Has anyone seen the old conceptual sketch I put up on frappr? The idea is
to have a pontoon section attached to the sub with a quick disconnect, and the
pontoon section stays afloat with genset, winch, compressor, communication base,
( and sun shade with cooler full of beer!) and most importantly......an outboard
motor which will drive the sub/pontoon section to the dive site quickly. A
hundred horse Merc should push the craft at 15 to 20 knots so a dive site 2
miles off shore could be reached in an hour or less. Separate the two, and take
er down. If the depth is fairly shallow, stay tethered to the pontoon with air,
elec, and wired communications, plus a steel tether to keep you from getting too
deep. Pretty much gives you unlimited bottom time and unlimited power ( size the
motors to overcome the additional drag caused by the tether) and should be
pretty simple down to say 150 feet deep.
For deeper dives, cut loose, and go on battery power alone, but with the
pontoon section being driven around on top by the surface crew.
If you never wanted to go deeper than 150 feet, you could use an all A.C.
system with big motors and run a 220 volt power supply down to the sub, fed by
an onboard genset.
You'd still need battery back-up to run the C.D. player, and all the other
back-up systems like air, but you could run some really big thrusters.
Sorry guys.....Just mind wandering.......Frank
