Risk to the swimmer

The text says "The helmsperson can leave the boat in slight reverse to stay on station with the anchor rode taught until the long-line operations are complete." If crewmember will swim a line from the stern to shore, I think it's a good idea to shut the engine off when the swimmer is in the vicinity of the boat. If a dinghy is used instead, there is a chance a crew member may fall into the water when boarding the dinghy.
