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 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 forces transmitted via the sails are resisted by forces from the hull, keel, and rudder of a sailing craft, by forces from skate runners of an iceboat, or by forces from wheels of a land sailing craft which are steering the course. This combination of forces means that it is possible to sail an upwind course as well as downwind.
For many sailing craft 45° on either side of the wind is a no-go zone, where a sail is unable to mobilize power from the wind. Sailing on a course as close to the wind as possible—approximately 45°—is termed beating, a point of sail when the sails are close-hauled. At 90° off the wind, a craft is on a beam reach.
Seamanship on a commercial level involves a knowledge of all the different ship types (such as bulk carriers, container ships, oil tankers, cruise ships, platform supply vessels, and others), including a basic knowledge of ship recognition, a basic understanding of nautical terms, ship structure and naval architecture and cargo operations ...

Sail components include the features that define a sail's shape and function, plus its constituent parts from which it is manufactured. A sail may be classified in a variety of ways, including by its orientation to the vessel (e.g. fore-and-aft) and its shape, (e.g. (a)symmetrical, triangular, quadrilateral, etc.).
A backstay is a piece of standing rigging on a sailing vessel that runs from the mast to either its transom or rear quarter, counteracting the forestay and jib. It is an important sail trim control and has a direct effect on the shape of the mainsail and the headsail .
