My boat, based on the upper reach of the Hamble, has been in the water continuously for going on two years now. I lift and scrub her approximately once in four months, which is the maximum life of the anodes. Her bottom has never looked all that bad, but the speed difference from four months of growth to freshly scrubbed is amazing, so I would be loath to scrub less often than that, even if my anodes lasted longer.
When I bought her, the bottom had just been done with some kind of eroding antifoul. I think the bottom might have been blasted off beforehand, because the bottom was very smooth and nice looking -- much better than the bottom of my old boat ever looked.
Now after five lifts & scrubs the antifoul still looks very good, very smooth, without any flaking or thin spots whatsoever. In fact I can't tell any difference in the appearance of the antifoul from two years ago when I bought the boat. Except the lead keel, where bits of antifoul are coming off, especially the leading edge, same with the bronze skeg.
Here is my question: It seems to me that it's simply about time to antifoul the boat. The previous boat lived in Florida and I would never dream of going two years without fresh antifoul. But these waters are different, with different growth, and much less problem with barnacles. If the antifoul looks so good, maybe I should let it go for a while longer? Maybe it's even harmful to build up unnecessary thickness? Maybe I should just sand and prime the keel where the lead is showing through, and antifoul that? Instead of the whole bottom.
What do you guys think?
I was just about to order 17.5 litres of Jotun Sea Queen, when I thought it might be wise to solicit some advice.
