Freeboard or freeboard is the vertical distance

Freeboard or freeboard is the vertical distance between the surface of the water and the main deck of a ship, the edge , measured at any point on the side. On merchant marine vessels , freeboard is measured from the waterline , regardless of deck arrangements . [ 1 ] [ 2 ] [ 3 ] [ 4 ] Competition yachts often have a reduced freeboard, with the aim of reducing weight and consequently increasing speed. On the other hand, a high freeboard will allow for greater interior space in the vessel. [ 1 ] [ 2 ] [ 3 ] [ 4 ] A high freeboard also helps to cope with waves and reduce water entry onto the main deck. A vessel with reduced freeboard is likely to take on water in rough seas. [ 1 ] [ 2 ] [ 3 ] [ 4 ] Freighters and warships use high freeboard designs to increase internal volume and to make them comply with International Maritime Organization damage stability regulations due to increased buoyancy reserve. Freeboard or freeboard is the vertical distance between the surface of the water and the main deck of a ship, the edge , measured at any point on the side.
