Re: Bottom paint how bad is it?
If the paint is losing adhesion to the gelcoat, which tends to happen when you get a thick buildup of hard non-ablative paint, that does unfortunately mean that the best fix is to remove all the paint, and start again.
The other plan would be to sand it all down, including the bare patches, removing any obviously loose paint, and then paint.
Which route you take would depend on your cost tolerance, level of perfectionism, how long you plan to keep the boat, and so on.
A strip tends to be rather expensive. The best way is a chemical strip. It's rather labour intensive. I think to have my 31ft boat done, cost me about $3500.
