My boat was kept for two years in salt water by the original owner, who painted the bottom with a copper-colored ablative bottom paint. I have trailer-sailed the boat for almost four years in fresh water, and the paint is now showing its age, besides making a big mess when washed with On and Off. Does anyone have any advice about how to remove the old ablative paint and what it should be replaced with? I was thinking of sanding, but the recent posts on gelcoat damage from sanding are making me rethink that and ask for help. Thanks, Rick M17 #633 Lynne L

Hi Rick, I have much the same. Old paint from PO, and now I trailer sail it. Considered removing it, but that is a lot of work with all the strakes to get around. The Admiral says forget it. It only looks like crap on the trailer. In the water who knows? So I am living with it...for a while longer. Was suggested to me that a pressure washer may take a lot of it down, then maybe I would get into stripper, sanding etc. Would love it to be just bare gel coat, but I am sure that once it is stripped, it will need "something". Maybe a hard 2 part finish? Bill Makin' Time M17 #622 On Wed, Apr 13, 2011 at 9:42 AM, Rick Davies <jdavies104@gmail.com> wrote:

I'm cleaning the bottom this week. I found that using a green Scotch pad and a bucket gets it clean enough to recoat. At least that's the advice I've been given by a number of local yards. I thought you had to get all the old ablative paint off first but they look at me like I'm nuts.

Sand down a bit of the ablative paint until you can see what's underneath it. Hopefully underneath there is a layer of paint, usually grey, that would be the epoxy barrier paint. If so, I'd just get as much of the ablative paint off as possible and recoat. If there's no barrier paint, I would seriously consider removing the ablative paint completely. I talked to an Interlux representative at our local West Marine that was having a big tent sale. He said that he recommends a light sanding of the gelcoat, just enough to give the barrier paint some bite. Apply 7mils thick of the 2000E and then use bottom ablative paint. I think the key here is whether the PO used a barrier expoxy primer. But here's another thought. I keep SeaFrog in a slip nearly all year round. I used to keep my NorSea 27 in the water year round. The PO on the NorSea did not use a barrier coating. The last time I hauled her out, she had over 250 blisters the size of a quarter. It didn't present a problem of it sinking but it looked ugly and obviously slowed her down. The question that I don't have an answer to is this. If you pull your boat out for the winter and the hull dries out completely, is the barrier paint necessary??

Hi Rick, I just got done removing hard bottom paint. Used a combination of strippers and sanding. The stripper I liked the best was Aqua strip. Worked pretty well but one needs patience. And once you are done scraping some sanding is required. You will curse the fabulous lapstrake while doing this. Since the paint is below the water line I have never been concerned about sanding the gel coat there, as it needs it to either be painted of barrier coated on the boats I have had. I keep my boats in a slip so I have made it a point to barrier coat them. If you dry sail the boat I would not think the barrier coat necessary. My 1975 M-17 definitely needed it as it had evidence of some blisters. My M-23 appears to have the gel coat below the water line stripped off and barrier coated. And I am adding more coats. If you know what paint was used you can overcoat with a compatible paint. Once painted I don't think it is really practical to strip and restore it to shiny gel coat. You may want to just put on a hard paint once you have removed what is there since you trailer sail so it does not smear when you wash. Practical Sailor had a great review of bottom paints a couple months back. Robbin On 4/13/2011 9:42 AM, Rick Davies wrote:

My M-17, # 232, 1977 had old bottom paint with lots of marine growth when I bought her. I spent $9 at the do-it-yourself car wash, and really only removed maybe 75% of the growth. Boat yards usually do the job with a 2,000 psi (or more) power washer, as soon as possible after pulling from the water. Then it was hand-sanded and re-coated with 3 coats of West Marine PCA, since it would be moored in cold mountain water maybe 5 months a year. After a year, it still looks good. I would suggest that you have a good boat yard do the first recoat. They are much better at sanding and surface prep than I am, as my attitude is BAD. Next time you know what coating was used, and can decide what to use next. Some can be applied over old coatings with minimal sanding. Some just build up until they are so thick that they must be taken back to bare hull. If you want something worth worrying about, its osmostic blistering. My M-17 has no blisters, but I think it may have an epoxy barrier coat as I see grey color if I sand into the hull finish. Once you get blisters, the remedy is about 6 months dry-out, followed by epoxy barrier coat, then fair and finish with anti-fouling paint. I had a San Juan 23 that I had to de-blister twice - ugh! On a new hull we used to sand lightly to take off the gloss, wipe with acetone to remove de-molding wax. There are better products available now, but we never had adhesion problems with anti-fouling paint. I've paid boat yards for bottom jobs, and done them myself. Not fun.

I have a bottom paint question. My '83 Lyle-Jerry 17 was naked on the bottom when I got her. ~:0) Never had anti fouling. I have mostly just moored her on the lake. Start of season I wash her up and give her a coat of wax. Plunk her down. Our lake a very warm and I swim a ton..so I just brush her down underwater now and again during the season. A very thin layer of algae grows but otherwise nothing that can be washed off easily. Any reason NOT to keep doing this? Tim In the Caribbean of Canada.
Thanks to all for the information and advice. Although hope springs eternal, I didn't think it was going to be easy, and I have to admit I like the idea of having a yard do at least the heavy lifting of preparing and recoating. Come to think of it, I also have a bad attitude to working on a lapstraked bottom in summer's heat, so I may have a yard do it all. Now all I have to do is find a good yard. Does anyone have experience with yards that do good work at reasonable prices in the DC/Annapolis area?

Yes, I happen to like the yard that my M-23 is at. Breezy Point Marina just south of Chesapeake Beach MD. Mike runs the place with help from one or two other guys. Also there is a independent Fusion Fibre at the yard that may be able to help. This is very much a do it yourself yard to the extent that you want to and very reasonable. It is probably on the minimalist side but I like that. I know that Dennis has/had his M-23 worked on at Tall Timbers on the Potomac and seemed very pleased with the work. They may have more crew at Tall Timbers. I do know from experience that stripping the hull is a lot of work. Robbin On 4/14/2011 9:12 AM, Rick Davies wrote:
