I would like to thank everyone that responded. I never thought that adding a item to help me safely return home or help with the auto helm to keep my boat true on course, would make me a non boater. I know that I can dock my boat, and sometime not even hit anything, but I spend most of my boating miles offshore, fishing, don't need a bow Thruster out there. But I go to all most a different dock after or during each trip. The last time i wish I had one, I was coming back from p town ,cape cod,(about 100 mile south of home port) and due to ruff weather need fuel to finish the trip home. So coming into a river ,tide ripping out, new and unfamiliar to the area, well that was one of the times I wish I had a Thruster. still not sure for it yet or no, but I guess I could spend the money on better things fishing.[:-eyebrows] quick question does the great lake have tides?
