San diego yards
First of all, if you use a professional diver to keep your boat clean, he can probably help you more that any of us. Ask his advice on your projects and consider his suggestions. If you don't use a diver, hire one to clean and check your boat just before the planned haul out. You'll be ready to start work as soon as she comes out of the water and save the $75-125 they want to charge you for the pressure wash.Boatyards. The two I've used, Kettenberg(Driscoll) or KohlerKraft on Shelter Island, both allow do it yourself work. Usually on weekends. Last time I went there you could power sand, but you had to completely skirt the vessel and use a scavenging device on the sander. For blister repair, I don't recomend using a grinder, way too much power for the job. I recommend a variable speed random orbital sander for the larger blisters and a Dremel tool or a hand chisel for the little ones. Regarding the two yards. Kohler was the most helpful, but it was my first time, so I needed help. They haul the boat out on a cradle/railway system whereas Kettenberg uses the more common lift and jackstand method. There are advantages to both, I guess, but I found it inconvenient to crawl around the cradle under the boat. Another thing, Kohler doesn't make money on lay days, they make money on the haul out, so they don't want their cradles out of service for any length of time. When I was hauled out, the yardmaster examined my boat and advised me on the work that needed to be done and recommended supplies I needed. Then I was told that I had to go back in the water on a specific time and date, because they had reserved my cradle for another customer. For that reason alone, I would not go back to Kohler. Kettenberg, on the other hand, simply charged me the $54/day until I finished. I did not seek any advice, but the lift operator was super helpful. He moved the jackstands and painted the areas under the pads for me. My next haul out, this spring, will be at Kettenberg. Now, with that being said, I recommend you go to the closest yard that will let you work on the boat yourself. Don't forget Newport Beach. But, don't they have a yard in Dana Point? If there's a lot of paint removal and blister repair, give yourself plenty of time for that and perhaps hire the yard to replace the thru hulls. Trust me when I tell you there's more work than meets the eye when you break out the sander. If you have a friend to help you things will go a lot faster. Don't hire any non-yard contracted workers, you'll be asking for trouble. Good luck.
