Any suggestions or comments regarding an Autopilot for a 23' boat? I'm looking to add one to help me while trolling. It wouldcertainly make my wife happy.I do not expect one to maintain course while running in the gulf. The TR-1 Gladiator looks like a very good auto, but I'm not inclined to spend close to $4000.00 for one. I have noticed that Raymarine has a SmartPilot series of autopilots starting around $1000.00. Thanks for any comments or suggestions.
