I have watched guys launching and retrieving their boat alone and getting pretty wet while doing it. A friend of mine taught me a method that works well 90% of the time. In all the years that I have launched and retrieved I have never seen anyone else use this method.
Get a piece of rope about 25' long. Put a snap hook for your bow ring on one end and a 6" loop on the other.
Launch: Coil your rope and lay it on your front deck in a place where it can uncoil easily.
After backing down the ramp unhook your boat from the trailer and snap one end of your rope on the bow ring and put the loop over the winch upright on your trailer.
Back the trailer in the water and let the boat float off the trailer until the slack from the rope is gone. Slowly pull the trailer out of the water, the boat will follow you to the ramp.
Retrieving: You have to have side guides on your trailer for this to work. Back your trailer in the water where you can get to your winch without getting wet. Unless the angle of the ramp is really shallow you can usually get your boat started on the trailer. Push your boat out parallel to your trailer and guide it back on with the rope. If you can't reach the bow ring on the boat because it is not on far enough, pull your winch strap out a foot, put a couple wraps of your rope around the hook and you can walk the boat right unto the trailer repeating this a couple of times.
I have used this method when I am alone on both my Polar Kraft 168SC that goes 2000 lb loaded and my Alumacraft 1648 which may go 500 lbs.
The only time it does not work is in strong current or strong wind.
