Painted the bottom with one gallon of Rust-Oleum bottom paint (47.5% copper). Since Nellie will be hauled in October there's no need to do a full bottom job now. (Update: The Rust-Oleum was not a good bottom paint; lots of hard growth--10 May 2014).
Tried again to fix the slow leak in the dink. The process was (1) rough sand the area; (2) wipe it down with tolulene; (3) put three layers of 2-part adhesive on both the patch and the area to be covered; (4) apply the patch and rub it hard into place with a wrench. Letting the patch sit for 24 hours before blowing the dink up.
Had a hard time replacing the 4"x6" Divers Dream zinc. Its nuts were completely encrusted with marine growth. Both studs turned. Got the zinc off but will have to remove the studs and re-bed them before putting the new zinc on.
A year since it was installed the heat exchanger's pencil zinc was completely gone. Need to check it every six months.
