Re: [PSUBS-MAILIST] Depth

Vance, I am interested in knowing more about the “survived several months submerged on a wreck” story.

Thanks,

Steve

Both are capable of 350 but Captain Kittredge's native caution came out. He wanted to make sure the acrylic dome would not be overstressed. One of those failed in a full hull pressure test at just over 800 feet, so he settled on the nearest third of that, rounding back. The 350 is almost the same hull, with T-bar ribs instead of rolled angle iron and a steel conning tower to replace the acrylic dome. One of those survived several months submerged on a wreck at nearly 700 feet without damage.

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

Alan
