Just get one of those cigarett boats and modify it for fishing. They ll do 80mps or more. I always wanted to see one of those with riggers hagging off it. I figure 3 or 4 driftsocks should get you down to good trolling speed. Or just put a kick on it so you dont have to run the twin 400hp engines. You could fish any were on the lake in a day with out trailoring it, you could just race to were the good fishing is at 80mph. Probly need some heavy duty brackets on the transducers so they dont rip off the back at 85mph. Just think the the thing will be a chick magnet after your done fishing for the day, and no one will crowd you fishing because they would get and ear ache from the noise from the exhaust.
