Good day. Here’s my 2 cents. I did keep my boat in a slip last year in Pensacola for about 9 months and we went out every couple of weeks. She had fresh bottom paint on before she went into the slip. I did not have any growth protection on the rudder or prop. I started to notice a decrease in speed over the next several months so I hauled her out in February to check out the bottom. The hull was nicely protected but barnacles had almost blocked the raw water intake. The white water line stripe was covered. The rudder and prop were covered. Bow thruster a mess. I made up my mind then to keep her on the trailer. It took hours and hours to get the barnacles off. I had purchased a product from a company called Marlin. Each can is 250 ml. One can is a metal primer you apply first. The second can is called VELOX PLUS. It’s an anti fouling paint for props and metallic parts. They aren’t cheap about $75 for both if I remember. Had the prop, rudder and water intake not been a mess my plan was to apply the products and continue using the slip but once I saw the growth I decided to keep her out. The two cans are still sealed in plastic. If your interested let me know. I’d like to know if they work.
Cheers,
Karl
