I had my 30' race-boat's bottom cleaned every week starting in August in Newport, RI. That's when the water starts to get pretty warm. Prior to that I had it done every two weeks. Just a quick wipe with a towel keeps the Pettit Vivid nice and clean. No prop to worry about.
Now that I have the C&C, I'm avidly reading the solutions to barnacles here, and leaning toward the Pettit Zinc spray. This has been an excellent thread.
