Frank, It is not just stopping fast, it is also what happens to items inside the sub. Our Navy speaks of “missile hazards” plus you need to think about your own body being thrown against the inside of your sub. The death in the sub that hit a sea mount in the Pacific a while back was due to a watch stander being thrown in the lower level of the Engine Room, far from where all of the collision damage occurred.

From: owner-personal_submersibles@psubs.org [mailto:owner-personal_submersibles@psubs.org] On Behalf Of ShellyDalg@aol.com Hi Jay. Ya, for that kind of money it should do something. Going fast may be fun but like you said, not very useful in a sub and ultimately quite dangerous. I'm wondering not only how fast my sub will go, but also how fast it will stop. Turning is something too. The sub's weight, plus the ballast tank water trapped inside, makes a pretty heavy weight to stop quickly. If I crash into the proverbial " immovable object " like a big rock somethin's gotta give. I'm hoping the sub will be maneuverable enough to avoid ramming things directly and I've put "bumpers" into the FRP design to absorb shock. They might break but are fairly easy to repair. Can't wait to see how this thing really works. Frank D. |
