Re: [PSUBS-MAILIST] OSS spec sheet
The issue of beam seems to be causing a lot of concern. I want to
be able to sit upright in the hull. I'm not interested in crouching
or being balled-up in any way. Furthermore, 1.5-2.5 meters was the
unanimous response. It would seem, however, that there are a lot of
second thoughts on this. I am going to try laying out some stuff in
my living room to get a better idea of scale. I think this is the
first order of buisiness at this time. Please, all, make a mock up
with sticks, cardboard, or whatever, and get a solid understanding of
a realistic size. It is starting to sound like the 1.5 meters may have
been closer to the target. Remember, though, that the modularity will
allow the basic sub to be quite short, eliminating some cost/weight
concerns.
