I am encouraged by the use of carbon fibre in Ocean Gates new sub. I bought them on Ebay of coarse, so I saved thousands of dollars. I am getting 1260 lbs NET buoyancy for 1,90 dollars per lb This increased amount of buoyancy will allow me to make E3000 a two person sub. The added benefit will be increased stability and improved transitioning from surfaced to submerged. The original added buoyancy requirement was 550 lbs, so you can see the benefits to having 1260 lbs to work with.</div><div>Hank</div><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:13px;"></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>
