<div><font style="background-color: transparent;">A true submariner!!! Like the old saw about the four old friends who played golf every Tuesday without fail. When asked why he was so late on day, one of the four explains to his wife that another of their number, Ed, had died of a massive heart attack on the third fairway. She was horrified but wondered still why they were so late. Well, says he. You can imagine darling, how long it took. Hit the ball, drag Ed. Hit the ball, drag Ed...</font></div>

<div>I don't think there's the slightest chance of the little hammer approach working. For a while, I used to pack a battery powered drill, and my plan was to drill out a circle to put my hand through. But the wing nut approach would take a fraction of the time. Plus, when you've dragged the dead pilot out you can put a new live one in and go diving as the hatch will still work!</div>

<div class="MsoNormal"><span style="font-family:; font-size: 11pt;">Well, that’s one I had to spend some thinking time on when PSUBS introduced the “convention diving prerequisite” that hatches open from either side. I eventually
came to a solution that was jointly developed with Greg Cottrell. We put a bevel on the bottom outside edge of the dome, and sealed it with an O ring instead of potting it. The dome floats on a flat ring of polycarbonate lubricated with vacuum grease, and
is secured only with wing nuts, so that in the event of needing to open the sub from the outside, that can be readily done without tools. It is not strictly speaking a hatch you can operate from either side, but it does accomplish the goal of emergency access.
I investigated other options similar to they've Deep Worker system, but could not come up with anything that would work – the difference is that the Deep Workers have a massive hatch ring, which gives you a lot more to work with in terms of locating through-hulls
or other hardware.</span></div>
<div class="MsoNormal"><span style="font-family:; font-size: 11pt;"> </span></div>
<div class="MsoNormal"><span style="font-family:; font-size: 11pt;">Personally what I would explore is closing the hatch with shock cord, so that in the event of an emergency you could just lift the hatch a little and slice
through the cords. But for that to work, you would really need nicely machined surfaces. Snoopy’s is not re-machined after fabrication, and therefore requires the clamp pressure for the two surfaces to conform and make a proper initial seal.</span></div>

<div class="MsoNormal"><span style="font-family:;">Finding a inside/outside hatch closure for Captain George's K-250 dome would be a real boon, in my view. It might not have to be quite Deepworker strong, as we aren't lifting the
Ks by their hats, so to speak. But we could definitely do with something more user friendly.</span></div>

and aaI have an archive of the Nekton construction drawings that I'm looking for a way to apreserve. If the legal end doesn't bite us, then I'm sure we can figure how to adapt proven technology to our requirements, and then provide the result with the K-plans

<div class="MsoNormal"><span style="font-family:; font-size: 10pt;">Agree strongly with Vance here, the standard K hatch is rubbish. If anyone wants to chip in any ideas for a "club design" i'm happy to make it over the winter.
I have a spare dish which was left over from the endcap hole II cut out. Its just the right size, dished and 13mm thick.</span></div>
