I still plan to install a remote control inside my autopilot. The transmitter is water proof, and I always thought if I fell off, I could theoretically turn the boat. It would be more likely to just make it stop so it doesn't sail away, rather than make it sail back toward you.Along these lines it occurs to me that it would be a cool thing if you had a gizmo clipped to you that would send a signal to the autopilot to turn the boat around if you fell overboard. Does that exist? I realize that turning around a sailboat is not as simple as just turning the wheel but you get the general idea.
Having experienced our first MOB or actually it was a WOB, the biggest mistake we had was not having any lines on the back of the boat. Normally we have lines coiled up tied the cleats, which can easily be thrown in to rescue someone. SO along those lines, if you were sailing alone, you could always just drag a line out the back of your boat. assuming the conditions were moderate, you'd likely be able to grab it before the boat got away. Of course in heavy conditions, you want to be tied in.
