Re: [PSUBS-MAILIST] Odd Idea

The thing with submarines is that you WANT to be able to lose 
your positive buoyancy to submerge and then refill your ballast 
tanks with air to regain your positive buoyancy to surface. Foam in 
small fishing boats is a good idea to prevent sinking the boat 
completely but with subs you WANT to be able to sink. (Hopefully 
temporarily)
