That risks wasting his dive time and distracting him from safe diving. I am sorry to flame, but I feel I must, this one time. > [a helicopter motor and rotor with a parachute harness for a man to wear it > on his back] ... Maybe George will include this set up in the WKPP dive > equipment protocol. ... an underwater helicopter apparatus ... Not to dive with!! To fly with, for spotting from the air, to get a man quickly to where the boat can't to, and many uses that a big craft would carry a helicopter for, but scaled down, whether the boat is a diving boat or not. It would have to have two coaxial rotors counter-rotating (= rotating opposite ways), able when not rotating to dangle down the shaft so they don't catch on things when he is walking about on the ground or in a boat wearing it.
