A double, or triple, beavertail may be sufficient to roll the sub off into sufficiently deep water. Rather than rollers on the trailer, perhaps rollers on the sub's skids that would then match up with gutter tracks on the beavertail and trailer bed? At least one psub out there has rollers on its skids. The skids should also have a ski-tip on each end to allow the winch to drag the sub through the mud-sand substrate to launch and recover.</span></div><div><span style="font-size: 11pt;">Tim</span></div><div><span style="font-size: 11pt;"> </span></div><div><div><div style="border-width: 1pt medium medium; border-style: solid none none; border-color: rgb(225,

[PSUBS-MAILIST] sub launch<br />Date: Sun, 16 Oct 2016 16:18:43 +0000 (UTC)</span></div><div><div><div><div style="background: white;"><span style="font-size: 9pt;">Hi all,</span></div></div><div><div style="background: white;"><span style="font-size: 9pt;">I have been pondering the age old problem of launching in shallow water. I am making new fibreglass MBT's for Gamma in a few weeks or so, I will increase the diameter to give me more free board. The steel tanks are a bit to heavy and could use more volume. Also the thruster tubes will be vectored in the new tanks.</span></div></div><div><div style="background: white;"><span style="font-size: 9pt;">But that will only help with launching in shallow water a bit. I am thinking that typically the water is deep enough for the sub alone without the trailer. So my plan is to install an A frame on the trailer that can lift the sub when it is backed into the water. The sub is light at this point, so
lifting it off the trailer is easy and then the A frame tilts back dragging the sub off the trailer. To load the sub, just drive it up to the back of the trailer and hook the cable to the lifting eye, then tilt the A frame forward, it lifts the sub and drags it onto the trailer. I figure I will need a roller on the end of the trailer to help the sub slide ahead.</span></div></div><div><div style="background: white;"><span style="font-size: 9pt;">Easy Peezy</span></div></div><div><div style="background: white;"><span style="font-size: 9pt;">Hank</span></div></div></div></div><div style="background: white;"><span style="font-size: 10pt;">_______________________________________________ Personal_Submersibles mailing list <span><a href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a></span> <a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a>
