Hello everyone,

It looks like I am going to be keeping my boat on the water and will have to bottom paint my boat. I will be keeping it some of the time out of the water though. Any suggestions on what is the best paint for it? Ideas on how much is a reasonable amount?

Thanks for your help!

By the way, I did a search and was pretty thoroughly confused. I have never had to bottom paint any of my boats, that's why I'm confused.

The March issue of <i>Practical Sailor</i> has an excellent article on bottom paint. And you're right-it is somewhat confusing. Here's a table for your area from the article:

I had a bottom job done about 6 months ago. They used Interlux VC Offshore. They also mixed equal parts of blue and black. The blue by itself wouldn't be my favorite color. I was told by the person that did the work (which was a friend of mine) that if I was ever going to trailer I wanted to use Offshore because it's very hard. I had a dozen gel blisters fixed and the bottom job done for a smooth grand. Yea, that hurt a little.

Piggybacking on this topic...

What would be the best bottom paint to use if you keep your boat on the trailer when not sailing? I have read that some paints don't like to be out in the air. I'm also concerned about the rubbing issue when sliding on and off the bunks. She will be sailing on a freshwater lake in Arizona.

Thanks and

If you don't plan on keeping the boat in fresh water for more than a couple of weeks at a time, you can probably get by without painting it at all. Just wipe off the bottom after the first week, and pull the boat out after the second week and scrub it off.

I'd love to have a slick bottom as you describe however there are unknown layers of an unknown type of bottom paint that were applied by the 2 POs. I wonder what the cost difference would be between a strip job with new bottom paint vs. a strip job with fresh gelcoat?

Hmmmm

I keep my boat in the water for about six months out of the year, keeping it on the trailer for the remaining six months. I use what the boatyard calls a "sloughing" or trailerable paint. I have done this for four seasons so far with excellent results. I'm not sure yet if I will need a new paint job this season. I examined it last week on the trailer and it still looks pretty good, however, I'm going to let someone with more knowledge advise me before I decide whether or not to put new paint on this season. (By the way, my boat stays in saltwater environment.)

RAULPOU,

We have a local fleet (#25) here in NE Florida. There are six of us here (until Tom is offically gone

who cruise together occasionally. If you would care to join us just give a shout. Chick-a-pea is just south of Julington Ck and there are two on Doctors Lake and one out of Julington and two at NAS. We'd be glad to have you along. I'm going to send you an email also.

There have been numerous discussions on bottom paint on this forum, but I can give you my experiences over the last several years keeping a WB in the water ... although it's fresh water.

I had the original paint job done by my dealer using Interlux Micron CSC (the paint they recommended). It didn't hold up ... I suspect due to poor surface preparation. Afer a year in the water, the paint was peeling off and could be removed with a putty knife.

The dealer made good on a new paint job ... but it still cost me the paint ... which isn't cheap and he marks it up more. The 1st repainting held up very well, and after two+ years, I had it redone. The cost of the repaint including haulout, pressure wash bottom, sand, paint (2 gals), and relaunch was around $1400. I think this is on the high side, but there's no competition here to help lower prices.

So ..... the lesson learned here is:

Make sure the surface prep is done well and done right. All wax from the fiberglass mold and added by finishing must be removed. Lightly sanding the surface is recommended, but a no-sand primer/sealer could be used on a new boat.

If I had it to do over again, I'd probably go with VC17. Everyone I've talked to about bottom paint loves it -- especially those doing their own work. It has a big advantage of drying very fast. This allows you to pull the boat out, touch up the paint, and relaunch in the same day. When painting, you can put on several coats the same day. You can just hose off whatever slime manages to stick to the Teflon surface.

My WB in the water has been holding up well, though. It's been in about 6-7 years now and still looked very good on the last haulout.
