Dont just limit yourself to a "bass boat" design. Take a look at the numerous semi v's on the market as well. They ride very smooth and can fish rough water. Yamaha has their line and many companies build them as well as Tracker, Ranger, Aumacraft, etc.
We bought a semi V when we moved here and wife and I couldnt be happier. We like the idea of being in the boat when we fish instead of being on it.
I went with the largest HP motor the hull was rated for. We have the speed when we need it and the ability to cruise at 30 mph at 3-3,500 rpms when not in a hurry to maximize fuel consumption and be easier on the motor.
