[PSUBS-MAILIST] Sub (ish) story

[T Novak via Personal_Submersibles]

The Ortega is very sporty.  It's nice to have the high speed on the surface or when the viz is really good while submerged.  Very cool, and excellent range.  I think the pilot sits too far back; low viz and he won't see the bow of his boat.  Better duck behind the windshield otherwise your mask will be blown off your face.  It would be nice to have sideXside rather than tandem seating, but that would increase form drag.  At $100,000USD plus shipping it's outside of my allowance.  Sad, wet subs are my favourite.  I like the STIDD: dry and surface planing, cruises "backwards" under the surface so the pilot now sits right up front.  But it is too big and too expensive for recreational divers, but a great idea.  Maybe as a resort boat?

It was not meant negative. Their design approach is not conventional but okay. The even calculated the sub with CFD.

 

Just be careful with the “up” lever as it travel 11 Kts..

I'm not sure that if someone referred to me as "mentally okay", I would consider that a glowing endorsement.

These are ambient pressure vehicles, and there is merit in achieving fast descent rates - particularly on deep / mixed gas dives, as a 310 fsw dive would be, as it minimizes the contribution of the descent to the overall decompression obligation. That said, "seconds" sounds ridiculously fast for 300 feet, but on those sorts of dives I don't lolligag about with 60 fpm rates either.

The design is not bad. It is based on the WW2  “sleeping beauty” I know the designers personally and they are mentally okay.

 

But the textwriter of the article…” The safest submarine ever “ and “in seconds to 310 ft.” do not match together.
