Cruise Ship hits rough seas

QM2 max speed is 30kn
28.5kn "cruising" speed is highly unlikely.
17kn is a much more comfortable ride (depending on sea state) for a cruise ship

Speaking of lack of judgement of ship captains, I wonder if the recent reporting of navigation error that apparently allowed our 2 navy boats to wander into Iranian waters is attributed to human error rather than mechanical malfunction?

that answer would be highly political until it is getting FOIA'ed in about 50 years.

As trans Atlantic airlines slowly but surely put the trans Atlantic passenger liners out of business, some where converted to pleasure cruise ships. One of the conversions was to reduce engine power which naturally resulted in reduced cruising speeds. My understanding is that the primary reason for this particular modification was operational economy to allow them to compete in this market.

This is how things go wrong, very poor bridge team management procedures. I would love to hear the truth on the two navy ships...

yes,
combustion engines run most efficient somewhere between idle and 75% max throttle depending on seastate (i.e. 75% maybe with following winds and sea and stabilisers pulled in)
that is why i say 28.5kn cruising speed is some thick yarn ,)

Queen Mary Crusise speed is 24 kts. Not 28.5 like I said before although you will find that speed on the web as we.

From what I have read the QM2 is an overall tough boat designed for the Atlantic Ocean.
