Brad,

Paul's analogy works well here - as long as we are just talking about hydrostatic/hydrodynamic loading. If we introduce localized loading, like stepping into the boat while on-the-hard, or banging into stuff, the stress state can quickly change to a case more glass on the outside would be better. But since you don't feel sacrificial layers are important on the outside, we could ignore those types of localized loadings. In that case, the only extra glass that I might add is a patch inside each cockpit where the distributed local load from the paddler's seat causes bending, and associated compression on the inside.
