 Graham,Your new pods are 150 lbs more buoyant that the original, so your 150 lbs lead will be very close.  This is assuming the battery weight is the same for both pods.  Hank

Hi

my name is Graham Bayliss I  have been building Casper 2 for many years and now find my self frustrated by science I have craned my sub into the water three time only to be frustrated by buoyancy problems I have redesigned my battery tubes to carry more batteries. this has meant they are very buoyant and being on the bottom my boat they tend to want to turn her on her side. My housings measure six feet long by fourteen inches I can not calculate how much weight I need to make these negative buoyancy I have three leisure batteries in each housing plus one hundred and fifty pound of lead on top. this does not counteract the upforce which each housing is subjecting my sub to. I am lost as to how I can over come my problem  as  she is determined to roll . can some one help me please.

regards

Graham

Pictures  of Casper 2 being built are on the site if you need to look at what I have built.
