That’s more for comfort than anything I would think, a modern cruise ship can easily take pretty insane storms? They have active stabilization systems and huge amounts of mass while still powered by relatively strong engines?
replyCan they handle rogue waves?
replyAlthough, I guess rogue waves can appear anywhere deep and rough.
Right. The S.S. United States was built for winter North Atlantic conditions,
with a power plant, hull, and watertight compartments more like a warship than a cruise ship. She could be converted to a troop carrier if necessary, something that had been done to big liners during WWII. Cruising speed 30MPH, top speed 44MPH.
Great for getting across the Atlantic in 3 1/2 days. Not so great on fuel economy.
replyCruise ships today look like hotels mounted on barges [1]. About half the speed. A refurbished SS United States was never going to compete in that market, and plans to do so were never funded.
