Thanks Frank, Working on it. It is something that needs to be
solved for all slow surface subs. John’s answer is the closest I have seen and
best value for money. Hugh From:

[mailto:owner-personal_submersibles@psubs.org] On Behalf Of ShellyDalg@aol.com Hi Hugh. Like I mentioned to Dean, it will take a pretty big
pontoon boat to handle a heavy sub. Your calcs at 40 feet sound a little
closer. A strong frame to hold it all together could be made with
"arches" on the ends so you could drive the sub between the pontoons,
and hoist the sub up. It would be pretty massive though. I visited the Delta Oceanographics team in Moss Landing last year
and they have a big ship ( 110 feet ) that they use for deploying their little
delta sub. It sits on the deck and gets lifted into the water with a boom
crane. I bet that ship burns 50 gallons an hour ! That's one of the great things about Phil's "Deep
Workers". Their small size and weight makes them very portable. Moving a 6 ton sub across 50 miles of open ocean is going to
require a pretty big something. Would it be possible to make a set of pontoons that would securely
attach to the sub's sides, thereby adding buoyancy to the sub to get it up
enough to reduce drag, but not right out of the water ? Then a tow vehicle ( tug boat size ) could pull the
sub/pontoon assembly to where it's needed. Maybe the pontoons could be inflated like a Zodiac boat. Frank D.
