I find 20 kts. on the surface to be hard to believe as there is
a limit on the speed due to hull displacement (max speed ~3.46 x 
) if I
remember correctly). There is no way that the S101 could be a
semi-displacement or planing hull.

Hi. I'm wondering about the " 3 tons" comment. That's a
lot of batteries! Have you made any concept sketches yet? Sounds like a nice
big one!
Didn't that S101 have about that many batteries? I remember some
where it said they could reach 20 knots for short bursts. I think that
was surfaced and on diesel power, but still would be really nice.
On battery usage.....my 4 Minnkotas at 46 amps each will probably
start a fire if I run them all at full power. I've got an electrician friend
who will be advising me on the electrical system. I have considered using two
sets of batteries. One in use and one on charge at the dock or on board the
support boat.( looking at pontoon boats right now ) I still think about the
original concept of using a tether down to say 150 feet, with a 220 line
powering the motors running off a gen set on the surface. Seems like you could
power around submerged all day, and if a problem developed, use the batteries
to ascend. The extra available power could offset the extra drag from a line
and cable. That doesn't address the entanglement issue, but it would make it
possible to put a 20 horse electric motor on board. Bet you could fly with one
of those!. Frank D.
