Years ago I had a 22' Whaler that I sold because it was good for Two people but not many more. The problem is that there's no where to store Fishing Equipment and no where to go to get out of the weather if it gets bad out. I just bought a 1998 25' Sportscraft and its a much better set up.
BUT, I'm having troubles with it too, see my post above. Have you ever had issues with your boat running good when its cold and then slowing down in 15-20 minutes?
