Merchant ships operate in three basic ways: as liners on regular routes with published timetables, sailing whether full or not; as tramps without regular routes or timetables, carrying cargo wherever available; or as specialized vessels designed for particular cargo types.
2. MERCHANT SHIPS ARE DESIGNED TO CARRY
CARGO. SOME ARE ALSO DESIGNED TO CARRY
PASSENGERS. NOWDAYS MOST MERCHANT
SHIPS ARE BUILT TO CARRY CARGO. A FEW
STILL CARRY PASSENGERS. MERCHANT
VESSELS CAN OPERATE IN THE FOLLOWING
THREE BASIC WAYS.
3. THEY CAN OPERATE AS LINERS. LINERS
ARE EMPLOYED ON REGULAR ROUTES ON A
FIXED TIMETABLE. A LIST OF THEIR
ARRIVAL AND DEPARTURE DATES IS
PUBLISHED IN ADVANCE. THEY SAIL
WHETHER THEY ARE FULL OR NOT.
4. MERCHANT VESSELS CAN ALSO OPERATE AS
TRAMPS. TRAMPS DO NOT SAIL ON REGULAR
ROUTES. THEY DO NOT KEEP TO A FIXED
TIMETABLE. THEY ARE EMPLOYED IN ALL PARTS
OF THE WORLD WHERE THERE IS CARGO FOR
THEM TO CARRY.
5. A LARGE NUMBER OF MERCHANT SHIPS
OPERATE AS SPECIALIZED VESSELS. THESE ARE
DESIGNED TO CARRY A PARTICULAR TYPE OF
CARGO.
