Cape May reef also contains large numbers of tire units and Army tanks (not shown) concentrated in the center area that appears here to be empty. This reef also received 50 redbird subways cars, which are not plotted.
The Coast Guard classification for this type was BUSL, for 'boat utility stern loading'. These boats had facilities to maintain the crew for 48 hours. They were powered by a diesel engine driving a steerable propeller, which would have made them extremely maneuverable. They were replaced by a 49-foot model.
The United States Coast Guard has donated a number of vessels as artificial reefs over the years. They seem to be sensitive about having their vessels shown in a "bad" way, and typically paint out all the markings before turning them over.
