CopperCoat is a hard wearing, densely copper-filled resin is protecting over 60,000 boats worldwide. A single treatment commonly provides a high level of protection for a decade or more. CopperCoat has been very generous in providing its excellent hull treatment product at a price that made it viable to my trip. The coating’s 10 year-plus lifespan gives me great confidence that Coralee will not need re-treating with an anti-foul product for the entity of the circumnavigation. A clean and smooth hull will be cutting days off some of the longer passages.
