I have always trailer sailed but now I am planing on getting a slip and leaving her in the water. I need to bottom paint and I am looking for "how to info" and "lesson learned" for jacking the boat off the trailer.

Two methods from past discussions

Long detailed discussions of this somewhere in the archives, we need some kind of index for subject matter. Anyway, one method involves hoisting each end by some means, like a scaffold or barn stringer, until the trailer is rolled out and the boat blocked up. The other involves jacking up the whole trailer and boat, blocking the boat up, and then letting the trailer down. Or combinations of these, depending on what facilities are available. Would help to know what kind and size of boat you are talking about.

Another way

Guy I talked to the other day says he paints everything he can with it on the trailer, and lets it dry. Then he floats it, shifting it to show the unpainted areas and covering them. He says to just slap the paint on. Uses a paint roller. Says it goes fast and dries fast. Biggest problem I have found is figuring out what bottom paint to use for a trailer-sailer. Most of the bottom paints degrade quickly when out of the water. A few don't. Be sure to get one of those.

Dry docked with old bottom paint

Hi, I'm keeping my boat on the trailer, but the previous owner had bottom paint put on at some point. It looks like heck now, and I plan to repaint it sometime in the not so distant future. Question is, since I don't realy need the anti-slime guard, could I, should I consider some other form of paint - one that won't rub off as fast as the bottom paint seems to do? Thanks! Kevin PS. I was planning to do the paint everything I could, and then refloat and not pull it all the way in thing. Also considered just trying to jack up one end at a time using some kind of wooden block system to spread the force out.

To ablate or not to ablate?

I think it's easiest to refloat and shift the boat aft on the trailer to paint what wasn't exposed. Kevin, As for using another form of paint: Remember that the anti-fouling protects against everything that grows in the water including all critters and plants. It wears away on purpose to keep a fresh coat of unfriendly material exposed to the marine life. Unless you're hauling out and washing down after every use, you are likely exposed to more than just slime. If you do haul out every day then a good marine epoxy paint and wax job is all you may need. The great thing about anti-fouling paint is it doesn't have to be scraped away. It just ablates away and we replace it every year. It only costs so much because of that damn little anchor on the can.

Thanks - Going to try

Found an article that outlined getting the boat from the bunks by: 1. Lowering the tongue of the trailer, which raises the stern, and block it up. 2. Then raise the tongue all the way up and block the forward end and lower the tongue. Lowering the boat back to the trailer is the reverse. In this case I’ll bottom paint everything I can first. Raise her and leave the trailer where it is and just put a tarp over it. Paint fast and with the level caution that it could fall at any time.

Sanding and Painting with a Pole

Dave - I lower the trailer front and rear for bottom painting and felt really uncomfortable sanding and painting under the boat. A friend suggested I use a sanding block on a pole (normally used for sanding drywall joints) and a paint roller on a pole. I tried that last spring, it worked great and I didn't have to crawl under the boat at all.
