Re: [PSUBS-MAILIST] Decision Time.

[MerlinSub@t-online.de]

James, 

first calculate how many pressue-air you need to blow the boat 
inside dry to ambient on max.deep - and than go for the window solution. :-0

I drive Nemo sometimes. And feel very weel with this simple, 
cheap and easy maintance dome exit solution. 

Make sure that the flood vales have a large diameter and that a pipe 
goes from the flood vale to the bilge so that that the violent water rush in 
can not hit or cool your body during the minutes you flood the boat. 

regards Carsten

However, this i think will take a lot more work to build, plus i will need to adjust the distance of battery pods from the hull among other things.
