I normally have not had much problem launching the boat. But this year at the Alton's ramp I had one heck of a error. and it was my fault. In preping the boat I removed the safety chain, and had to remove the front strap to do so. I forgot to put the strap back on....half way down the ramp, my son was driving the truck, I was in the boat. He had to realign the boat. It moved just a little, but no problem he started backing down and stopped about 6' short of the water. The boat did not stop. I was at that point triming up the outboard. Saved. I guess the boat weights about 4k but sure seemed heavier than that trying to retrailer it.
