How's Your Bottom Doing These Days ?

I’m on season 6 with my bottom paint that the previous owner applied. I wish I would have written the brand down when he told me.
Probably worth hiring a private dick to track him down and get his story when you think of the cost of a full haul out to bottom paint every other year if your NEW bottom paint doesn't have the longevity of the last painting.

We keep our boat in the Everett Marina which is brackish water. It's not uncommon to get a thin layer of ice on top of the water in the winter. Our boat sits now coated with micron 66. When we haul the boat, the marina requires that the marina do the pressure washing over a water handling system for environmental reasons. When they do, it generally takes most of the bottom paint off or at least a large amount of it. Therefore each time I haul I repaint. The longest I have gone is 3 years and at that point the zincs were falling off. Barney goes on the prop we're slowing us down, and the shaft had barnacles but of course that's a little concern. I think I could get more life out of my bottom paint if it weren't for the high pressure of the pressure washing system. Last time I pulled the boat out it had only been in the water two years but the problem was I had a broken shaft strut and needed to pull it out for that purpose. I did have a diver change my zincs last year and I think I'll hire him again to change them this year and inspect. We are not allowed to clean alebative paint in the water in Washington.

Thanks Ken. I think that's where the major portion of my Micron CSC was going to with the pressure washing each year. The pressure wash water (say that quickly three times) under the boat was bright blue. The CSC only lasted two years until the black warning coat was showing through. The current WM bottom coat I'm using seems more resistant to the pressure washing. Wash water under the boat has light traces of blue.

Does anyone move their boat from salt water to fresh water? I'm close to Seattle and was thinking if I moved my boat into fresh water maybe that would kill the saltwater growth but don't know how long that would take.

The simple answer is yes. You will kill saltwater growing bottom critters in fresh water environment. Not sure how long it will take. I suspect how many saltwater creatures / growth you are carrying on your bottom would be a factor. One question pops into my thinking. Some of these creatures are quite adaptive. Would you be providing an opportunity for an evolutionary change.

The other problem is even if they are dead, it doesn't clean you bottom. Dead does not mean gone. Cleaning the bottom is removing growth. Not exactly related to alive or dead.

Finally, I'm not getting any growth at all on the bottom of our boat. I guess that's because she's high and dry, in storage. She wouldn't be, but I can't find a summer slip I can afford around here. lol
I've either tried or talked to folks who have used every antifouling paint available these days, and found them all lacking in their basic function: antifouling.

Sorry I'm late to the party. We repaint the bottom every two years at Granville Island. Ashamed to admit I don't ask what brand/type the bottom paint is, I just pay the bill. This cadence seems to be about right.
