I've read and heard several times that a rope, from trailer to the hitch on the vehicle, can be used to lower the trailer down the ramp far enough to float the boat without driving into the water.I launch my O'Day 192 on a fairly shallow ramp and have often had problems. With the vehicle's exhaust pipe just about under water, I usually have to have someone standing on the trailer tongue, pushing the bow of the boat to get it to slide off the bunks and into the water.I'd like to be able to launch it alone, but the procedure described above requires at least two people.Can anyone describe in detail or, better, show me how to launch with the aid of a tow rope?
