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.
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.
The assignment of freeboard (and therefore applicable load line) is dependent on the: type of ship [1] structure of the ship [1] areas and seasons the ship trades in, eg winter North Atlantic [1] other safety measures for special conditions, including certain cargoes. [1] Ships are also categorised as either a type A ship or a type B ship.
Uses and requirements [ edit ] For US waters, the US Code of Federal Regulations require ships and their masters to calculate UKC based on the ship's deepest navigational draft. 33 CFR 157.450 The regulations require the master to discuss the UKC calculation with the maritime pilot as the ship approaches US ports/waters. 33 CFR 157.450
A freeboard is a specialist skateboard designed to closely simulate the behavior of a snowboard. Freeboards were developed to allow snowboarders to transition to skateboarding (as non-winter transport) without the need to adapt to a smaller deck and narrower wheel -base.

Used mainly to determine the minimum water depth for safe passage of a vessel and to calculate the vessels displacement (obtained from ships stability tables) so as to determine the mass of cargo on board. Draft, Air – Air Draft/Draught is the distance from the water line to the highest point on a ship (including antennas) while it is loaded ...
