If your boat is hauled out, you’re about to get a full arm workout. This is the "no mercy" zone. Let the hull dry until the barnacles look chalky and dead—usually a day in the sun works wonders.
Now, put on some heavy gloves. Those sharp little shells will slice your fingers open with zero warning. I’m serious; I still have a scar from the one I call “Kevin.” Use a long-handled scraper to save your back.
Scrape parallel to the hull, not into it. Think of it like shaving a very stubborn, crusty giant. Once the big chunks are off, hit it with the pressure washer to blast away the leftover “barnacle dust.” That stuff gets everywhere, including your hair.
