<div dir="ltr">I have to say one thing I wonder about is the function of that rear spoiler. It certainly makes the vessel look more like a race car, but can anyone think whether it actually serves a purpose? All I can think is that because she's got positive buoyancy, the spoiler forces the boat under when there's forward motion. It doesn't look like the spoiler pivots, and it would seem cumbersome to make the down-force a function of forward velocity. <div><br></div><div>Best,</div><div><br>Alec</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Nov 18, 2015 at 10:58 PM, Alan James 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><div style="color:#000;background-color:#fff;font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;font-size:16px"><div><div><div style="background-color:rgb(255,255,255)"><div style="color:rgb(0,0,0);font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:16px"><span>Hi Tim,</span></div><div dir="ltr" style="color:rgb(0,0,0);font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:16px"><span>yes it would be difficult to get in to that in anything other than a mill pond;</span></div><div dir="ltr" style="color:rgb(0,0,0);font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:16px"><span>& I wonder about the stability also; the way the bouyancy seems to be placed low down.</span></div><div dir="ltr" style="color:rgb(0,0,0);font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:16px"><span>From the videos I've seen it looks like the hatch can only be opened from the outside,</span></div><div dir="ltr" style="color:rgb(0,0,0);font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:16px"><span>could be wrong though.</span></div><div dir="ltr" style="color:rgb(0,0,0);font-family:HelveticaNeue,'Helvetica Neue',Helvetica,Arial,'Lucida Grande',sans-serif;font-size:16px"><span>The large diameter thrusters look like they could be made from bike hub motors.

From underwater fighter jets to this underwater race car. I noticed that there is no photo showing ingress/egress on the surface. Personal submarines, in my humble opinion, really should have sufficient freeboard (often a conning tower) to allow the pilot to operate the vessel solo (without a launch crew and/or crane).
