Brian,

Did PRV2 originally have a diver lockout?  I wonder if it was spec'd for 
remaining water after a lockout dive.  Or maybe in case of excess water 
due to rough water getting in through an open hatch on the surface?  
Perhaps one of our sub-owners who have some dive time behind them can 
comment on the necessity of a bilge pump.  There's a certain amount of 
water that will accumulate due to condensation and semi-dry 
entrance/exit from the vessel, but I don't think that would necessitate 
the need for a bilge pump.

In regard to kort nozzles, you are correct that specific design is 
necessary to get additional thrust through positive/negative pressure 
differentials.  Check the archives because I think we did have a 
discussion about them in the past, but there's much info on the web as well.

Jon
