Maybe pour the lead to the contour</div><div>of the bottom & add syntactic foam around the conning tower.</div><div>With the height of the conning tower that would improve your</div><div>centre of buoyancy. Tritons top pilot told me he liked to dive as quick</div><div>as possible due to the instability issues that Vance described with</div><div>the CG & CB changing. you may find that you aren't so top heavy</div><div>once the conning tower is under. Perhaps you could attach a rope</div><div>around the conning tower next attempt & limit any roll just in case.</div><div>Cheers Alan <br><br>Sent from my iPad</div><div><br>On 15/04/2016, at 2:17 am, Brian Cox via Personal_Submersibles <<a href="mailto:personal_submersibles@psubs.org">personal_submersibles@psubs.org</a>> wrote:<br><br></div><blockquote type="cite"><div><div style="font-family:Arial, sans-serif; font-size:10pt;"><div>Hi Alan, Going to add a lot of weight to the bottom of the concrete ballast , at the very bottom.
