  1. Basic Seamanship - Basic Shipboard Knowledge

  2. How to board a military ship ensign • 1. Walk half way up the gangplank, turn to the rear or stern and salute the ensign. • 2. Once up the plank, ask permission to come aboard and also when leaving, to go ashore.

  3. BOAT TERMS AND NOMENCLATURE Boat crew members often develop the habit of calling objects and the activities around them by their proper names. In times of emergency, your understanding and correct response to such terms could save valuable time. .

  4. The floors of a ship are called decks, the walls are called bulkheads, and the stairs are called ladders. There are no halls or corridors in a ship, only passageways. There are no ceilings in a room, only the overhead in the compartment. Openings in the outside of the ship are ports, not windows. Entrances from one compartment to another are called doors. Openings from one deck to another are called hatches. The handles on the watertight hatch or door are called dogs.

  5. Abaft - Any part of the boat aft of amidships. After end (aft) - The after end (aft) of a boat is the stern.

  6. Amidships - Amidships is a point about halfway between the bow and stern and the sides of the boat. Athwartships - When something is said to be Athwartships it’s across the boat from side to side. Forward end (fore) - The forward end (fore) of the boat is the bow.

  7. Inboard - Inboard usually describes the area inside the boat or an object nearer the centerline of the boat. Outboard - Outboard describes the area furthermost from the boat’s centerline or beyond the side of a boat.

  8. Starboard - When facing forward of the boat, your right-hand side is the starboard. Port - When you are facing forward of the boat, your left-hand side is the port.

  9. STRUCTURAL PARTS OF THE HULL The hull is the main body of the ship below the main outside deck. The hull consists of an outside covering (or skin) and an inside framework to which the skin is secured. The skin and framework are usually made of steel and secured by welding. However, there may still be some areas where rivets are used. The steel skin may also be called shell plating.

  10. The main centerline structural part of the hull is the keel, which runs from the stem at the bow to the sternpost at the stern. The keel is the backbone of the ship. To the keel are fastened the frames, which run athwartship. These are the ribs of the ship and gives shape and strength to the hull. Deck beams and bulkheads support the decks and gives added strength to resist the pressure of the water on the sides of the hull.

  11. Weather Decks The decks aboard ship are the same as the floors in a house. The main deck is the first continuous watertight deck that runs from the bow to the stern. In many instances, the weather deck and the main deck may be one and the same. Any partial deck above the main deck is named according to its location on the ship. At the bow it is called a forecastle deck, amidships it is an upper deck, and at the stern it is called the poop deck. The term weather deck includes all parts of the forecastle, main, upper, and poop decks exposed to the weather. Any structure built above the weather deck is called superstructure.
