,My marina won't allow outside
workers to work on boats. It is a nice way to develop and maintain a
monopoly.

Do they have experts on the payroll for anything that might come up. Many
marinas have a bunch of min. wage bottom scrubbers that "learn" fiberglass
repair, electrical work, etc. on your boat.
