Re: M_Boats: Styrofoam in V berth storage

I did see an almost sunk container of the coast of Ft Lauderdale a few years back. it was drifting in the gulf stream about a foot out of the water, I heard it fell off a China container ship .. Hitting that in the darkness would be , well it might just ruin that evening? Apparently Asia vessels do not need or want to lock the containers together some how. That foam idea sounds like it would be the insurance against sinking if it would not take up the whole interior. Would air bladders work, like inflatable water tanks. How much boat can be float with each gallon container of air? any one know
