Seamonkey,
I can relate. I typically fish in smaller or narrow hard-to-access lakes.
I decided against the Bass Boat thing and bought a used Grumman Sportboat and a trailer - like a square stern canoe.
I customized it for me and the electronics cost me far more than the boat.
I needed a remote deploying Ulterra because it is nearly impossible to climb forward to deploy trolling motor. It only comes in 24V so I added batteries.
I have a Humminbird Solix and a Honda engine. The Solix drives the motor (follows contours and lines I draw on the map). Next year I will put the Panoptix right next to me in back do I can aim it where I want to explore. The boat was the least expensive part.
