped off a Revenger and featured them at the boat show in Soufamton some years back that was on again this weekend, perhaps Ross was their today
PS ... I will say when I knew him he was a real nice guy
