As a matter of fact, since here we go again, when a boat is bottom painted initially you have to splash the boat within 30 days. After a season in the water the paint should still keep its copper content even through the winter. And By the way, No it is not a "rumor through massive boating supply chains" We tell people this because I get customers in the fall who want to paint there boat for next year, we advise them not to because the paint looses its antifouling properties when left out of the water without being splashed. Oh and by the way, you can call interlux, petit, or us paint to quote me on that!
Anywho I was just trying to help but was once again bad mouthed and criticized by the know it alls among us.

Sorry to interrupt
