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.
There are a variety of choices you can make here, mainly concerning adjustability. High-end second stages come with one, two, or even three adjustments. Some are actually useful, others are pure marketing nonsense. With thick gloves on, you may not even be able to work them in the water. All user-accessible adjustments have a much narrower range of operation than the internal adjustments that a technician can make. My experience is that if a reg is malfunctioning, the user adjustments will be useless to stop it. On the other hand, if you're a gadget person who likes to fiddle with things, some of the adjustments actually can make a noticeable ( although not essential ) difference in breathing. On the theory that extra moving parts are extra failure points, I would avoid adjustable regulators, but that's not really possible anymore. With most manufacturers, the non-adjustable regs are the bottom of the line, and you don't want that, so buy a good reg, and if it has a few useless bells and whistles, live with them.
