It
sounds like
Scream&Fly, BoatMad, or
BoatFreaks,

but it's probably one of many I visited yesterday at
http://www.sharkeymarine.com/. (There's a whole bunch under "Forum Links").
BTW: NY's
Sharkeymarine (speedboat construction) was a big player in killing off New Jersey's loud-boat-exhaust law. (And other proposed New Jersey speedboat restrictions I won't be addressing
here).
