I added some ladder logic to my PLC that looked at the pitch angle of the boat when the MBT flood bottom was pushed. If the boat began pitching forward, the logic would close the forward MBT vet valve and if the boat were pitching backward, I would close the aft MBT vent valve. It did not work and I ended up deleting the option. What I found was this methodology aggravated the instability during MBT flooding. I think the best approach to have a stable MBT flooding event is what Alec is doing with Hugh Fulton's large port MBT vent valves. Of course it is always nice if the GB-GC split of the boat is large.<o:p></o:p></p></div><div><p class="MsoNormal"><o:p> </o:p></p></div><div><p class="MsoNormal">Cliff<o:p></o:p></p></div></div><p class="MsoNormal"><o:p> </o:p></p><div><div><p class="MsoNormal">On Sun, Oct 28, 2018 at 11:15 PM Alan via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<o:p></o:p></p></div><blockquote style="border:none;border-left:solid #CCCCCC 1.0pt;padding:0cm 0cm 0cm 6.0pt;margin-left:4.8pt;margin-right:0cm"><div><div><p class="MsoNormal">Hank,<o:p></o:p></p></div><div><p class="MsoNormal">you'll really get excited over this!
