Both ablative and hard paints are equally effective at repelling barnacles. But the OP doesn't have a choice about what type of anti fouling paint to use. Because he plans to keep the boat out of the water for 6 months at a stretch and hard paints cannot withstand extended periods exposed to air, he must use an ablative paint.

Thought Petit Vivid was a multi season hard paint.

It's a "hybrid" paint that has some attributes of both ablatives and hard paints. In practice, in the water, it's as easily removed as any ablative, maybe more easily. According to Pettit, it can be used successfully on dry-sailed boats.

Re: First time bottom painting

And the ablative paint will hold up in salt water as well?

Well, it would help to know what specific product you had in mind, but yes, most paints are designed for use in saltwater.

I just painted the bottom of my MacGregor 25 last week and I used the other half of the gallon of and still have a little left over. Two quarts is more than enough. As for how many coats..........well, one is enough. When it wears off put another one on. Each coat will last a year.
When cleaning the bottom in mid season, use a plaster knife (10") to scrape off slime and such. Do not scrub the bottom.

Take it from someone who cleans boat bottoms for a living- this is bad advice. Clean your hull when it is lightly fouled and use carpet or a white Doodlebug pad. Never use anything hard or edged on your anti fouling paint unless necessary to remove hard growth.

Think of it as a cheat sheet for those of us who don't know what we're doing.
