But you can see a little better how it sits in the water. The fact that I didn't get a chance to submerge is really starting to bug me now! I still have some unanswered questions, namely if there would still be air in my main ballast when fully submerged. </div><div> </div><div>Brian</div><div> </div><div> </div></div></div></blockquote><blockquote type="cite"><div><Close-up-2.jpg></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>
