RE: [PSUBS-MAILIST] Depth

Alan,

 

There is very little diffrence in cost for a 150 or 300 feet sub. Just normal steel and ball valves.

Below 200M /700Feet jou come in the range of special valves ,penetrators, steel, welding etc.

 

\So better built a 300+feet sub.

 

Emile

My dry, one atmosphere, two person submarine will be diving in fresh water only.  The water will be quite cold.

 

I get the impression that most of the interesting sights are within 150’ of the surface.  Is that correct?

 

However, I also get the impression that a submarine with an operating depth of 300’ is only a bit more expensive than one with an operating depth of 150’.  Is that true and, if so, how much?

 

The Kittredge subs were designed for 250’ and 350’.  Was there some significance to those numbers?

 

Thanks for the help to-date
