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. The point of sail between beating and a beam reach is called a close reach. At 135° off the wind, a craft is on a broad reach.
Garrett demonstrates how those diagrams translate into lift and drag, for a given sail, on different points of sail, in diagrams similar to these: [33] Polar diagrams, showing lift ( L ), drag ( D ), total aerodynamic force ( F T ), forward driving force ( F R ), and lateral force ( F LAT ) for upwind points of sail
English: Points of sail. The arrow represents the direction of the wind. The red is the "no sail zone" because it is impossible to sail into the wind. A. No Go Zone — 0-30° B. Close Hauled — 30-50° C. Beam Reach — 90° D. Broad Reach — ~135° E. Running — 180°
Points of sail: the shaded area is the "no-sail" zone. Beating to windward on short (P1), medium (P2), and long (P3) tacks, each with a progressively wider corridor over the water. Sails are limited in how close to the direction of the wind they can power a sailing craft. The area towards the wind defining those limits is called the "no-sail zone".
The points of sail clarify the realities of sailing into the wind. One of the points of sail is "Head to Wind." A boat turns through this point on each tack. It is the point at which the boat is neither on port tack or starboard tack and is headed directly into the wind. However, a boat cannot sail directly into the wind, thus if it comes head ...
All sailing craft reach a constant forward velocity (V B) for a given true wind velocity (V T) and point of sail. The craft's point of sail affects its velocity for a given true wind velocity. Conventional sailing craft cannot derive power from the wind in a "no-go" zone that is approximately 40° to 50° away from the true wind, depending on ...
Sailing is the use of wind to provide the primary power via sail(s) or wing to propel a boat. To help improve sailing related articles, please feel free to join WikiProject: Sailing See also: Category:Age of Sail
Sailing – the use of wind to provide the primary power via sail(s) or wing to propel a craft over water, ice or land. A sailor manages the force of the wind on the sails by adjusting their angle with respect to the moving sailing craft and sometimes by adjusting the sail area.
