Now if you replace that with an identical section of acrylic, it will not work. To my mind the reason it will not work is, the acrylic will compress and the mass is no longer sufficient to carry the load along the load path into the hull. Now, if the acrylic is thicker, it will handle the pressure without failing and it can compress and have enough strength to carry the load to the frame . The window port frame need only transfer the force from the extra thickness into the load path. In short, to me, the port frame is only supporting the extra acrylic thickness and transferring the force into the hull. </span></div><div id="yui_3_16_0_ym19_1_1499126880347_22380"><span>Hank</span></div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 13px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"><font size="2" face="Arial"> On Monday, June 26, 2017 6:58 PM, james cottrell via Personal_Submersibles <personal_submersibles@psubs.org> wrote:<br></font></div> <br><br> <div class="y_msg_container"><div id="yiv8670007850"><div><div style="color:#000;background-color:#fff;font-family:verdana, helvetica, sans-serif;font-size:13px;"><div id="yiv8670007850yui_3_16_0_ym19_1_1498523979012_3052"><span id="yiv8670007850yui_3_16_0_ym19_1_1498523979012_3241">Here is a pic of Ron piloting the sub at 850 meters.</span></div><div dir="ltr" id="yiv8670007850yui_3_16_0_ym19_1_1498523979012_3052"><span><a rel="nofollow" shape="rect" target="_blank" href="http://ocean-innovations.net/OceanInnovationsNEW/Global%20Ocean%20Design/ont_part3_god.pdf">http://ocean-innovations.net/OceanInnovationsNEW/Global%20Ocean%20Design/ont_part3_god.pdf</a><br clear="none"></span></div><div id="yiv8670007850yui_3_16_0_ym19_1_1498523979012_3052"><span><br clear="none"></span></div><div dir="ltr" id="yiv8670007850yui_3_16_0_ym19_1_1498523979012_3052"><span id="yiv8670007850yui_3_16_0_ym19_1_1498523979012_4886">Ron told me that the rule about replacing the same amount of material removed from the viewport opening was wrong -"you need a hell of a lot more" were his exact words.
