A binnacle, which gets its name from the Latin "habitaculum" meaning "little dwelling place", is a sturdy, waist-high pedestal or housing built to hold and protect a ship's magnetic compass. It often features lighting for night viewing and holds adjustable iron spheres and magnets designed to cancel out interference from the ship's metal hull.
It stands on the bridge (right in front of the helm) so the captain and helmsman can constantly monitor the compass and keep the vessel on its proper heading.
2. Sextant
Answer: The Bridge
A sextant is a classic handheld navigation tool used to measure the angle between the horizon and a celestial body, like the sun or North Star. By calculating this precise angle alongside the exact time, sailors can determine their ship's position on the open ocean.
It's on the bridge, or the open bridge wings just outside, because navigator crew members need a clear, unobstructed view of both the sky and the sea horizon to take accurate readings.
3. Nautical chart
Answer: The Bridge
A nautical chart is a specialized map of a body of water that details water depths, underwater hazards, coastlines, and navigation marks like buoys and lighthouses. Unlike a standard road map, it gives sailors a complete view of the hidden ocean floor and maritime traffic lanes so they can chart a safe path. Officers on the bridge use this tool to track the vessel's live position and plan safe routes away from those shallow water or reefs.
4. Ship's wheel
Answer: The Bridge
A ship's wheel (or helm) is the primary mechanical or hydraulic steering device used to turn the vessel's rudder and change its direction through the water. Traditionally made of wood with spokes radiating from the hub, modern versions are often sleeker or use joystick controls, but they all serve that same core job of steering the ship.
It is usually positioned right at the helm station so the helmsman has a clear view ahead through the wheelhouse windows and can steer the ship according to the captain's directions.
5. Capstan
Answer: On Deck
A capstan is a heavy, vertical rotating drum used on ships to add pulling power when hauling massive lines or anchor chains. Traditionally operated by sailors pushing wooden bars in a circle around it, modern capstans are powered electrically or hydraulically to handle immense strain.
It is permanently mounted on the open deck (usually near the bow or stern) where sailors have the wide, clear physical space needed to manage heavy mooring cables and hoist anchors into or out of the water.
6. Cleat
Answer: On Deck
A cleat is a T-shaped fixture made of metal or heavy plastic that gives sailors a secure anchor point to tie off ropes and lines. By wrapping a rope around its two horns in a figure-eight pattern, friction holds the line tightly in place without requiring a knot that could get jammed under tension.
It is bolted directly to the open deck, especially along the outer edges and near the bow and stern, where crew members need immediate access to secure mooring lines to docks, fasten halyards, or tie down equipment.
7. Winch
Answer: On Deck
A winch is a mechanical spooling device with a crank or motor that winds heavy cable or rope around a rotating drum. It provides a mechanical advantage by allowing a small effort to pull, hoist, or hold thousands of pounds of tension. It is mounted directly to the open deck near the heavy machinery or mooring stations so crew members can easily haul in thick anchor lines, adjust heavy sail rigging, or pull the ship tight against a pier.
8. Halyard
Answer: On Deck
A halyard is a specialized line or rope used on a ship specifically to hoist objects upward, such as sails, flags, or signaling yards. The term comes from the old nautical phrase "haul yard," referencing the heavy wooden yards attached to the masts. It is rigged on the open deck, running up the length of the mast through pulleys, so sailors can easily raise, adjust, or lower sails and signal flags right from the deck floor.
9. Bilge pump
Answer: Engine Room
A bilge pump is a heavy-duty pump designed to collect and evacuate water that accumulates in the lowest internal compartment of a vessel, known as the bilge. Whether handling routine trickles from propeller seals or unexpected leakage, it ensures the ship remains dry and buoyant.
It is installed deep within the engine room, at the lowest point of the hull, where gravity naturally collects all runoff water and fluid, making it the most critical defense against flooding.
10. Propeller shaft
Answer: Engine Room
A propeller shaft is a long, heavy steel rod that transfers mechanical turning power from the ship's engine to the external propeller outside the hull. As the engine spins the shaft, it drives the propeller blades to push the vessel forward or backward through the water.
It runs directly through the lower engine room and shaft alley (which is the lowest, central spine of the vessel) to directly connect the engine's gearbox at one end to the propeller mounted outside the stern at the other.
11. Hydraulic pressure gauge
Answer: Engine Room
A hydraulic pressure gauge is an instrument designed to measure and display the fluid pressure running through a ship's powered machinery. It features a sealed display with real-time readings so engineers can monitor system health. It is mounted in the engine room, usually directly on hydraulic lines, steering units, and central control panels, where engineers can constantly check that vital systems like steering, pumps, and winches have enough pressure to operate safely.
12. Dipstick
Answer: Engine Room
A dipstick is a long, calibrated metal or plastic rod used to manually measure the liquid levels inside machinery reservoirs. By wiping it clean, reinserting it, and pulling it out, engineers can instantly check the oil or fluid mark against min/max indicators.
It is located in the engine room where it is inserted directly into the crankcases, oil sumps, and gearboxes of main propulsion engines and generators.
13. Gimbaled Stove
Answer: The Galley
A gimbaled stove is a specialized cooktop mounted on weighted, swiveling side pins that allow the entire unit to swing freely as the vessel rocks. Using gravity to counteract the motion of rough seas, it automatically tilts back and forth to keep hot pots, pans, and liquids perfectly level while cooking.
It is installed exclusively in the galley (the ship's kitchen) where it allows the ship's cook to safely prepare hot meals during choppy weather without boiling food or liquid spilling onto the floor.
14. Fiddle rails
Answer: The Galley
Fiddle rails (or sea rails) are raised wooden or metal lip borders fitted around the outer edges of countertops, tables, and shelves on a vessel. They act as physical guard barriers to catch plates, cookware, and prep tools before they can slide off flat surfaces when the ship rolls or pitches in rough seas.They are installed directly onto the tables, counters, and shelving throughout the galley.
15. Mess Tray
Answer: The Galley
A mess tray is a durable, compartmentalized food tray designed with deep sections to keep different foods separated. It is usually made of stainless steel or heavy plastic and its dividers prevent sauces, sides, and main dishes from sloshing together or spilling over the sides when the vessel rocks on the water.
It belongs in the galley and the mess hall where it provides crew members with a practical, unbreakable way to eat hot meals safely.
16. Cambro container
Answer: The Galley
A cambro container, or locking food pan, is a heavy-duty, commercial food container equipped with airtight, clamping lids and rubber gaskets. It's often found in the galley because it seals raw ingredients, prepped food, and liquids so tightly that nothing spills or leaks out, even if the container tumbles off a counter during heavy ocean swells.
