<div dir="ltr">This is interesting because the K350 and K250 have virtually the same design in this respect, but I can't induce this problem even on purpose. If I flood one tank 100% and only then start flooding the other, so that the boat feels like she's standing on her head, I still don't get a bubble block. Well... no complaints! But I'm looking at it carefully because I'm following the K design on the new boat as its worked well for me.<div><br></div><div>Best,<br><br>Alec </div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jul 30, 2015 at 4:44 PM, Hugh Fulton via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="EN-US" link="blue" vlink="purple"><div><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Hi James,<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">I had a similar problem with the Comsub.
