Re: [PSUBS-MAILIST] pressure hull sizing



David,
Why are you quite sure 5 feet is too small? Quite a few very successful subs 
were built and operated with a 5 foot hull. 7 feet, on the other hand, is 
very large. Several subs operate with this size hull today and carry three 
people. Do some research into subs and see if you can't find some information 
on small subs. You'll be surprised at how small small can be.
