Bottom Paint above the Waterline?

Hello, all you Brainiacs and Engineers! The only place on my Morgan 35 that grows stuff, weed, barnacles. is the water line. And, anywhere paint has worn off, bottom of keel, attachment points of the skegged rudder. I have Trinidad SR on the bottom, scant growth for 4 yrs that I have owned the boat. Don't know if it's the PTFE kind or the Irgarol. I have a friend that just had his boat painted and had the bottom paint extended above the waterline, about 4 inches. Seems like a good idea...Now he's not a lifer like you guys. What do you think? Will it stand up to being out of the water? It looks fine, I mean, not having a traditional strip of one or two colors, on the water line. So, let's hear Ya'. Thanks for your opinions. Kevin

On our Jeanneau 53 the antifouling is extended approximately three inches above the water line.
Has always been like that and never had any issues.
We use International Micron Extra. Dover color. Initially is is greyish but turn into a more greenish color after launch

Re: Bottom Paint above the Waterline?

Our present bottom paint and in fact the bottom paint of every boat I've ever owned has extended at least 3" above the waterline and as much as 8" on some. It keeps the waterline clean, if not growth free. No yellow stains or black lines and smudges at the waterline any more.

^^^^

We've owned boats with the boot stripe too low, and it's a PIA to keep clean.

Go up a few inches, saves a lot of trouble.

Re: Bottom Paint above the Waterline?

Most cruisers and anyone in a rolly moorage will have moved the bottom paint up beyond the designed waterline. Most people won't notice it unless it was moved it up a foot or so. Moved my water line up to the top of the boot stripe and painted on a new boot stripe above. Was a big improvement in boats appearance even though the floating waterline remained the same. No more slime on the boot top.

Re: Bottom Paint above the Waterline?

Thanks Folks, I figured I'd get an opinion here, and they are all positive. I don't think I've ever noticed bottom paint above the water line. Then again, I wasn't looking for it. So, above the water line it will be. Be nice not having to scrub that durned water line. I think that took longer than scrubing the slime off the bottom. Thanks again. Kevin
