Antifouling….what type?

[Merkinbrumsky]

Just finished shovelling another foot and a half of snow out of the driveway, trying to trick my brain into thinking spring is close…lol. Bottom needs doing on my voyager 28. Question for the group. I believe it’s a copper based Antifouling on there currently, at least that was what the surveyor put in his report when I purchased the boat. It does not rub off easily like an ablative so I believe his assessment to be correct. Overall the bottom is in decent shape. Was planning on a light sanding then a redo. I have used interlux on previous boats but it’s been a while since I did one myself.
What brand/type would you guys recommend for fresh water use going over the old copper stuff. Boat is in Georgian bay. Even though the old stuff is worn, not much algae growth, just a few zebra mussels around the running gear and transom at haul out. Come on spring.

The last few years we had a boats on the bay we just went with the power wash done well on haul out then just did around the waterline and transom , one quart.....just the interlux black powerboat stuff......never found the need to do the entire bottom like in other places and after a few years or so the power washing cleans of a good portion of the paint stuck to the bottom.

Yep we have cleaned snow more this year than in the past 4 combined....even had it down south on the gulf...

I’m guess you mean the interlux bottomkote? That’s what I was thinking as well.

We just got back from 2 weeks in the DR.what a punch in the face all this snow is. 2 reasons Trump won’t annex Canada…Jan & Feb..,lol.

Yeh thats the stuff, just could not for life of me remember the name. Nothing fancy and it works up there, as there really isn't much fouling if you use your boat a bit. I used to paint it on day before launch.

Interlux's Fiberglass Bottomkote formulation changed a couple of years ago. Bottomkote-CA is the replacement product available in Canada now. Keep in mind that this is no longer a hard shelled paint like the old formulation but is an ablative type that washes off with use. Also keep in mind that this is a one season formulation like the previous one. Once the boat is out of the water for a while, the coating looses it's effectiveness, might still look good but doesn't do much to fight growth. For a multi-season coating, you'll need to go with something else like Micron CSC-CA at a higher price point.
