I like the gas struts mostly because I think they
are simple and clean, low weight, quiet, easy to obtain, not really expensive,
and they give you a nice smooth motion.
Here are the images I was looking for, showing the gas struts on the
exterior free flooding area, under the Subeo, Gemini hatch fairings.

The Deepworker 2000 has a really clean and simple internal mounting means
using gas struts.

Here is a image of the S101 with two gas struts mounted internally.

These two pictures show the Deep Flight Aviator
hatch assist means, that look like there might be large gas struts mounted
externally.

Antipodes/XPC15/PC-1501 Hi Cody, Nice to see ya come in out of the cold. ;} Your speaking of submerged stability here I figure. So when submerged your dealing with mostly the hinge weight. I wouldn't expect that to be to much unless you have one of those 3 ton spring hatches I've seen. ;} But yes if it made you list to one side, you could just shift some weight to the other side some place appropriate. The hinge Greg Cottrell worked up for the Great White K-250 out of mostly plastic is nice and light. I've put together a very small and light hinge means that uses the ball joints you see on the gas struts on car hatches, S101 and the Deepworker hatches. I'll also be using the full gas struts to lift my hatch like the deep worker hatches are from the inside. I've also seen them used on the exterior or the sub. Then I'll have a little spring system, that allows for the hatch to move down on the hinge side as the hydrostatic pressure increases. This will make my hatch hinge nice and quite when I open it. No clanking for me.

I currently have a CT crash guard in the way of doing that, and I think I want my hinge in the back for the KLH-500. I just finished some FEA work on the acrylic cylinder for the new CT config. a few days ago. It looks like it's a tough beast.

MBT without effecting the trim overmuch, from the look of things. He's not a big
man, but the hatch off center and Pete off center combined tell me that the
Antibodes is pretty much rock solid on the surface.

opening to the side on a PSUB the size of a K-350 is probably not
feasible due to hanging all of that weight over on one side at height will
result in a severe list. And some loss of buoyancy will also occur as the opened
bottom ballast tanks burp.

this is pretty much my CT minus the hatch. The CT bolts on so I guess you
can change the hinge position as desired. This is the first orientation to
the side I have seen. I was wondering how you could tell that the dogs can
be operated from the exterior?
Thanks,
