I am not worried about transport and launching if I can keep it at that weight or less and I have the equipment to do it with my businesses. I would like to make it a cylinder, but may have to go to spheres. I would say you are right about a cylinder idea of 48". I would like to go with external rings if possible. </div><div>Thanks,</div><div>Scott Waters</div><div><br></div><div><br></div><div><br></div><div><br></div><div><div style="font-size:75%;color:#575757">Sent from my U.S. Cellular© Smartphone</div></div> <br>Jon Wallace <jon.wallace@yahoo.com> wrote:<br>Your biggest challenges beyond technical are going to be budgetary for both fabrication and operations. Whether you can succeed with a 5-ton weight limit for the parameters you have provided will depend upon the design. Using spheres will get you the most depth for the least amount of displacement but will also make interior design and occupant accommodations more challenging than a cylinder. For that depth and weight you are looking at a big trailer, big tow vehicle, and big fuel transport budget. Bionic Guppy is 7-ton so you may want to talk to JimK about any transport issues he's run into. BG is also designed for ramp use and Jim could provide input with issues related to launch/recovery at a ramp.<br><br>I can help you run numbers on the hull calculator if you give me the general diameter that you want to go with. I think BG is 48 inches and fits two occupants side-by-side in front of large dome and pilot behind them.<br><br>Jon<br><br><br><br>--------------------------------------------<br>On Tue, 4/8/14, swaters <swaters@waters-ks.com> wrote:<br><br> Subject: [PSUBS-MAILIST] New submarine<br> To: personal_submersibles@psubs.org<br> Date: Tuesday, April 8, 2014, 12:29 AM<br> <br> I am playing<br> with the idea of building another submarine.
