Paint for below waterline trailer sailer?

[MillingManDan]

I've finished above the waterline of my Hunter 490 and given the bottom a couple of coats of metallic primer. The boat will be used in lakes and possibly creeks next year, but unlikely to be in the water longer than a day. What finish can anyone suggest? Most paints are for above the waterline and blister if left submerged. Antifoul may not be suitable for my needs either. Can I just leave the primer? Is that an option?

When I was doing my 490 I was unable to find anything which was OK for continuous immersion except (a) something by Jotun which cost a bomb and came in a minimum quantity of 25 litres (b) antifouling. So I went (b) and used some Trilux hard antifouling which I had knocking around. That was purely for appearance - I am sure she'd have been fine with her Gelshield showing.

My Drascombe, which has replaced the 490 for fresh water fun, has the remains of some eroding antifouling on her, which makes a real mess when I haul out each year. Someday I'll get it soda blasted off and Trilux that too.

Trilux? I'll take a look.

I used anti corrosive high build zinc phosphate red oxide on my hull.I was doing the keels with it anyway and had some over,just put it on with a roller ,and it looks like antifoul when dried.Not expensive.

Jumbleduck, how did you route your job sheets back to the cockpit? There's a nice big ridge that runs along the top of the cabin (about an inch tall) that makes the bullseye's useless as the sheets would surely just chafe ?

There should be a track along that ridge with a sliding eye on it. The originals I had were scruffy so I replaced them with 20mm Barton track and these

and cam cleats on the plinths provided. Final effect:

Excellent. Yes those are still there though the cams need replacing. I can just about see your mast base is different to mine?

Sorry, I keep forgetting to take pictures. Looking through what I have ...

 

[MillingManDan]

Thanks Jumbleduck. Yours looks very different to mine. I wonder why?

I suspect mine may be a fabrication made after the original was damaged. Any chance of a piccie of yours?

How do you post pics? I'm logged in on my phone and it doesn't look like there's an option
