Re: PRV 2 was Re: [PSUBS-MAILIST]
Hi Dave,
Most of the ambient dry and semi-dry subs that I know of have a bottom
entry. SportSub for instance is a semi-dry sub that you enter into from
underneath.

occupants usually have to swim in from the bottom? Or do you have to seal a
hatch in the bottom, enter through the top, seal the top hatch, and then open
the bottom one before diving? I mean, otherwise it'd just sink like a regular
boat with a hole in the bottom, right?
