<div style="RIGHT: auto"> </div>
<div style="RIGHT: auto">It looks to me like Alvin's thrusters all have a 90 deg drive arrangement like yacht bow thrusters. Some of these off the <SPAN style="RIGHT: auto" id=misspell-0>shelf</SPAN> units are hydraulic, but way over powered for a Delta / Gamma sized sub. <SPAN style="RIGHT: auto" id=misspell-1><SPAN>There</SPAN></SPAN> are however, lots of little hydraulic motors out there, a slew of them. Ive also seen drive components, reductions, etc, that simply were not available to George. How much trouble would it be to go hydraulic all around? </div>
<div style="RIGHT: auto"> </div>
<div style="RIGHT: auto">If DC motors must be used, in my view then the single must have improvement to the T-Rex design is the addition of a mag coupling.</div>
<div style="RIGHT: auto"> </div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto" id=misspell-2>Alecs</SPAN> <SPAN style="RIGHT: auto" id=misspell-3><SPAN>experience</SPAN></SPAN> has me rethinking self sufficiency. It would be nice to charge the batteries and the HP tanks independent of a surface boat, eliminating the need to raft alongside in swells. All this <SPAN style="RIGHT: auto" id=misspell-4><SPAN>convenience</SPAN></SPAN> means a "Tours 66" type of arrangement. But Tours 66 weighed in at 10 tons.</div>
<div style="RIGHT: auto"> </div>
<div style="RIGHT: auto">Everything is now downsized like that little AC unit I posted,.. take a look at this marine gen-set (note dimensions) <A style="RIGHT: auto" href="http://www.nextgenerationpower.com/Info/Support/3-5Specs.pdf">http://www.nextgenerationpower.com/Info/Support/3-5Specs.pdf</A> </div>
<div style="RIGHT: auto"><SPAN style="RIGHT: auto" id=misspell-5>Hmm</SPAN>, could this not be enclosed in the hull during a build, or otherwise slung longways down the hatch into a 42" hull? No prop shaft and seals, (you still get towed) but <SPAN style="RIGHT: auto" id=misspell-6><SPAN>independent</SPAN></SPAN> re-<SPAN style="RIGHT: auto" id=misspell-7><SPAN>charge</SPAN></SPAN> capability for both batteries and HP air with an equally downsized compressor!?! </div>
<div style="RIGHT: auto"> </div>
<div style="RIGHT: auto">So the question of the day is,...</div>
<div style="RIGHT: auto"> </div>
<div style="RIGHT: auto">Is a comfy air conditioned & self sufficient research capable PSUB for sport diving in Florida / <SPAN style="RIGHT: auto" id=misspell-9><SPAN>Caribbean</SPAN></SPAN> waters, a realistic goal at around 3.5 tons and $8-$10 lb?</div>
