RE: [PSUBS-MAILIST] Sub building business
I would love a ship like the Aquarius ( 3 man capable) - But I'll meet
you on the bottom to have a sandwich.

Personally I don't want to be smelling someone else's farts while I'm
trying to maneuver my sub, and I certainly don't need a back seat driver
either. Let the other passenger get his own sub! For me a one man sub is
better since space can be kept at an absolute minimum that way things
can be optimized for overall weight, handy when launching.
