Would some one be please be kind 
    enough to look this over for me? If I were to be correct with these numbers 
    it would mean some advancement in grasping of the basics.
     
    Submerged displacement    = 28,637 lbs
    Minus vessel dry weight     - 10,000 
    lbs
    Variable ballast required       18,637 
    lbs = 2,330 gallons of seawater in tanks
     
    Cubic feet of ballast tanks required = 291 cf required to reach 
    theoretical neutral buoyancy.
     
    Does this appear viable?
     
    Thanks
     
    Joe
