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.
