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.
