That sounds hairy, Vic, well done.

Re the Louis Majesty:
The photos on the link below show what happened to the St.Christopher during the 1987 hurricane. The big vertically-sliding steel door at the forward end of the upper car deck was stowed in by a particularly heavy sea coming over. This is in just the same position as the lounge windows on the Louis Majesty, straight off the forecastle, and this is what can happen to an immensely strong steel door let alone some toughened glass windows. When the first of the Maersk D's was about to commence her voyage to the UK from the builders in Korea, the MCA debated whether to insist on the panoramic windows in the Bridge front being plated over for the voyage and they are a long way above the forecastle deck level.

Re freak waves:
Going back to when I was deepsea, I recall an extraordinary calamity befalling the Ben Line fast cargoship Bencruachan on her way to/from the Far East around the Cape. Again not really due to a freak wave but a set of circumstances well known around the South African coast due to a combination of the Agulhas current, the seabed configuration at the continental shelf, the Cape rollers (giant swells sweeping unrestrained around the world at the top of the Southern Ocean), local weather conditions and the ships speed. These can all come together to create what amounts to a sudden great hole in the ocean down into which the ship slams with immense force. The entire forward end of the Bencruachan for about a quarter of the length of the ship was bent down and to starboard, leaving her like a giant banana. She was eventually repaired and put back into service.
