What bottom coat and how to prep for Superior

[TurboTim]

This is my first sailboat and I will be slipping it the water this coming summer. What is a good bottom paint for lake Superior, specifically Bayfield area. It does have a bottom coat now and some of it is chipping though not as bad as some of the other boats I have had. Is it best to sand off the chipping areas or is there a good way to scrap it off.

You don't need a copper loaded bottom paint for fresh water, because there are no barnacles or mussels or jellybags. All that happens is that slime coats the bottom.

Chandleries sell a fresh water bottom paint. Use that or else just sand the bottom so the paint will stick and paint it with a gloss yacht enamel, and get a diver to clean the slime off maybe once a year.

In Lk Ontario at least in the last two marinas I kept a boat at CSC or VC17 are the most popular paints going by the wander around the yard in the spring survey.
For the most part fouling isn't an issue, don't think I've seen zebra mussles stuck to a hull, everything else yes!
I use CSC, pretty much just need a quick wipe down at the end of the season. Next season you can repaint the thin spots where it wears away after a light sanding.
