Those are V-clamps, like the ones Sta-Rite and other pool pump manufacturers use for casing clamps on their pump bodies. That was a standard deal on Perry subs. Phil doesn't use them, by the way. Even in the old days, Hyco bolted the pod ends on Aquarius (lots of BIG bolts). The clamps are quick and easy, but I've seen more than one of them knocked off or damaged. It's really unhandy when you lift your million dollar Perry out of the water and watch one of the pod covers go bloop, right into the drink. Let's see. Spares? No, we don't have another one. Damn. What now? Hmm. Somebody get the Scotch. I need a drink.

Jay, I had been thinking about how the battery pod caps on the Triton 1000 were being attached, and figured it would be a lot like the beveled clamping means your talking about. But using a small hinge like is used on these tri clover clamps we use at the winery to attach and seal hoses to tanks and what not.
It's hard to make out the hinge on the Triton pods, but you can see one on the top of the starboard pod in this rendering of the sub if you look closely and the tightening bolt on the bottom.
High pressure tri clover clamps.

Brent,
Did not look closely at the unit that was on our pier a short time ago but from inspection of the images, it looks like the mating unit is one or the other but not both. The two-part clamping ring interfaces with beveled surfaces so that when the tighter it is drawn together, the more pressure is put on the flat mating surfaces.

Jay,
So does that mean they can be locked by both a rotating ring type, as well as a two-part coupling flange, as it appears this DART unit can? Are all the outer mating parts of the two-part coupling flange beveled so they increase the pressure on the seal further as the two clam shells are brought closer together?
