If you think of mobility scooters; they have a </div><div>range of 30 miles on a 55 ah battery.</div><div>would be cool to be able to beach launch a sub.</div><div>Alan</div><div><br><br>Sent from my iPad</div><div><br>On 24/07/2014, at 11:51 pm, hank pronk via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="color:#000; background-color:#fff; font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12pt"><div>Alan,</div><div>The fellow that helps me test and dive my subs is a huge fan of tracks on a sub. We debate this for hrs after a big struggle at a lake trying to launch. This idea would be the ultimate system. The problem is, if it were electric, the power consumption would be huge and put a big drain on your batteries. I figured the only way to do it would be with a gas motor hyd power pack. Hook up the quick connectors to launch, then disconnect. The next problem is, tracks, even rubber, are very heavy. The setup could weigh 1,000 lb easily if it is carrying a sub. Then there is the cost, think big! :-) It would be the ultimate though!</div><div>Hank</div></div></div></blockquote><blockquote type="cite"><div><span>_______________________________________________</span><br><span>Personal_Submersibles mailing list</span><br><span><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span><br><span><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a></span><br></div></blockquote></body></html>
