I currently have my boat on a yacht club dock, deep water. I have to pull my boat up about 10 inches, and drag it over the edge, which is metal and wood. I've been laying down carpet, and using some pulleys, but any other ideas? I don't like scraping the bottom every time I pull it out, and I am old and weak! I can't do anything permanent, and it has to be cheap! I'm going to sail today before the wicked cold heads down to Texas...so sad.
