One cubic foot of air displaces one cubic foot of water (compression notwithstanding). A cubic foot of water weighs 62lbs. I think you're vastly underestimating the bouyancy of an inflated bag. Try to pull a standard birthday party balloon underwater. It's nearly impossible to do. You would need a tremendous amount of extra weight to submerge a goatskin full of air.
