The five essentials of sailing describes the five key things that a dinghy sailor uses to sail the boat as efficiently as possible. The five essentials are: [ 1 ] [ 2 ] [ 3 ] Boat balance - which side the sailor sits on and how far out to make sure the boat sails level.
A sailing vessel heels when the boat leans over to the side in reaction to wind forces on the sails. A sailing vessel's form stability (derived from the shape of the hull and the position of the center of gravity) is the starting point for resisting heeling. Catamarans and iceboats have a wide stance that makes them resistant to heeling.
A sail is a tensile structure, which is made from fabric or other membrane materials, that uses wind power to propel sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and even sail-powered land vehicles. Sails may be made from a combination of woven materials—including canvas or polyester cloth, laminated membranes or ...
A sailing craft is said to be sailing close-hauled when its sails are trimmed in tightly and are acting substantially like a wing, relying on lift to propel the craft forward on a course as close to the wind as the sail can provide lift. This point of sail lets the sailing craft travel upwind, diagonally to the wind direction. [4]
Marine navigation is the art and science of steering a ship from a starting point (sailing) to a destination, efficiently and responsibly. 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 ...
A sailing ship is a sea-going vessel that uses sails mounted on masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships , employing square-rigged or fore-and-aft sails.

Spar (sailing) – pole of wood, metal or lightweight materials such as carbon fibre used in the rigging of a sailing vessel to carry or support its sail. These include booms and masts, which serve both to deploy sail and resist compressive and bending forces, as well as the bowsprit and spinnaker pole.
