If you prefer multi-hull then try the Wharram tiki hull design. Both brilliant in what they could do. The monohull landing craft is more roadable depending on dimensions.</span></div><div class="yiv5806910384MsoNormal"><span style="font-size:11.0pt;">Tim</span></div><div class="yiv5806910384MsoNormal"><span style="font-size:11.0pt;"> </span></div><div class="yiv5806910384yqt2494978353" id="yiv5806910384yqt34225"><div><div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in;"><div class="yiv5806910384MsoNormal"><b><span lang="EN-US" style="font-size:11.0pt;">From:</span></b><span lang="EN-US" style="font-size:11.0pt;"> Personal_Submersibles [mailto:personal_submersibles-bounces@psubs.org] <b>On Behalf Of </b>hank pronk via Personal_Submersibles<br clear="none"><b>Sent:</b> Wednesday, June 14, 2017 6:11 PM<br clear="none"><b>To:</b> Personal Submersibles General Discussion <personal_submersibles@psubs.org><br clear="none"><b>Subject:</b> [PSUBS-MAILIST] landing craft</span></div></div></div><div class="yiv5806910384MsoNormal"> </div><div><div id="yiv5806910384yui_3_16_0_1_1497488281118_2683"><div class="yiv5806910384MsoNormal" style="background:white;"><span style="font-size:10.0pt;">Hi All,</span></div></div><div id="yiv5806910384yui_3_16_0_1_1497488281118_2683"><div class="yiv5806910384MsoNormal" style="background:white;"><span style="font-size:10.0pt;">Got a problem to solve, my sub barge has a 30 hp outboard motor. When I try to cruise fast it cavitates real bad. When I push something that won't move like a dock, I can push at full throttle no problem. I am planning to build a landing craft 36 feet long using the steel hull from my paddle wheeler. I am building it to carry and launch Elementary. My concern is, because it is a displacement hull and it will be slow, will I have the same problem with cavitation that the barge has. Do I need to use a jet instead? I can't work on it for a year, but I want to source all the parts, engine, drive etc etc.</span></div></div><div id="yiv5806910384yui_3_16_0_1_1497488281118_2683"><div class="yiv5806910384MsoNormal" style="background:white;"><span style="font-size:10.0pt;">Hank</span></div></div></div></div></div></div></div><div class="yqt2494978353" id="yqt28553">_______________________________________________<br clear="none">Personal_Submersibles mailing list<br clear="none"><a shape="rect" ymailto="mailto:Personal_Submersibles@psubs.org" href="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br clear="none"><a shape="rect" href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br clear="none"></div><br><br></div> </div> </div> </div></div></body></html>
