RE: [PSUBS-MAILIST] Vertical Hulled Sub

This is nice, simple, and very stable. But I see two problems with it. The visibility through the dome is like the K-250, very good but unfortunately in a direction that is almost useless when submerged. In the K-250, when underwater you try to see what you can through the viewport at your feet, because the dome doesn't allow you to see the bottom. The second issue I see is that with this hull geometry, your viewport is always going to be very high above the bottom.

What an interesting concept! That's really different, I was originally looking at the iterations of the "Florida Manatee" and there was one which showed the side length-running ballast tanks were turnable, so that the sub body could be rotated to vertical with the MBT's still holding horizontal, providing surface support. It was just a quick sketch but I used to think it had something to it.

I've found the perfect picture of what I'm looking for but can't figure out who made it. I'll put a link to it here and maybe someone can shed some light on its designer. It looks like a SolidWorks item... I saw it and I was going THATS IT!! THATS IT!!! lol. I've already made modifications in my mind, decided equipment placement and made some changes, but the basic idea was perfect.

I kept trying to improve on the MBT design, to improve freeboard. I've decided that the inner edge of the MBT should have a vertical lip, which fits into a locking groove which runs around the hull, and locks it into place from underneath. Then several bolted stantions from the outer lip to the hull would provide ridgidity, and !!! would make the whole MBT somewhat easily removable. There would be just enough cast lead or steel on the inside at the bottom to always maintain a vertical attitude, so as not to spill a load sideways. And the emergency drop weight is actually a steel/lead ring, which slips over the bottom end of the hull, and is held in place by two thru-hulls so that it fits semi snug at the very lower edge of the hulls cylindrical part. The props would most likely be replaced with a single prop stationed via an arm straight out in front of the hull, and trainable, allowing for forward, sideways and rearward movement. VBT would likely be in a seperate pressure tank underneath the MBT shroud. The trailering sounded interesting.
I decided on a vertical trailering approach, in order to avoid hassle. The trailer would have a circular stand which fits around the hull, and holds it upright, though is hindged from the back, to allow it to open up like arms, un-hugging the hull when it is in the water and allowing it to bob away. If anyone has actually been able to visualize any of the things ive just mentioned, while looking at the picture and go "yeah I think I see what he means", let me know what you think.
