Adam - what should a diver do with 60 ts sub - heavy dammged 
- maybe half flooded on the bottom ? And can he find the sub in time ?
I know some really old german navy sailors  - leaving
there sub on the bottom of the Baltic or North Sea in 1944/45
 and some of them are still alive.. What is the problem with a flooded
valve ? 
It is easy to build, easy to secure, cheap - and just a additional
feature.. 
Same with the drop weight - most military boats have no drop weight and
survive over 20
years without any problem. But for civil sub it is in the rules.. 

Imagine you a trap in a sub - just in 60 feet of water - far out of
course from 
you dive plan.. The dead guys in the Largo M. in the mud trap "Tigerhai"
- no way out. 
The divers search for the sub over a half year..
