Re: Cleaning Hull in the water
Back in the 60's a device similar to that described by Brent was widely used, called a "boat bath" it was a plastic liner in your slip.
These are still around. Seem to me most widely used in Oz. Don't see them so much here in the States. And yes, the dirty little secret about their use is that they require regular additions of chlorine.
