In sailing and boating, a vessel's freeboard is 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. [1] In commercial vessels, the latter criterion measured relative to the ship's load line , regardless of deck arrangements, is the mandated and regulated meaning.
Freeboard deck: assigned by a classification society to determine the ship's freeboard; usually the highest continuous deck, i.e. equivalent to the main deck. Gun deck : ( naval ) on a multi-decked vessel, a deck below the upper deck where the ships' cannon were carried. [ 3 ]
Except for the timber winter North Atlantic freeboard, the other freeboards are less than the standard freeboards. This allows these ships to carry additional timber as deck cargo, but with the facility to jettison this cargo. The letters on the timber load line marks have the following meanings: LTF – timber tropical fresh water
Lightweight displacement – LWD – The weight or mass of the ship excluding cargo, fuel, ballast, stores, passengers, and crew, but with water in the boilers to steaming level. Loadline displacement – The weight or mass of the ship loaded to the load line or plimsoll mark. Deadweight tonnage (DWT) is a measure of how much weight a ship can ...
The ship was 492 ft 0 in (149.96 m) overall, 465 ft 0 in (141.73 m) between perpendiculars, with a beam of 69 ft 6 in (21.18 m). She had a depth of 33 ft 6 in (10.21 m) at the freeboard deck, 42 feet 6 inches (12.95 m) at the shelter deck and a draught of 28 ft 7 7 ⁄ 16 in (8.72 m).

A ship will sink if the transverse bulkheads are so far apart that flooding a single compartment would consume all the ship's reserve buoyancy. Aside from the possible protection of machinery, or areas most susceptible to damage, such a ship would be no better than a ship without watertight subdivision, and is called a one-compartment ship.
This additional mass will also reduce freeboard (distance from water to the deck) and the ship's downflooding angle (minimum angle of heel at which water will be able to flow into the hull). The range of positive stability will be reduced to the angle of down flooding resulting in a reduced righting lever.
