MOLDED_DEPTHThe vertical distance from the molded baseline to the top of the freeboard deck beam at side, measured at midlength of the ship 
CBBlock coefficient  a measure of the fullness of the form of the ship and is the ratio of the volume of displacement to a given waterline, and the volume of the circumscribing solid of constant rectangular crosssection having the same length, breadth and draught as the ship. CB= (L x B x T) The LPP is normally used in calculating the value of CB which varies with the type of ship. Fast ships Ordinary ships Slow ships 0.500.65 (fine form) 0.650.75 (moderate form) 0.750.85 (full form)

PENDANT

DRAG

BALLASTAny liquid or solid weight placed in a ship to change the trim, increase the draft, or to regulate the stability 
SCOPEThe ratio of length of anchor rode in use to the vertical distance from the bow of the vessel to the bottom of the water. Usually six to seven to one for calm weather and more scope in storm conditions. 
LPPThe length of a vessel along the waterline from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. Believed to give a reasonable idea of the vessel's carrying capacity, as it excludes the small, often unusable volume contained in her overhanging ends. 
FLUSH DECK SHIPA ship constructed with upper deck extending throughout her entire length without a break or a superstructure, such as forecastle, bridge or poop
