I'm about to start putting togeather a tug type boat designed to have a very low to the water profile. The intended purpose of this thing is to retrieve stranded float type airplanes from the middle of the lake. I don't need speed but I do need push power. I want to run it with a single prop using a 12 volt motor. I need both forward and reverse. Right now I plan to use a tugboat hull without any superstructure. A hull that's around 28" to 30" would be just about right. What do you suggest I use for a controller and motor? Any hull suggestions?
