2.  Is the room or platform from which the ship can be commanded. When a ship is underway the bridge is manned by an OWO (officer of the watch) aided usually by an AB (able seaman) acting as lookout. During critical maneuvers the captain will be on the bridge supported, perhaps, by an OOW as an extra set of hands, an AB on the wheel and sometimes a pilot if required.

3.  Is a glass disk mounted in a window that rotates to disperse rain, spray, and snow. A clear view screen is typically driven by an electric motor at the center of the disk, and is often heated to prevent condensation or icing.

4.  are the small enclosed parts of a bridge which historically held the ship's steering wheel. Today, ship bridges do not have a separate wheelhouse. In some cases, the term wheelhouse is used interchangeably to refer to the bridge.

5.  Is a rail that is designed to be grasped by the hand so as to provide stability or support.

6.  placed to communicate the bridge with the front deck.

7.  Designed to be thrown to a person in the water, to provide buoyancy, to prevent drowning. Some modern lifebuoys are fitted with one or more seawater-activated lights, to aid rescue at night.

8.  A post or pair mounted on the ship's bow, for fastening ropes or cables.

9.  A large winch with a vertical axis. A full-sized human-powered capstan is a waist-high cylindrical machine, operated by a number of hands who each insert a horizontal capstan bar in holes in the capstan and walk in a circle. Used to wind in anchors or other heavy objects; and sometimes to administer flogging over.

10.  The front of a vessel; either side of the front (or bow) of the vessel, i.e., the port bow and starboard bow. Something ahead and to the left of the vessel is "off the port bow", whiles something ahead and to the right of the vessel is "off the starboard bow." When "bow" is used in this way, the front of the vessel sometimes is called her bows (plural).

11.  Means a white light on the centerline of the vessel showing from right ahead to 22.5 degrees abaft the beam on either side of the vessel.

12.  Is a tall spar, or arrangement of spars, erected more or less vertically on the centre- line of a ship or boat. Its purposes include carrying sail, spars, and derricks, and giving necessary height to a navigation light, look out- position, signal yard, control, radio aerial or signal lamp. Large ships have several masts, with the size and configuration d.

13.  Is a visual signaling device for optical communication. Modern signal lamps are a focused lamp which can produce a pulse of light. In large versions this pulse is achieved by opening and closing shutters mounted in front of the lamp, either via a manually operated pressure switch or, in later versions, automatically. With hand held lamps, a concave mirror is tilted by a trigger to focus the light into pulses.

14.  Smokestack or chimne y on a ship used to expel boiler steam and smoke or engine exhaust. They are also commonly referred to as stacks.

15.  Is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the “tension" of a rope or wire rope (also called "cable" or "wire cable").

16.  Is a nautical term for a thick cable or rope used in mooring or towing a ship.

17.  The main deck of a ship is the uppermost complete deck extendi ng from bow to stern.

18.  A small door in a wall, floor or ceiling used to gain access to equipment is called an access hatch or access door.

19.  is the top edge of the side of a boat.

20.  Is a bumper used to absorb the kinetic energy of a boat or vessel berthing against a jetty, quay wall or other vessel. Fenders are used to prevent damage to boats, vessels and berthing structures.

21.  Is a device used to steer a ship, boat,, or other conveyance that moves through a medium (generally air or water).

22.  It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter.

23.  Is a type of fan that transmits power by converting rotational motion into thrust.

24.  Is a mechanical component for transmitting torque and rotation, usually used to connect other components of a drive train that cannot be connected directly because of distance or the need to allow for relative movement between them.

25.  Is the water thigh body of a ship or boat. Above the hull are the superstructure and/or deckhouse, where present. The line where the hull meets the water surface is called the waterline.
