The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed. [1] [2] [3] [page needed] The path that a vessel follows is called a track or, in the case of aircraft, ground track (also known as course made good or course over the ground). [1] The intended track is a route.
True course is 120°, the Variation is 5° West, and the Deviation is 1° West. T: 120° V: +5° M: 125° D: +1° C: 126° Therefore, to achieve a true course of 120°, one should follow a compass heading of 126°. True course is 120°, the Variation is 5° East and the Deviation is 1° East. T: 120° V: −5° M: 115° D: −1° C: 114°
Course made good (C.M.G. or Course Over Ground) - the actual route taken to achieve the journey's objecting measured over the ground. It is the resultant of the course steered and the effect on that course of any wind and tide. Sail trim - pulling the sail in when sailing upwind and letting it out when sailing downwind.
This motion is generated directly either by the water and wind motion, particularly lateral wave motion, exerting forces against the hull or by the ship's own propulsion; or indirectly by the inertia of the ship while turning. This movement can be compared to the vessel's lateral drift from its course.
Navigation (from the Latin word navigatio) is the act of sailing or voyaging.Nautical (from Latin nautĭca, and this from Greek ναυτική [τέχνη] nautikḗ [téjne] "[art of] sailing" and from ναύτης nautes "sailor") is that pertaining to navigation and the science and art of sailing.
Depending on the angle of the true wind with respect to the course sailed, a reach may be close, beam, or broad, as follows: A close reach is a course closer to the true wind (more upwindwards) than a beam reach, but below close-hauled; i.e., any angle between a beam reach and close-hauled. The sails are trimmed in (hauled towards the ...

Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the water (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ice or on land over a chosen course, which is often part of a larger plan of navigation.
