Just did an Oceanis (because why pay someone else to have all the fun?).

Any osmosis won’t be apparent until you give it a good wash. You can appraise then.

It’s not overly difficult to repair even if there are a few blisters.

As has been stated, ablative needs the boat to be moving to be effective, so it can’t really sit still in the water for too long.

Totally agree on the boat needing to be sailed almost every weekend with ablative paint.

Five hundred pounds of paint on there

Full bottom job anything else You are just wasting your time

Try a carbide scraper before sanding. Will save a lot of time, money, and frustration. link

Looking at that bottom I would start with a 8” single action with 36grit and a flexible backing pad. It takes some skill and you can make a mess real fast.

Any sort of hardware store DA sander and cheap sand paper is going to make this take forever. If you can rent a mirka sander / vac and buy quality Mirka / 3m sanding pads it is worth it for the sake of getting the bottom job done before your next season is over.

Doesn't look that bad from here. Pressure wash and wet sand until it's pretty. If you don't have any blisters, paint

I'm on the fence. it's a freshwater boat. do I just paint or get self ablating paint. it will be out every season so I can just wash it off.

I always pay the extra on haul out to have it power washed when it is still wet so it doesn't wind up looking like this. Pictures look to me look like dried on algae, and that's no fun to get off. Best to get it when it's wet, but that ship has sailed. Might be a power wash will still work, not sure.

I just go vc17 over last year's vc17 and have for many years. Couple years ago I took most of it off, but it is real thin stuff. I took it off because it was looking a little crazy. It wasn't as hard/bad to take off as I thought it'd be. It was like a long weekend. A normal year I budget a couple evenings for sanding/prepping and half a day for painting.

It's my impression you only have to take last years off if you're doing something different this year.

Because race boat, I like to scuff it up with 320 to make it smooth before painting. Rumor has it my arch-nemesis goes down to 1500, but he also has a cadre of lackeys working for him. Looking at that keel, I'm not sure I'd get too worried on that boat.

The one year I skipped painting, the boat was noticeably slower toward the end of the year, and the marina guy who does the power washing admonished me for it, although I wasn't there on haul out day to see it.

You want real ablative bottom paint. Preferably on a smooth bottom.

Saltyoldseadog55@reddit

you want a freshwater paint. ablative works when the boat is moving. a hard paint is great to scrub when the boat lives at the dock.

i'd be pressure washing, sanding to gel coat, fixing blisters, fairing, a few coats of interprotect and a bottom paint.

you will want to address the keel tho. another has said rust from keel bolts. i'd go so far as to say you have an iron keel. clean and inspect. if you have to, take it down to the iron to remove any traces of rust. etch prime, fair, hibuild, interprotect, bottom paint.

check the torque on the keel bolts. if they are loose, you are going to have to drop the keel down a bit and rebed it. gflex is your friend there. if the keel bolts are rusty inside the cabin, they are compromised and may need replacing. SO much fun!

Ha! Yes, blister repair is so much fun.

I would strip it down back to the gelcoat. Then a layer of gelshield, followed by antifouling.

Stripping allows you to find any spots that need to be repaired. There are special tungsten scrapers to make it a little bit easier (life hack is to file down the corners of the blades so they can't dig in).

While you're doing this, take a good look at any throughhulls and replace if needed. Future self will thank you for the hard work as every haulout after is going to be a breeze.

Best to go with an ablative paint over a barrier coat. Vc17 is the preferred choice for most freshwater sailors.

if that waterline didn't give you a heads up while in the water. raise it up a couple inches. my nice thick waterline got halfway covered with bottom paint this spring and it made cleaning so much easier thorough the season. did it because I had to shave some muck off the waterline last season.

paint is fine. not a fan of the rust coming from the seam on your keel, though. check the bolts.
