Bob of Oklahoma City, You wrote in your respones to Dick that "After the last outting the boat is resting back off the nose rubber bumper about 4 inches and that is probably the problem with the weight shift". I had that problem for years, but then I made a few brackets to move the front frame of the trailer (the part that holds the rubber bumper) forward about 4 inches. I only put my boat in in the spring and pull it out in the fall. It's 100 miles from my house to the slip where we keep the boat, so I do like to have the boat located properly on the trailer. I don't think it's a matter of the boat slipping back, I believe that it is the angle of the trailer on the ramp relative to the roller under the bow of the boat. When the boat is pulled out of the water, the stern rotates down and pulls the bow out of the "V" bumper at the bow. I acutally made some new clamps to hold the frame with the "V" bumper. Using this does take a little time to loosen the clamps and move the frame, but it is worth it for my piece of mind, plus the trailer tracks better with the boat in the proper position. If you are intrested, send me an e-mail and I will send you a photo of the clamps. I will tell you in advance that my trailer isn't pretty. Aldo e-mail aadjcamacci@panetwork.com
