I don't own a FB but have piloted one (AND I stayed at a Holiday Inn Express last night
). Hopefully you'll get a owner to pipe in here and give you the real lowdown.
A couple things I noticed when Bob & Joel let me take their flatback/diver for a spin at the get together last year were that the flatback really handles differently than a conventional V hull boat: (Captflatback, Bob and Joel agreed on this as we were discussing it)
1) can "bow" steer whenever "it" wants to - can freak you out they say.
2) never really jumps out of the water to plane, just keeps going faster and faster to max - almost like a displacement hull but different. Kinda separating the water as it goes by but up on top.
3) as Scott said, the back can slide out on a turn and I didn't think I turned that sharp but obviously I did.
4) can get in pretty skinny water
5) the windows are a neat addition - great to keep kids busy while on the boat. I guess it's supposed to be a baitwell. Maybe the windows let the bait feel at home?
