It's getting a little cold these days to go and check the bottom of the boat. Some areas of the country like Washington State going after recreational boaters and preventing them from using copper based anti fouling paint. Why? Because they can. Meanwhile, they don't say boo to the commercial vessels in their waters. But there is some good news:

"Multi-seasonal barnacle (Balanus improvisus) protection achieved by trace amounts of a macrocyclic lactone (ivermectin) included in rosin-based coatings"

A research paper of the stuff can be found here. Even better news is that Ivermectin is already very available for boaters and anyone else that may want to make their own antifouling paint. More states may follow with the copper ban. But, if they come for my Gam Pro 6 in 1 Paint Scraper they will have to pry it out of my (hopefully not dead) hands.
