Something about the Fountain INXS... It's one of the first canopy boats I ever saw and the lines on it are just awesome.
Any of the old Cig 20's, without the crazy big LipShip fairing.... The production #1 boat (cig 19) comes to mind, it's the Black one with Yellow interior.
The Don Q boat, Dirty Laundry, and a bunch of others also top my favorites from the good 'ol days.
