My boat hadn’t been used much in all it’s four years. After the delivery I think she recorded about 60 miles on the log from early 2006 to late 2009. Not entirely surprising that she had something reminiscent of the Amazon rain forest clinging to her undersides.

I get the impression your suggesting that this coating is pretty effective in keeping fouling at bay by itself, if given a reasonable chance. So it may be that I should just give the prop a good polish and leave it at that. ¿Yes?
