Re: [PSUBS-MAILIST] endcap/bulkhead question

[Warren Greenway <opensourcesub@yahoo.com>]

The junction between the caps and hull "tube" will be
under tremendous stress. There will be shearing forces
on the wleds. Also, you are creating less useable
interior space for a given displacement. I think those
would be some of the basic reasons. Reference Concepts
of Submarine Design for more specifics.
