A MOB, short for Man Overboard Boat, is a small, fast rescue boat which large vessels, especially passenger ferries and cruise ships, use for man overboard situations. A MOB often has a RIB or similar hull to achieve great speed with stability. Both outboard engines and inboard pump-jet propulsion are used on MOB's. A MOB is required to be able to be launched and retrieved quickly, and is usually lowered with one wire.

  • Submarine


    underway in Groton, Connecticut, July 2004 A submarine (or simply sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term most commonly refers to a large, crewed vessel. It is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. The noun submarine evolved as a shortened form of submarine boat; by naval tradition, submarines are usually referred to as "boats" rather than as "ships", regardless of their size (boat is usually reserved for seagoing vessels of relatively small size). Although experimental submarines had been built before, submarine design took off during the 19th century, and they were adopted by several navies. Submarines were first widely used during World War I (1914–1918), and are now used in many navies large and small.
