someone told me they thought this stopped sometime in the 1980's By that time it would mostly be cruise ships. When I visited the ships in dock in the 1960s it was mostly ocean liners although many of them did cruises in the winter. SS United States, the original QM (which I sailed on),the original Queen Elizabeth, the QE2, some of the smaller Cunard liners, the Rotterdam (HAL) and then the stunning new liner, the Hamburg. I remember the SS United States being so plain compared to these brass and red carpet beauties. Floors were linoleum and lots of stainless steel. Kind of like an American Diner
