'''Leeway''' is the amount of drift [[motion]] to [http://en.wikipedia.org/wiki/Leeward leeward] of an object floating in the water caused by the component of the [[wind]] [[vector]] that is [[perpendicular]] to the object’s forward motion. The National Search and Rescue Supplement to the International Aeronautical and Maritime Search and Rescue Manual defines leeway as "the movement of a search object through water caused by [[winds]] blowing against [[exposed]] surfaces". However, the resultant total motion of an object is made up of the leeway drift and the movement of the upper layer of the [[ocean]] caused by the surface currents, [http://en.wikipedia.org/wiki/Tidal_currents tidal currents] and [http://en.wikipedia.org/wiki/Ocean_currents ocean currents]. Objects with a greater [[exposure]] to each element will experience more leeway drift and overall movement through the water than ones with less exposure.

A [[navigator]] or pilot on a vessel must [[adjust]] the ordered [[course]] to compensate for the leeway drift and more important [http://en.wikipedia.org/wiki/Set_and_drift set and drift], an all [[encompassing]] term for drift that includes the steering error of the vessel.

An object can be [[classified]] as either an active object like a ship navigating through a waterway or a passive object like a liferaft, drifting debris, or a [[person]] in the water (PIW). A passive object will [[experience]] the greatest leeway drift and it is this drift that is of utmost importance to those involved in search and rescue (SAR) upon inland waterways and open [[oceans]].
