What's that going to do to a deck not designed for it? The technical term is buckle it to b8ggery. Never mind the damage it does to the deck crews who have to be in proportionally closer proximity.
Word from friends who work at Rosyth was that it was a concern even with CVF. Lack of suitable deck paint being mentioned.
