I just bought a new powerboat that was always trailered. I have a slip
and plan on leaving the boat in the water most of the season. I know
the bottom will have to be painted, but I was told it would need to be
sanded first. Is this right? I don't want to have to get the bottom
sanded if I don't have to.
It's a 1994 Bayliner Capri, if that makes a difference.
Thanks

Others here will probably have more information than I, but
let me give it a try...There are two reasons you might need to sand
the hull.

First is if the bottom paint that you want and/or need to
use is incompatible with the existing paint. In this case you have
to sand off all the old paint right down to bare. I suspect that you can
find a bottom paint that works over your old paint.

The other reason to sand is if the current paint is in bad
condition / flaking off. In that case you need to sand off
all of the loose existing paint. This doesn't mean sanding it
all off - just whatever is loose.

Interlux tends to have some good info on their site about all this, I think.
