[PSUBS-MAILIST] Esmae close up 2

[hank pronk via Personal_Submersibles]

 Alan,You may be underestimating the air volume in the main MBT.  I also predicted the sub would  do a nose dive suddenly, but that was before the addition of the new light weight second MBT up front.  There is enough MBT above the water line when most of the sub is submerged.  I think Brian has it, pity he couldnt de a test dip.Hank

 Hi Brian,I am not going to win a popularity contest here, but it looks likeyou are going to need a ton more lead & maybe build an extra ballast tankaround the spherical portion! It seems way too high out of the water.If you consider the volume & weight that you have above the water line; is that equalto the volume of air that you have in your ballast tanks? I.e. when the air is releasedis it going to be neutrally buoyant?It also looks like the ballast tank end will pivot downward from the sphericalportion when the air is released, & you will have the submarine on a steep angle.You would need a lot of lead in the bottom of the sphere.I had to rebuild my ballast tanks & add a lot more lead to my sub, but it isnowhere near the size of yours!Would like to know what the opinion of other Psubbers is as I am open tocriticism on this!Cheers Alan

HI All,                      Here's an enlarged pic of Esmae at dock,  unfortunately I didn't take any video or too many pictures.   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.   Brian
