I bought a used Hunter 19-2. All the lines where dry rotted. Especially the line going to the centerboard (keel). The best way to replace that center board line is to take the boat somewhere that has the proper equipment to lift the boat with a crane, and straps, because the boat has to be about 4 feet off the ground. I really couldn't figure out a safe way to jack up the boat in my driveway. Once the boat is high enough, It is a piece of cake to change out the line. There is a 3/4 inch bolt inside the boat that holds the centerboard assembly on. Take out that bolt, and the whole center board assembly should come out the bottom of the boat. It takes two people. One to take out the bolt inside the boat, and another to catch the centerboard assembly on the bottom of the boat. My centerboard assembly was stuck in the boat, and did not drop when I took out the bolt. So what I did was screw in a longer 3/4 inch bolt, about 6" long, and tap on the head of that bolt with a hammer, until the centerboard assembly dropped out the bottom. Once the centerboard assembly drops out, it is easy to change out the line. Once you change out the line, push the center board assembly back in the boat, and tighten up the 3/4 inch bolt, and you are done. Then just lower the boat back on the trailer. Piece of cake! You can either pay somebody to do the whole job, which probably won't be cheap, or you can ask them to raise the boat off the ground, while you and a friend drop the centerboard and do all the work, which is what I did. I fix air conditioners for a living. The place I went to needed his A/C fixed at his house. So I fixed his A/C, and he let me use his crane. I just I had to pay for the replacement line, so I got off cheap. I also replaced all the lines on the mast while I was there. I just have to fix a couple of more things on the boat, before the boat is lake ready, but they are minor.
