Les, I can happily run some test cases this weekend to figure the hull material weight of your proposed sphere, but if your concern is the ultimate handling / trailering weight, as a functional submersible that is going to be exactly the weight of an equivalent sphere of seawater, at ~ 1,025 kg/m^3. For your 2m sphere, that will be 4,293.5 kg or 9,465.5 lbs. Sean On Wednesday, October 22nd, 2025 at 19:00, via Personal_Submersibles > wrote: After many years and many hospital holidays, ?

You might be referring to the excel spreadsheet calculator which is available on the web site, no membership necessary. You mentioned 150 meters or 160 psi, however 150 meters will put you at about 222 psi whereas 160 psi will put you at about 109 meters. Using imperial units and A516g70 material, the spreadsheet is showing me that 1/4 inch thickness provides 175psi and 3/8 inch thickness provides 314 psi with a safety factor of about 1/3. However keep in mind the calculator assumes perfect material, perfect sphere shape, perfect welding, and perfection for every other element of fabrication. It's only a guide, not definitive.

Les, there was a sphere around that size that was part of a submersible owned by Brian Cox, who passed away a few years ago. I am not sure what happened to it, but someone else listening in may be able to tell you. It was the one redeeming part of the sub, the rest was questionable.

Registration for PC2026 in Islamorada is now open.? It is important that we get a headcount for anyone making the trip to Islamorada so please register online via our website at http://www.psubs.org? Just follow the links to PC2026. DATES Feb 11-14, 2026 ? See web site for schedule LODGING Due to peak season high accommodation costs, no designated hotel or group lodging is planned. ? For this reason, each attendee will need to seek out accommodations that fit their needs and budget. ? The most cost effective lodging at this time of year will be multiple people sharing an AIRBNB or VRBO rental. For traffic and travel convenience to events, we recommend you seek lodging no further north than Key Largo and no further south than Marathon. SUBMARINES We currently have four submarines attending; VAST, SNOOPY, Shackleton, and Aquatic.? If you have a submarine (regardless of condition), we want to see it and welcome you to join us.? Please contact admin at psubs.org for details. ? SPEAKERS Our technical session will be Sat Feb 14, 2026.? If you would like to make a presentation to the organization either in person or remotely via ZOOM, please contact admin at psubs.org.? Whatever you are working on or have expertise in, we want to hear about it. Our current lineup includes a discussion with the US Coast Guard regarding regulations affecting small manned submarines, a presentation by Aquarius Reef Habitat personnel from Florida International University who will discuss the history and future of the Aquarius underwater habitat; and various presentations by PSUBS members who will share updates on their submarine projects. HOW YOU CAN HELP If you are planning to attend in person and have SCUBA or boating experience, we can use your help.? Please contact admin at psubs.org for details. EVENTS Please note that if you are attending in person this is a free event.? However, participation in some segments may require that you contribute to paying some of the costs.? For example, we have two diving days planned for Feb 12 and 13, however we may not have enough room in the surface boats for everyone that wants to view the diving.? We may be required to rent a boat and split the costs between those that want to view those dives from a surface boat. DAY 1 - FEB 11, 2026 is an exception and being dedicated to prepping vessels for diving and performing?sea trials within a controlled shore based environment. ? All attendees are welcome?to observe and/or help launch and retrieve the vessels.? This will be an excellent opportunity to get up close and personal with multiple submarines and see first hand what is involved with operating them. STAY TUNED for more details as we move closer to the convention dates.? Updates will appear on the web site and also communicated via our mailing list and FaceBook page.

You will probably have corrosion in the wiring caused by wicking ( wire hot after operation sucks in water as it cools). You can replace the wiring but will probably get away with it seeing the wiring should be reasonably thick.Did you not have air compensation?Regards Alan Yahoo Mail: Search, organise, conquer On Sat, 29 Nov 2025 at 11:46 am, Rick Patton via Personal_Submersibles wrote: Finally got her wet! my port thruster flooded and was wondering if anyone else had that happen and were they able to recover it? some water in the bilges which was a bit disconcerting so next time in, there will be no floorboards.?_______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles _______________________________________________ Personal_Submersibles mailing list Personal_Submersibles at psubs.org http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles -------------- next part -------------- An HTML attachment was scrubbed...

I would think that if that was the problem the other two would have flooded? I'll check it out. Will it explain how to adjust it?
