working off of a radius for 20 inches, and four feet long from weld brace to 
weld brace, I've got about 700 feet before your hull crushes.
Give me your radius, length, and wether it's steel or aluminum, and I can 
give you a more accurate pressure table.
(This is working off of Roark and Flugge's calcs)
