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.
The physics of sailing arises from a balance of forces between the wind powering the sailing craft as it passes over its sails and the resistance by the sailing craft against being blown off course, which is provided in the water by the keel, rudder, underwater foils and other elements of the underbody of a sailboat, on ice by the runners of an ...

It is an art because of the skill that the navigator must have to avoid the dangers of navigation, and it is a science because it is based on physical , mathematical , oceanographic , cartographic ...
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.
The course sail is the lowermost sail. In sailing, a course is a type of square sail. It is the sail set on the lowest yard on a mast. The courses are given a name derived from the mast on which they are set, so the course on the foremast may be called the fore-course or the foresail; similarly main-course or mainsail for that carried on the ...
The traditional Olympic triangle course consists of a lap (starting with a beat or work to windward from the starting line to the top, weather or windward mark, a first reaching leg to the wing mark (also known as the gybe mark), a second reaching leg from the wing mark to the bottom or leeward mark), a hot dog (a beat to the top mark with a square run back to the bottom mark), another lap and ...
