When we were boating, this phenomena was referred to as the OARs - old anchorage residents. Simply means you got there earlier than anyone else. Tactic approval to critique the new arrival's technique.
We pulled into an empty cove one early afternoon and within an hour the Rye Harbor Yacht Club cruise arrived. A sorrier bunch of sailors I've never seen. One skipper threw out the anchor leaving the main sail up and cleated and proceeded to swim ashore. His boat took off in a gust and dragged directly toward the most pristine wooden boat in the group. The poor target had only a single small fender aboard and kept moving it to the expected point of impact. Talk about great fun people watching!
