Re: [PSUBS-MAILIST] material availability.
Hi Glen,
since you are building a K350, which is pretty much a real
work horse, a fairly over built submersible, it might be
possible to use 6mm and still the view port Acrylic will be
the weakest part of the pressure boundary. I believe there is
a spreadsheet available some where on psubs.org which can be
used to calculate possible failure depths/modes. Also,
calculated the weight difference and add that to the static
ballast.
The other option is use 8mm, calculated the weight difference
between 6.35mm and 8mm, then remove that from the ballast to
still maintain the same overall weight. This will change the
handling properties a little, with more weight around the
circumference rather than is lower down in the static ballast
area. The vessel will be slightly more unstable.
Another option is to use 8mm and length the hull to increase
the volume and displacement enough to maintain the same
static ballasting proportions/center of gravity (increasing
the static ballast as needed). This would probably be the
option I would pick.
I was raised in the UK, the moved to the US. I switched from
metric to US system after a year or two of moving to the US.
Now I've switched back to metric and I'm much happier or maybe
just more comfortable designing/work that way. I'm sure every
body has their own favorite system they feel most comfortable
using. I do get some cold shoulders/brush-offs asking for
metal in mm around this area (California, San Francisco Bay Area).
Much the stuff I'm drawing up I try to calculated so that it will
still function with in it's parameters (e.g. test depth)
regardless if it's construction from metric or the closest US
system materials.
Cheers,
Ian.

>Inches to metric .After 1 month of trying to get my material from countless suppliers to build my k350 in south Africa a metal producing country I am starting to get thoughts of giving up when I mention inches it seems to close ears when I convert to metric i.e. 1/4''=6.35mm(we only get 6mm or 8mm) and the list goes on

> During the last three years, significant investments were made in the engineering, development and testing of the C-Quester concept. Therefore, U-Boat Worx is now very excited to present a new and exciting generation of C-Quester Submersibles that combines a full Germanischer Lloyd classification with our experience, knowledge, and enthusiasm.

>
>
> The newest submersible to be launched is the brand-new three-person C-Quester 3, which will be followed by the reinvented two-person C-Quester 2.
>
> Concept and Technology
>
> Uncompromisingly, the basic unique characteristics of the previous C-Quester Submersibles will still be maintained in the new C-Quester including the Underwater Boat Concept.
>
> Further expanding our competitive advantages, we have also introduced increased endurance with Lithium-Ion Technology, Extended Depth Capabilities up to 100 metres, increased surface speed of 4 knots, and Easy Modular Maintenance, just to mention a few.
>
> Who are our C-Quester customers?
>
> The C-Quester 3, with low operational costs, forms a solid business opportunity for a charter operation (resorts, luxury hotels, yachts). Also for personal use, the C-Quester 3 is the choice of the individual, who wants to share the world below the surface with friends and family.
>
> The C-Quester 2, with limited size and weight, represents the ideal Superyacht submersible. Moreover, the C-Quester 2 brings the underwater world within reach of private individuals that are looking for an advanced and easy-to-handle submersible.
>
> Availability
>
> A limited number (5) of certified C-Quester 3 hulls are now available to order, with open delivery slots in spring 2009. The C-Quester 2 hulls can be secured with open delivery slots in the summer of 2009.
>
> We invite you to join us in exploring the new boundaries of the new C-Quester Submersibles. You are most welcome to visit our facilities in Breda, The Netherlands. We also invite you to meet us at the Monaco Yacht Show (24-27 September 2008) to get acquainted with our new U-Boat Worx product family.
