Re: [PSUBS-MAILIST] Dif. Between Ambient & 1ATM

[Carsten Standfuss <Merlinsub@t-online.de>]

Kraka has this design. 

Ist a 1atm sub. With hull integrate diver look out hatch. 
Means the hole pressure hull is the diver lock out. 

A 1atm sub with is dry nad than later wet inside will be not possible
because of the heavy change of weight and bouancy. 
Possible is a dry chamner under pressure with a bottom hatch.
