[PSUBS-MAILIST] Sub for 2 people

[Douglas Suhr via Personal_Submersibles]

Kamil, to accommodate a second occupant in a K-250, it is necessary to
remove the hard (steel) variable ballast tank that would normally sit near
the floor of the hull (under the pilot's seat). Once this tank has been
removed, it is possible for a second person to lie prone on the floor of
the hull (with legs bent at the knees and feet toward the top of the aft
bulkhead) with the pilot seated above passenger (head in dome and feet
placed on both sides of passenger's torso). It's cramped for sure, but you
can work it out.

Snoopy is a good example of a K-250 that has been modified to accommodate a
second occupant. Another great modification to Snoopy is her saddle tanks
(much as you inquired), unfortunately they were an Alec Smyth custom job
and not detailed in the plans. You can see the saddle tank construction
detailed at the link below. ~ Doug S.
