I know a lot of us know this simple way but I see so many guys fighting to unload their boats when they are by themself. This way might not work good if there is alot of current but in slack water it works great for me.Also cant do this if you have a roller tralier. Before backing onto the ramp i tie the front rope onto the tralier tongue un-hook all straps and ready boat for lanuching. Make sure your rope is about 5 -10' longer than your tralier.Coil your rope up and lay it on the front deck of the boat.Back "slowly" into the water until boat floats then start pulling ahead "slowly" until slack is out of the rope and your tralier is just out of the water about 5'. Put truck in park set brake un-tie rope from tralier tongue and pull boat up to ramp. This is the most simplest way i have found and the quikest.
