But if your going real deep then chances are it will be lowered into the water from a boat or barge, so need for the swivel. If I end up being less ambitious, and build an Elementary 7,500 I will do just that.</span><span style='font-family:"Helvetica",sans-serif;color:black'><o:p></o:p></span></p></div></div><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499630532547_3250"><div><p class=MsoNormal style='background:white'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:black'>Hank</span><span style='font-family:"Helvetica",sans-serif;color:black'><o:p></o:p></span></p></div></div><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499649104847_10187"><div style='margin-bottom:12.0pt'><p class=MsoNormal style='background:white'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:black'> </span><span style='font-family:"Helvetica",sans-serif;color:black'><o:p></o:p></span></p></div></div><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499631641198_3678"><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499631641198_3677"><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499631641198_3676"><div id="yiv6377084832m_-8062362793588594983yiv0466071481yqt89970"><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499631641198_3675"><div><p class=MsoNormal style='background:white'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:black'>On Sunday, July 9, 2017 1:57 PM, james cottrell via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs. org</a>> wrote:</span><span style='font-family:"Helvetica",sans-serif;color:black'><o:p></o:p></span></p></div></div><div style='margin-bottom:12.0pt'><p class=MsoNormal style='background:white'><span style='font-family:"Helvetica",sans-serif;color:black'> <o:p></o:p></span></p></div><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499631641198_3681"><div id="yiv6377084832m_-8062362793588594983yiv0466071481"><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499631641198_3680"><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499631641198_3679"><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499629315211_3150"><div><p class=MsoNormal style='background:white'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:black'>Hank,</span><span style='font-family:"Helvetica",sans-serif;color:black'><o:p></o:p></span></p></div></div><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499629315211_3150"><div><p class=MsoNormal style='background:white'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:black'> </span><span style='font-family:"Helvetica",sans-serif;color:black'><o:p></o:p></span></p></div></div><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499629315211_3150"><div><p class=MsoNormal style='background:white'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:black'>I was thinking that it might be possible to mount a sphere within a steel frame that allows it to swivel up and down like a gun turret in a bomber. That way, the forward viewport could be incorporated into the hatch and the hatch/ port could be in the "up" position to get in and out and then in the "down" position during the dive for viewing. All internal components could be mounted on an internal frame that hangs from a bearing so that the pilot is always upright. The main ballast system could be a pair of port/ starboard pontoons.</span><span style='font-family:"Helvetica",sans-serif;color:black'><o:p></o:p></span></p></div></div><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499629315211_3150"><div><p class=MsoNormal style='background:white'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:black'> </span><span style='font-family:"Helvetica",sans-serif;color:black'><o:p></o:p></span></p></div></div><div id="yiv6377084832m_-8062362793588594983yiv0466071481yui_3_16_0_ym19_1_1499629315211_3150"><div><p class=MsoNormal style='background:white'><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif;color:black'>For a shallow diving sub, the hatch/ port could be a large dome for good viewing.
