How much effect will rain have on ( Pettit Hydrocoat ) ablative bottom paint if left on land.Will the rain wash/activate and wear away some of the bottom paint. Thanks Tug
 
Well, when Journey On is on the trailer and it rains, there's not much water that gets down there. That's one point, another thought is that I put on Micron CSC, another brand of ablative paint, and included the trim tabs. They made it through this wet winter with no signs of ablation.

So my answer is: not a problem, at least if you live in California. Don't know how snow affects that paint.

By the way, they're banning copper paint in Calif.

Sounds like it might be a good time to re-paint (before the ban.)

That, of course, would depend on the relative cost and effectiveness of the newer paint types compared to copper.

They'll probably still allow copper and maybe even tin based paints on merchant marine sea-going vessels. :sad

I'm not at all against environmentally friendly regulations, just would like to see some rationality involved.

Too often we, the recreational boaters, the under-represented minority and get regulated, and the big boys, represented by their lobbyists, get off free.

Joe. :teeth :thup
 
The problem with copper bottom paint is that recreational boats sit in marinas 80-90% of the time and leach copper into the water. This provides a concentrated dose of copper into nearshore waters adversely affecting fish and shellfish.

Big ships spend a large portion of their operating time offshore where the copper is spread thinly over a large area of open water.

Automobiles shed copper from their brake pads and contribute much more copper to the nearshore waters than boats. In Washington state, copper brake pads will be outlawed, but not for years. Copper bottom paint is also outlawed, but not till 2018, it think. Here in WA, our highway dept is building 'swales' (a wetland along the highway) to filter highway runoff.

In WA, there are now many boatyards that either do not allow copper bottom paint or are trying to switch their customers over to non-copper paint.

Non-copper bottom paint will be the way of the future. Now with a known deadline, paint companies will develop good non-copper paint if they want to stay in the boat bottom paint business. A company called Sea-Hawk already has such a paint. Its supposed to be good paint, but I personally am waiting for others to prove it.
 
Boris.thats good. I wanted to take down the shelter to get the direct drying affects of the wind and sun.Tug
