- 39. Runs along the centreline at the bottom of the ship and may form part of the backbone of the ship;
- 40. A mount to which equipment is attached to transfer a load to the ships structure. Often connecting heavy equipment (such as engines) to their structural foundations.
- 43. The width of the hull at its widest point.

- 58. Ship length between its furthest points, bow to stern,
- 59. the wash left over after a wave breaks on the deck,
- 60. A longitudinal course of plating in the deck,
- 61. The upper edge of a hull,
- 62. A collection of blocks put together to form a part of a ship. ie a number of bow blocks are put together to make the bow.
- 64. Where the hull of a ship meets the surface of the water,
Down
- 1. The tube under the hull bearing the tail shaft for propulsion,
- 3. Length between forward and aft perpendiculars,
- 4. The middle of the ship, wither longitudinally or laterally.
- 5. The lean of a vessel to one side or the other from the vertical usually caused by manoeuvring.
- 8. The area on the outer surface of a ship's hull where the bottom curves to meet the vertical sides.
- 9. Frame of heavy scantling used in ship construction and made by Welding a wide plate to a frame and stiffening the plate.
- 11. Framing parallel to the keel along the bottom shell or deck,
- 12. The raised edge of a hatch, cockpit or skylight
- 13. The distance from the waterline to the upper deck level, measured at the lowest point of sheer, where water can enter the boat or ship.
- 15. The portion of the space within a ship defined vertically between decks and horizontally between bulkheads,
- 16. Perpendicular to centerline and are evenly spaced between the aft perpendicular (AP) and the forward perpendicular (FP)
- 17. Upright wall that separates parts of a ship; can be load bearing (structural) or non-load bearing (partition); can be watertight or non-watertight,
- 23. The variance between fore and aft draft of a ship,
- 24. Vertical distance measured from the bottom of the keel to the top of the freeboard deck, typically main deck or weather deck,
- 25. A vessel’s angle of lean or tilt to one side in the direction called roll (caused by flooding or improperly loaded or shifted cargo).
- 26. The number markers on each side of a ship at the bow,
- 30. The anticipated defined water line that intersects the side shell of a ship at max load capacity; also known as the design waterline,
- 32. When something is capable of preventing the passage of water in any direction.,
- 35. The extension of the ship’s side above the level of the weather deck,
- 36. The underside of the deck above,
- 38. A large iron or steel beam or compound structure used for framework,
- 41. Provide added support to bulkhead and other structures;
- 42. these are holes left in frames to allow movement of water so it doesn’t become entrapped,
- 44. A partial deck above the upper deck and at the head of the vessel,
- 45. Facing the bow or forward, everything right of centerline,
- 48. Leads the flow of waste fluids towards the bilge wells on either side of the vessel,
