CROSS-SECTIONS SHIPS
Cruise Ships Today’s cruise ships are floating resorts with many activities for their passengers.The passengers can socialize on deck, cool off in a swimming pool, go dancing, or play tennis. Some ships even have ice-skating rinks and rock-climbing walls!

Queen Mary, was 1,019.5 feet long and had four 35-ton
propellers. The ship traveled only 13 feet for every gallon
of fuel it burned.
