The City of Norfolk—and many other ships like her on bays and rivers and lakes—is really a sort of combination ferry boat and hotel. Most ferries, of course, have much shorter runs, and they are built to fit the needs of their own special work.
Many ferries look exactly the same fore and aft. They have propellers, rudders and wheelhouses at both ends, and there’s a good reason why. A double-ended ferry makes quick trips back and forth. She can save time if she doesn’t have to turn around in the water when she goes in and out of her dock which is called a slip.
The big ferries carry automobiles, trucks, and as many as three thousand people at a time. Some of them, on long runs, have up-to-date snack bars so passengers can get quick meals. For safety, they carry lifeboats and life jackets, just as ocean-going vessels do. But a ferry could never go to sea. She is built very broad, with very little of her under the water and a great deal above. Big ocean waves would tip her over.
Men have used ferries from the earliest times. Hundreds and even thousands of years ago people and animals were ferried across rivers on rafts. Even today there are raft-like ferries which men guide across our rivers by steel cables.
Train ferries take loaded freight cars across harbors where there are no railroad bridges. In some harbors, the cars travel on flat-bottomed barges which tugboats shove along.
Long ago, barges were quite different. They were elegant vessels in which kings and important people travelled on rivers. And fancy barges, towed along behind paddle steamboats, once carried passengers up and down the Hudson River, too. At that time the steam boilers on paddleboats often exploded. Many crewmen and passengers were killed. So, in order to attract customers, some steamboats towed “safety barges” behind.
Nowadays barges are plain cargo vessels that do heavy work. Most of them have no power of their own. They must be towed or pushed. The seaman who handles a barge is called a barge captain. He must be an AB to get the job, and on some barges he lives in a house at the stern. If he has a family, they may make their home there the year round.
