Re: Prince of Wales
I think they miscalculated the loading on the prop shaft mountings - so one/several sheered and had to be re-done and of course strengthened. Which came up during full speed sea trials - the reason you muck about doing sea trials for so long with new classes of ship.
However both ships were the opposite of cut in half. They are modular built (5 or 6 sections from memory?) - then the modules have been glued together. Or it might have been done with gaffer tape?
