  Again: how much work has been done on the hydrodynamics and swimming drag of
sport scuba gear? And the drag and rotation-inertia when the diver rolls over.
About time someone raised this point. And, as he said, the more bits trailing
off, the more to catch on things, and the more to go wrong. Oh for a handy
light streamlined naval-type oxygen rebreather, plus a reliable medication to
suppress oxygen poisoning down to say 7 bars = say 200 feet / 60 meters.

  (And as underwater small craft technology develops, in the future some may
complain that a lot of bits trailing off a sport scuba diver catch on things
and get in the way when he has got somewhere where [some navy men or shellfish
fisherman say that] he shouldn't be and their inshore patrol and cleanup sub
has scooped him up and is pumping him through into its collapsible dredgings
and flotsam tank for disposal.)
