Fore or forward: at or toward the front of a ship or further ahead of a location (opposite of "aft") [1] Preposition form is "before", e.g. "the mainmast is before the mizzenmast". Inboard: attached inside the ship. [14] Keel: the bottom structure of a ship's hull. [15] Leeward: side or direction away from the wind (opposite of "windward"). [16]
The draft survey is performed by reading the ship's draft on the draft markings at six standard points on the hull: forward, midships and aft on both port and starboard sides. [2] Corrections for factors such as trim, water density and non-cargo weight changes are made before calculating the cargo weight change.
For the most part, cruise ships, whether ocean or river, are divided into three sections: forward, or the front of the ship; midship, in the middle of the ship; and aft, or the back of the ship ...
The sheer forward is usually twice that aft. Increases in the rise of the sheer forward and aft build volume into the hull, and in turn increase its buoyancy forward and aft, thereby keeping the ends from diving into an oncoming wave and slowing the ship. In the early days of sail, one discussed a hull's sheer in terms of how much "hang" it had.
Graphical representation of the dimensions used to describe a ship. Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member.
4. : The left side of a ship or vessel when facing forward (formerly larboard). Denoted with a red light at night. [2] 5. Toward the left-hand side of the ship when facing forward (formerly "to larboard "). 6. : A sweep rower who rows with one oar on one side of a boat and primarily on the port (left) side of the boat.
Length between perpendiculars – The distance between where the forward part cuts the waterline and the rudder post of the ship. Length Overall (LOA) – The maximum length of the ship between the ship's extreme points; important for berthing purposes. Length at Waterline (LWL) – The ship's length measured at the waterline.
When the aft draft relative to the designed water line (DWL) is greater the vessel is deemed to have a positive trim, or to be trimmed by the stern, and it has a negative trim, or is trimmed by the bow, when the forward draft relative to DWL is the greater. [4] In such a case it may be referred to as being down-by-the-head. [citation needed]
