Joe,
As you only
have buoyancy in the pontoons and not continuously under the submersible, the
pontoons will have to be increased in length to gain sufficient buoyancy to
float the combined sub and pontoon boat off of the trailer. The increased
length may be an issue in getting the combo off of the trailer on steeper
ramps.
Aren’t I
just a killjoy J !!!

Incidentally.....this
is not fully submersible as the LRT barge, it is semi-submersible. The level of
upper flotation is set to float the sub off the deck by (X)"....(better be
a damn nice flat day too)!
If this
proves mathematically stable enough to be viable, you would launch this from a
standard trailer, in "skinny water", then tow to the dive site, just
like the LRT barge, then vent down the pontoons. Your 1500w generator, blower
and other goodies stay dry above on top of either aluminum, or
composite foam filled floats.

I seem to keep coming back to this particular solution,
probably because as a mechanical guy...I can figure out how to build this. As a
pilot, I can visualize CG, W&B and forces at work, but what I am
not......is an engineer.
That lack of knowledge and my desire to build a successful
and uniquely spectacular project, is partly the impetus to pursue Naval
Architecture,.... but I am not there yet. I do not yet know how to
calculate for surface stability of floating bodies, but I do have an idea of
what's required.
the link below is in case the photo won't load
My post to Rick about width is what it is.....a guess.
Would this be unstable at 8.5' ???, the key is in the math. Somewhere in here
is the answer to this particular option. I'll let Jay speak to the sea sled
option as it's beyond my ability to envision it.
Thanks to everyone for the participation, the results are
self evident.
