Alec,

I like the idea of pontoons as a self propelled boat lift, (I-beams are your friend here). This makes the load and the vessel a single unit as opposed to separate masses wrangling along in a seaway.

In fact, I suspect a pontoon lift ala "Lulu" (albeit small scale), is the best possible surface support solution for the little guy.

How about a small catamaran tender running A/C and blowing cold air into the sub when in transit? Sub could snugged up against it from beneath, not actually lifter on deck.

Alec,

Your experience renders what I had in mind for the K-350untenable. That post was very helpful as I am quite familiar with the conditions.

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 accommodate two with comfortably and practically with all of the electronic goodies I have in mind.

On environmental, this is a conundrum caused by a subtropical environment and lack of appropriate surface support.There's no getting around the fact that if you don't 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.

One could conceivably plumb theexhaust water 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 toscavenge 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.

I don't like an internal diesel for such a small enclosed space, what to do with the generated heat is avicious 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.
