How often to you scrape or clean the hull while "down there"? When we had
the Navigator in Jupiter, FL for a couple of years we had a diver do in the
water hull cleaning once a month.

With a good ablative paint a light sponging off is all that is needed
except around the waterline. We hire a diver every 3 months or so,
mostly to check/change the zincs.
