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.
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 ...
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".
Jibe – Basic sailing maneuver, where ship turns its stern through the wind Tacking (sailing) – A sailing maneuver Translation (physics) – Planar movement within a Euclidean space without rotation Pages displaying short descriptions of redirect targets
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.
Shipping was one of the earliest channels of commerce, and rules for resolving maritime trade disputes were developed early. An ancient example was the Rhodian law (Nomos Rhodion Nautikos), of which no extensive written specimen has survived, but which is alluded to in other legal texts (Roman and Byzantine legal codes), and later the customs of the Consulate of the Sea and the Hanseatic League.

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 ...
