A long narrow centreboard produces less drag than a short, wide one for a given amount of lift, resulting in a faster boat that can point closer into the wind. A fore and aft, pivoting centreboard can also be used to move the centre of lateral resistance aft to match a change in sail plan, such as furling or dropping the jib.
Since the steering oar was on the right side of the boat, it would tie up at the wharf on the other side. Hence the left side was called port. [6] The Oxford English Dictionary cites port in this usage since 1543. [7] Formerly, larboard was often used instead of port. This is from Middle English ladebord and the term lade is related to the ...
Lift and drag are components of the total aerodynamic force on sail (F T). Since the forces on the sail are resisted by forces in the water (for a boat) or on the traveled surface (for an ice boat or land sailing craft), their corresponding forces can also be decomposed from total aerodynamic force into driving force (F R) and lateral force (F ...
A yaw motion is a side-to side movement of the bow and stern of the ship. The transverse/Y axis, lateral axis, or pitch axis is an imaginary line running horizontally across the ship and through the centre of mass. A pitch motion is an up-or-down movement of the bow and stern of the ship.
Only the leeward side leeboard is used at any time, as it submerges when the boat heels under the force of the wind. A disadvantage, where there is an inadequate fixed keel, is that they typically ship (bear) little ballast, which being on the far side delays the onset of unballasted craft's heeling, that is, to put up a good, constant ...
Tacking or coming about is a sailing maneuver by which a sailing craft (sailing vessel, ice boat, or land yacht), whose next destination is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction.

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.
