I've had so many of the same questions, engine, speed, price... My favorites:
Idiot: You must do a lot of fishing in that thing?
Me: No, its never had a fishing pole in it and never will as long as I own it.
Idiot: Then why do you have those rod holders? (referring to my racks on the tower)
Idiot: Whats that wooden thing on the back?
Me: Its antique high performance hydrofoil. It allows the boat to plane out faster.
Idiot: Really? I wonder if I can get one of those on my Bayliner, but I would get a newer one...
