Re: [PSUBS-MAILIST] Center of gravity Vs. Center of Bouyancy

Adam,

OOPS!  I've gotta qualify my previous statement.  I agree with Ed's
description of CG (below), except that you should understand that the sub's
not actually hanging in mid air, but floating in the water at neutral
buoyancy.  (Wouldn't want you to confuse CG with CW.)  Check out SUB MATH,
it will explain what I mean.

VBR,

Pat
