Real world Coppercoat motorboat review

"There is a good way to avoid this issue.... need to say that I have no interest whatsoever in the company selling the product - grab deep in your pocket once and you have no issue at least for the next 15 years. I had my 37 Windy treated with Coppercoat (the original stuff) and it works absolutely great. The boat can stay at the berth for 3 weeks easily with hardly no build up and once we go on plane the growth is wiped off. After the full summer (6 months of season in Denmark) I have lost only abt. 1 kt on the top speed - I can still push her 40 knots by September which is so close to top speed that I do not feel any difference at all. It is a brilliant product and I do not understand why this is not used more frequently by boat owners. You may pay a bigger bill now but you save the cost of antifouling every year (plus the time) and it works for many many years. When she gets out of water for the winter she is just washed down and the bottom is slightly green (the copper treatment is seen) and she is ready for next season. Someone says that every 5-7 years you may have to use a light sanding paper to refreshen the coppercoat but it still after three seasons remain to be seen. Can only recommend it."
