[Rhodes22-list] keel CB issue

[Andrew Collins]

Hi Mary Lou

The boat is in salt water on LI Sound, the anti-fouling is multi-season
(can't remember the brand) and did very well last year with just some slime
and a few barnacles present upon hauling. In looking at the pics again it
seems someone ground down the port side already so I will attempt the same
and make it symmetrical.
How often should one typically remove the CB cap and coat the inside of the
trunk? I suspect the answer is 'it varies' with conditions. The sound is
getting cleaner so I guess growth will only increase. Anyone out there on
salt water who does it every year?
Thanks
Andrew
