Exactly how Jim describes Snoopy. I hoisted myself out of the water over one of Gamma's saddle tanks while Hank was sitting on the CT, and the sub had no real roll tendency. Perhaps a pair of saddle tanks forward and another pair aft would solve it. You should expect that transitioning through the air-water interface while submerging and surfacing is when roll (and pitch) stability is the greatest challenge.</span><span style='font-size:10.0pt;font-family:"Arial",sans-serif'><o:p></o:p></span></p></div><p><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US'>Tim</span><o:p></o:p></p><p> <o:p></o:p></p><p><b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Personal_Submersibles [<a href="mailto:personal_submersibles-bounces@psubs.org">mailto:personal_submersibles-bounces@psubs.org</a>] <b>On Behalf Of </b>hank pronk via Personal_Submersibles<br><b>Sent:</b> Thursday, April 14, 2016 2:14 PM<br><b>To:</b> Personal Submersibles General Discussion <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>><br><b>Subject:</b> Re: [PSUBS-MAILIST] more Esmae video</span><o:p></o:p></p><p> <o:p></o:p></p><p style='background:white'><span style='font-size:9.0pt;font-family:"Helvetica",sans-serif;color:black'>Brian,</span><o:p></o:p></p><p style='background:white'><span style='font-size:9.0pt;font-family:"Helvetica",sans-serif;color:black'>Vance is dead right! don't cut into your MBT yet.

When he added side ballast tanks to Snoopy, I asked why he had mounted them so they were partially above the waterline when surfaced. He explained that when the vessel rolls to one side, the tank on that side then becomes more submerged and provides more "lift." Simultaneously the tank on the other side rises and provides less lift. The net effect is automatic roll dampening.</span><o:p></o:p></p><p style='background:white'><span style='font-family:"Arial",sans-serif;color:black'>Jim T.</span><o:p></o:p></p><p style='background:white'> <o:p></o:p></p><p style='background:white'> <o:p></o:p></p><p style='background:white'><span style='font-size:10.0pt;font-family:"Arial",sans-serif;color:black'>In a message dated 4/14/2016 9:18:04 A.M.
