Kind of a mixed bag of good and bad. When we dropped it in the water it floated just where I had hoped it would. and was quite stable. I have some problems with the concrete hull in that I have a bunch of small leaks around the edges where I have bolt penetrations , those leaks make it so the ballast starts taking on water , I thought I had addressed those leaks earlier but no. So then we decided that I might as well see where I'm at with the ballast totally flooded, started flooding the ballast and it soon became apparent that the side to side stability could be a problem. I was on the conning tower trying to make the thing tip over and I'm pretty sure if I kept at is I could have done so. So I need to address that . I came in at around 7 tones . Once I process the video I'll post a link. But with all things considered I'm happy to know where I'm at least. Getting in down to the harbor and back on the trailer was an accomplishment in it self !</div><div id="yui_3_16_0_ym19_1_1459820760457_2505"> </div><div id="yui_3_16_0_ym19_1_1459820760457_2498">Brian</div></div></div><br>_______________________________________________<br>Personal_Submersibles mailing list<br><a id="yui_3_16_0_ym19_1_1459820760457_2734" href="mailto:Personal_Submersibles@psubs.org" ymailto="mailto:Personal_Submersibles@psubs.org">Personal_Submersibles@psubs.org</a><br><a href="http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles" target="_blank">http://www.psubs.org/mailman/listinfo.cgi/personal_submersibles</a><br><br><br></div> </div> </div> </div></div></body></html>
