Hi - my two cents. 

Herve is right - for the reason thats the most Psubs are in a divedepths
were a dive exit can be survived - 
Psubers should have Scuba dive expirence. Also a dive course give you
the expierence about human bodys 
under pressure..., under bouancy, under water.. 

No need to find new rules - ABS, PVHO, GL, LRs etc based mostly on
expirence. 
Just purchase the books and decide foryourself what is useful for a
small sub and what not. 

But a basic example calculation with drawings - made from somebody how
has allready build 
at least one usefull selfdesigned subs will help much more. 

Also a short list of absolut nessesary requirements can be displayed
here on psubs - like : 

A Psub should have : 

- A drop weight
- A hatch which can be easy open from both sides
- A scuba gear for each person
- A lifesupport system according to classification rules
- A security Diver(s) during the first test dive. 
- A calculation of weight, bouancy and trim
- A .. maybe some other points - but not to much. 

Boats which not fullfill (most) of this basic rules or equal solutions 
should not to be displayed on the Psubs Picture Gallery.. or even on a
convention..   

- A Sub with propane in her softanks should be - blown..
