The open transoms on these lobster boats facilitates dumping lobster traps en masse ... all the lobster traps are tied together individually and to an anchor; the anchor is dropped and the boat keeps motoring along, pulling the traps out one-at-a-time in a long row. These boats are run by individuals (a captain and a sternman) and may be put out of business by government regulations aimed at protecting endangered Right Whales from line entanglement. But no Right Whales have died from entanglement in U.S. waters, only in Canadian waters; and the regulations favor large "factory" lobster boats ... so the local fishermen who have been doing this for generations are frustrated/angry.
