I often think it would be a service to have a Dock Cam so I could check on the boat safety wise, particularly in winter, but on the other hand some may have privacy concerns--not that they would have a case--legally in NY at least, there is no expectation of privacy on a dock, and this is not a government camera,--but they are paying customers and they may object to someone not associated with the yard itself taking constant pictures.
The face of the miscreant is of no interest to me. OTOH I think this stuff very interesting for a tech view.
