When I paid my slip fees at Jamestown Marine I asked about the lake icing over and was told that the lake has never frozen, due its depth (avgs 90'). If I should chose to pull her out and bring her home for some winter repair projects, would I have to refresh the anti-fouling bottom paint. I have hesitated to bring her home for that very reason. This summer, we went 39 days without raina nd I could have done a great deal of work had she been here instead of 2 1/2 hours away and sitting in 120' feet of water. Ever try to recover a screwdriver when you drop one over the side? I have been under the impression that bottom paint dry too much if kept out of the water for more than 30 days and a repaint would be in order. What is the truth of the matter?
"... bottom paint dry too much if kept out of the water for more than 30 days... "
It depends on the paint. Most ablatives don't care about sitting with extended 'dry time' (that's why I use them). Many 'conventional' bottom paints do have a period in which they will lose their effectiveness if out of the water.
At any rate, I wouldn't let bottom painting stop you from hauling out... sooner or later you'll have to do a paint job anyway. If the bottom is in good shape, it only takes a couple hours to clean and re-coat. If you're thinking of trailering and/or haulouts, I'd go ablative. Most ablatives will overcoat conventional paints if the bottom is in good condition.
Well, Clam, this bottom is one year old and consists of 3 coats of Interlux 3000, 1 coats of Interlux 2000 and 3 coats of Interlux Micron. We had to sand her down to the gel and fill too many blisters before we could paint her. In the West Marine catalog, it states that Micron, "Can be hauled and relaunched without loss of effectiveness". Does that mean that I can bring her home and over-winter her here and relaunch next spring with out sanding and adding a new coat of bottom paint?

Yes, Micron is an ablative and doesn't lose effectiveness out of the water. In my experience, it typically doesn't need sanding before recoat.. a pressure wash and a bit of action with a scrub brush on stubborn areas is usually all that's needed for prep.
With three good base coats in place I'd guess your paint is probably good for another season. This depends a bit on the level of fouling in your area and how often you scrub the bottom. If you are a racer and are scrubbing the bottom before every race it will reduce the lifespan of ablative paints.
When you haul out, check your bottom over and see if there's any thin spots or areas where growth is started. The leading edge of the keel, the rudder, and along the waterline are ususally the highest-wear areas. These areas are pretty easy to 'freshen up' with paint before re-launch.
Here on Humboldt Bay there is a near-tropical level of fouling in the summer so I usually pressure wash and put a fresh (single) coat of Micron on each spring. It takes a quart (thinned a bit) for the 'fresh-up' coat and an hour or so to roll it on. It reduces amount of bottom scrubbing later on. (kind of a pay me now or pay me later sort of thing). As I stated above, I pay some extra attention to the keel, rudder and waterline.
Thanks so much for another great response from the "Forum". Unless someone out there knows of a really good reason why I shouldn't haul her out, I think that I will do that soon. It will give me an opportunity to do the things that are difficult to get around to when the boat is 3 hours away. The other thing that makes it difficult to work on her is that when I get to the lake, I can't just work, I need to sail.
I don't believe depth is a factor involved in the lake freezing over. Lake Superior has a max depth of 1700 feet and has frozen completely over on a number of occasions.
As for bottom paint, try VC-17 the next time you repaint. Its practically maintenance free and easy to clean.
