Except for calm lake conditions I don't think a piggy-back generator
is practical. On open ocean it is not a simple task to support sub
dive ops. Take another look at the "psychedelic sub" video from
Islamorada this year and note the bobbing of the sub, the divers,
and the support boat in only 2 foot seas. Having been in that water
helping weight-balance Snoopy, I can't imagine trying to load/unload
a generator (even a small one) from the top of it.<br clear="none">

A small semi-rigid inflatable also won't be practical as surface
support in such conditions. Doug's 25 foot boston whaler was being
tossed pretty well and drifting heavily. Who wants to be 5 miles
out on the open ocean in a small cramped inflatable fighting wave,
wind and current?<br clear="none">
