[PSUBS-MAILIST] New submarine

[Alan]

Wow, that student version of Rhino is cheap. You could buy that
for now & get the Orca & scan & solve later on when you are profficient
with Rhino.
I bought all 3 programs through a local distributor.
Jay Jeffries, who used to be on Psubs, sells Rhino & Orca.
He is a Naval architect, marine engineer, marine surveyor, nuclear technician etc.
Someone may know his contact details. I lost contact.
They offer a free evaluation version on the site you linked to, but it won't mean a lot unless
you buy a good instruction series or go to tech.

> G.L., Section 4, Design Loads, Table 4.1 says that for your designated depth, the collapse diving pressure divided by your nominal diving depth, has to be more than 1.73, & your test diving pressure has to be more than or equal to 1.2 x your nominal diving pressure.
> So for a maximum operating depth of 1000 meters, build to a crush depth of at least 1,730 meters & test to a minimum of 1200 meters. In table 4.2 it is a bit confusing, but I am reading it as saying the view ports are to
