RE bottom job
Need a little more info, what are your intentions, new paint or just clean and put back in the water? If you are just looking to clean the bottom you can either take a soft brush and do it in the water depending on where you sail and the water temp/quality. Depending on the size boat, if its trailerable, when you haul take the boat to a car wash and pressure wash the growth off the boat. If its a larger boat then the yard where you haul would probably have a washer you could use or would do it for you. Trust me, you don't want to wait until that stuff drys before you try to get it off. jb
