<div><font size="3">I like the latch mechanism - looks very clean, adjustable rods, pivoting dogs. I don't see wiring or sensors either, but they could be on the dog just out of the pic at the top. The sub is GL classed. Makes me curious.</font></div>
<div><font size="3"></font> </div>
<div><font size="3">The OP system seems to cover all the bases. Cutoff valve (red handle) in case the AOP fails open; manual OP valve (blue handle) if the AOP fails closed or to relieve underpressure; and the bend will catch any minor drips. Seawater will have to be backflushed. If you pulled vac before diving and the sub cooled while submerged, you could easily have underpressure when you surface. </font></div>

<div>Thanks Jim,</div>
<div>That was quite interesting.</div>
<div>In the hatch picture they have a stop valve with a bend, then an over pressure</div>
<div>valve & a manual valve for a final pressure equalisation. This conforms with G.L.</div>
<div>to that point but I can't see any mechanism that ensures full equalisation before</div>
<div>the hatch is opened. Also I couldn't see any wiring or mechanism that would relay</div>
<div>Information that the hatch was open (might be out of view).</div>
<div>Re Jon's comments about interior colour ; I've heard that dark is the way to go</div>
<div>to avoid ghosting on the inner surfaces of the acrylic.</div>

I notice they had a much calmer sea then we did for Snoopy out on Pickle Reef.
They have a cover over the dome to block the sun prior to diving and I noticed a
huge difference in colors within the sub due to the blue ocean light. Look at
the VHF handheld radio in front of the pilot before diving and submerged. I'm
thinking maybe I'm going to want to change my electronic displays to blue
instead of red.

All,
Gizmag had a good article on U-Boat
Worx' C-Explorer 2 sub. The link below is to a pic
of the hatch latch mechanism and some plumbing which I
presume includes the OP valve. Lots of other pics
there to scroll through as well. -Jim
