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.
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.
For many sailing craft, the arc spanning 45° on either side of the wind is a "no-go" zone, [44] where a sail is unable to mobilize power from the wind. [45] Sailing on a course as close to the wind as possible—approximately 45°—is termed "close-hauled". At 90° off the wind, a craft is on a "beam reach".
Integrated over the sailing craft, the total aerodynamic force (F T) is located at the centre of effort (CE), which is a function of the design and adjustment of the sails on a sailing craft. Similarly, the total hydrodynamic force ( F l ) is located at the centre of lateral resistance ( CLR ), which is a function of the design of the hull and ...
An extract from a case study in the application of Mark Room (Rule 18). The Racing Rules of Sailing (often abbreviated to RRS) govern the conduct of yacht racing, windsurfing, kitesurfing, model boat racing, dinghy racing and virtually any other form of racing around a course with more than one vessel while powered by the wind.
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 ...
