1.1: MEASUREMENT OF SHIP<br />Length over All:<br />,[object Object]
 This length is an important dimension of the ship when docking.Length between Perpendicular:<br />,[object Object]
The aft perpendicular is the after side of the rudder coast.
The center of the rudder stem if there is no rudder coast.
 Distance between these two point is known as the length between perpendicular and its used for ship construction.Draft:<br />,[object Object]
It is the measurement of the under water from the water line to the bottom of the keel that is called draft of the vessel.
It is the important part of the ship, the draught of the ship will be measured where the maximum portion of the hull is in water.
This is the draft extreme when the distance from the bottom of the keel to the water line.Width:<br />,[object Object]
It is also called beam.  Beam is the maximum breadth or width of the vessel.
Generally the beam of a ship fishing vessel will be toward the mid ship.
It may also depend the design aspects of the vessel.Depth Extreme:<br />,[object Object],Depth Molded:<br />,[object Object]
This is called depth molded.Keel:<br />,[object Object]
The Keel is located in the center line of the bottom structure, which often said to be backbone of the ship.
This contribute substantially to the longitudinally strength and effectively distribute local loading caused when docking the ship.
The commonest form of the keel is that known as the flat plate keel and this is fitted in the majority of ocean going and other vessels.
A form of keel found on smaller vessels known as bar keel.

  • 3. The aft perpendicular is the after side of the rudder coast.
  • 4. The center of the rudder stem if there is no rudder coast.
  • 5.
  • 6. It is the measurement of the under water from the water line to the bottom of the keel that is called draft of the vessel.
  • 7. It is the important part of the ship, the draught of the ship will be measured where the maximum portion of the hull is in water.

  • 15. The commonest form of the keel is that known as the flat plate keel and this is fitted in the majority of ocean going and other vessels.
  • 16. A form of keel found on smaller vessels known as bar keel.
  • 17.
  • 18.
  • 19. The space between the bottoms is for the storage to fuel, or ballast water.
  • 20. Double bottom design ships are safer than single bottom.
  • 21. A double bottom hull design the second layer extends up to the side of the ship and in the bottom.
  • 22.
  • 23. When facing the star board side is on the right hand and port side is on the left.
  • 24. The curved shape of the ships is called the bow and the curved shapes after part is called as amid ship.
  • 25. When a ship is float or in the water line it divides the size into ships side above the water line and bottom below it.
  • 26. These terms are used in general way for example: Painting ship site.
  • 27. The continuous horizontal surface of a ship is called decks.
  • 28.
  • 29. Aft all bulk heads.
  • 30.
  • 31. One outer layer forming the normal hull of the ship and second inner hull which is somewhat higher in the ship perhaps a few feet.
  • 32. The space between the bottoms is for the storage for fuel, or ballast water.
  • 33. Double bottom design ships are safer than single bottom.
  • 34. A double bottom hull design the second layer extends up to the side of the ship and in the bottom.
  • 35.
  • 36. A part of its always submerged below the water surface depending upon its weight.
  • 37. If the water level goes above the plimsol line it is considered dangerous and the ship sinks.
  • 38. It is a line of mark on a ship’s hull indicating the maximum safe draft.
  • 39. It is a mark on the hull of ship that shows where the water line is when the ship is at full capacity.
  • 40. The official name is by the International load line and it is painted on each of the vessel.
  • 41. The symbol is also international load line of plimsol line marks and it shows the level to which the ships can be safely loaded.
  • 42. The plimsol line shows how know or high the ship is resting in water.
  • 43. It is also called load line or International load line.
  • 44. The level of the ship is the water attended by temperature and salinity as well as load and so different levels are shown with code letters to indicate the type of water.
  • 45. It is marked amid ship on each side of vessel.
  • 46. The plimsol line helps as to determine whether the ships have been over loaded.
  • 47. The plimsol line mark was introduced in great Brittan through MS act, 1875 and soon found world wide acceptance.
  • 48.
  • 49. The bottom shell may be transversely or longitudinally framed.
  • 50. The side shell framing may also be transversely or longitudinally framed, transverse framing being adopted in many conventionally cargo ships, particularly where the maximum bale capacity is required Longitudinal framing may be adopted in larger container ships and larger bulk carriers, and it is common within the hopper and topside wing tanks of the latter vessels.
  • 51. Transverse frames are then fitted at the side shell between the hopper and topside tanks.
  • 52. Ocean – going tankers have a longitudinally framed bottom shell and deck through the tank spaces.
  • 53.
  • 54. Longitudinal frames are usually numbered from the deck downwards to the keel.
  • 55.
  • 56. Let us now describe the movements of a seaman who is returning to his ship, the ship in which he is borne.
  • 57. If he arrives by boat be goes up an accommodation ladder which is secured outboard, he comes over the side and he is then on board.
  • 58. If the ship is lying against a dock wall it is alongside and the seaman crosses a brow (fore head) from the dock to the ship and he is then on board and on deck, or on board and between deck if the brow leads into the ship below the weather deck; in either case he is inboard the moment he come over the side.
  • 59. Having reported his return, he then goes below by a ladder which given access to the deck below through an opening in the deck called a hatch.
  • 60.
  • 61. The ensign staff is right aft and the jack (devise for raising heavy objects) staff right forward.
  • 62. A hatch is amid ships.
  • 63. Amidships describes the position roughly in the middle of the ship; it also describes any position on the fore and aft line.
  • 64. Mid ships is used when defining an object: for example, the mid ship hatch is either the one that is in middle of the ship or, if there are two more hatches, that which is nearest the middle .
  • 65.
  • 66. The center line divides the ship into port and starboard, while the ship’s sides give an inboard and outboard position.
  • 67. For example, a ship is carrying three boats; one is swing outboard to port, the other two are stowed inboard to starboard.
  • 68. When comparing the position of the two boats stowed on the starboard side, the black boat can be described as lying inboard of the white boat, or the white boat outboard of the black.
  • 69. The white boat can also be described as the ship’s side boat and the black boat as the mid ship boat.
  • 70.
  • 71. He uses the same expressions for shifting an object; thus he may shift something aft, or farther forward, to port or starboard, or nearer the ship’s side.
  • 72. The terms inboard and outboard should not be used to describe the movement athwart ships.
  • 73. The following terms are used to describe how an object is moved:
  • 74. To launch is to drag or heave an object along.
  • 75. To lift and launch is to drag or heave an object and then to heave it along.
  • 76. To fleet is to shift an object a short distance.
  • 77. To ship is to place an object in its proper position.
  • 78.
  • 79. It is the measurement of the under water from the water line to the bottom of the keel that is called draft of the vessel.
  • 80. It is the important part of the ship, the draught of the ship will be measured where the maximum portion of the hull is in water.
  • 81.
  • 84.
  • 86.
  • 87.
  • 88.
  • 89. That particular department is called deck department.
  • 90. The captain or the master of the ship of in charge of the ship.
  • 91. He is not only responsible for the safe navigation of the vessel but also the discipline of the ship, and also safety of passenger, crew and cargo.
  • 92. The captain is assisted by first mate, second mate and third mate.
  • 93. The first mate is the right hand man to the captain.
  • 94. He is the second in command.
  • 95. He oversees all the cargo planning, assist during navigation, allocated duties, work.
