Hi Big Dave, some answers you find on the mail to Alec. 

The Boat overall is 20 m (66 feet with 1 feet = 0,3048 m ) long. 
The pressure hull of 2,4m Diameter has a lenght of only 10 m (33 feet). 
In front and aft the pressure hull are the hard dive and regulator tanks
(its a combination of both) with 3 feet long each.
One endcap, symbol = (,  or ) , of this tanks goes outside the other
goes inside to the pressure hull like :  
bow(tank)pressure hull(tank)stern.  
The rest is free floading anti-collison areas inside bow and stern. 
The reason for the big frame distance is the small amount
of money the builders have had. 

The displacement is 45/55 tons. The engine is a 160 HP Diesel. 
No other drive engine. The boat dive today only static on one place. You
will find a picture of the sub on on "my" page of Ray's great Homepage
at PSUBS Picture Gallery with the titel "Spurdog". 

I have sleep inside last weekend and it is very nice to sleep 
in such big submarine. No sound of the Live support system - there 
is no L.S.S..- much Space and air inside. And if you switch off the
electric light - than it is night inside - the hole day - good time to 
drink some bottles of wiskey and discuss about the mad and poor people
which have not a submarine..
 
And - hi Karl, the data I have giver to you about this
sub are not longer secret - the dive deep is to shallow for me..

regards, carsten - any other second hand autonomus sub out there ? 
It should be bigger than 30 feet and smaller than 90 feet..
 
regards, Carsten
