Hi John,

how long do you intend have your sub sustain speeds of 10 knots?
The idea of 25-30Kts is rather infeasible with battery power
alone (I will be happy to be proven wrong, of course).

And yes, I would I (and probably everybody else on the list)
would love to see some drawing/pictures.

I am also working on a larger live-a-board style sub design,
but the speed range I am aiming for is more like 1-3knots.

Cheers!
 Ian.

Hello Again thanks everyone for the shaft seal info, I 
appreciate it. I am down to only a few more things I need to know, the electric 
motor. For me I will want to travel at a speed of 10 knots under 
water
but  I would like for there to be a 
possibility for me to go faster, say, 25 to 30 knots. I know it depends on the 
dimensions of the sub, it will most likely weigh 50 tons since it is 60 ft and 
10 ft inside diameter. this is not a cylinder shaped 
sub though
if you want a picture I will give it to you just tell 
me. I thought about a 70 kw motor but I don’t know if it will give me the speeds 
I want. And if you can, I want to know what the best battery would be to power 
the sub with lots of electronics and appliances (TV's, microwave, water pumps 
etc.)
I await your assistance.
 
John
