Here's How To Do It
Carl, I have a 23 and just finished redoing the bottom job; all by myself! I will try to put this in some easy steps. 1. West Marine was right, it is a huge mess and also expensive. The first thing you want to do is remove any barnacles(if there are any) with a putty blade. Plastic or metal is fine what ever works best for you. I had to use a hammer and chisel to get the oysters off my wing keel. 2. I prefer no electricity because power sanders and drills with sanding pads can quickly sand too deep into the gelcoat. So if you don't mind bending over backwards this will work great.Also, make sure to wear a painter's suit($10 at West Marine, a mask, and a pair of goggles. If the paint is bubbling or pealing a green scouring pad works great.They come with handles and various materials and textures(also can be found at West) Next experiment with sandpaper to find the right grade and start sanding. 3.Just in case your centerboard is metal and you sanded that far use osfo to treat ther metal.4. So now after you have finished sanding take a damp towel and clean up all the paint dust leftover on the boat. You may want to use something to prep the surface like acetone. It will depend on the paint you use. 5. Go to the store and get some antifouling paint. MAKE sure it is at least 75% copper. This will last alot longer as far as barnacles go. Get some rollers and a couple of brushes and start painting. 6. You want to make sure that you put at least two coats(I put 3) for the first six inches down from the water line. Two coats for the whole bottom is even better. Let it cure for about 24-48 hours and then put your boat back in the water. I may have left out some details that you might have trouble with (brands, boat jacks, etc) Email me if you have any questions liv2sail@angelfire.com Tony
