The good news is that if you keep up with it, it is not such a big job. Tiny barnacles are much easier than 2 inches of growth! Another tool: waterproof headlamp: this allows you to see much better and still have 2 hands free. Find any issues? use a waterproof camera with flash (even a throw-away, but digital is better) and then analyze images blown up on your computer.
