This makes the load and the vessel a single unit as opposed to separate masses wrangling along in a seaway.<br/><br/>In fact, I suspect a pontoon lift ala "Lulu" (albeit small scale), is the best possible surface support solution for the little guy.<br/><br/>Joe<br/><br/>Sent from Yahoo!

<span style="">On the first problem, I'm inclined now to widen the hull and dispense with the conning tower completely in favor of a low profile hatch. This would be surrounded by a free flooding FRP tower ala Alvin. The question now is what diameter
to <span id="misspell-3"><span>accommodate</span></span> two with comfortably and practically with all of the electronic goodies I have in mind.</span></div>

<span style="">On environmental, this is a <span id="misspell-4"><span>conundrum</span></span> caused by a subtropical environment and lack of appropriate surface support.
<span id="misspell-5">There's</span> no getting around the fact that if you <span id="misspell-6">
<span>don't</span></span> own an RV Atlantis with a dedicated sub hangar and A-Frame, then a radical but practical home grown solution must be found if you want to dive in Florida.</span></div>

<span style="">One could <span id="misspell-7"><span>conceivably</span></span> plumb the
<span id="misspell-8"><span>exhaust water<var id="yui-ie-cursor"></var></span></span> circulation of a 3500 BTU marine air unit to an external heat exchanger and scavenge the condensation to an internal water tank trim system. This unit could be powered by
a removable portable Honda gas generator riding aft of the tower while on the surface. The idea is to
<span id="misspell-9"><span>scavenge</span></span> all of that water and cool the interior prior to diving. The unit could be shut down or run off batteries after removal of the portable gen set depending on conditions.

<span style="">I <span id="misspell-10"><span>don't</span></span> like an internal diesel for such a small enclosed space, what to do with the generated heat is a
<span id="misspell-11"><span>vicious</span></span> cycle, and a separate machinery hull is asking for trouble ala Pisces III. In any case some measure of surface support for battery charging and HP exchanges is a must.</span></div>
