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. At 180° off the wind (sailing in the same direction as the wind), a craft is running downwind. [1] A given point of sail (beating, close reach, beam reach, broad reach, and running downwind) is defined in reference to ...
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°
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 ...
The diagram seems to imply that point of sail is relative to the true wind, but the text is silent. For instance, this excerpt: "...a boat cannot sail directly into the wind. Instead, a boat sails at various angles to the wind the closest of which is about 45 degrees... The point of sail closest to the wind is close-hauled.
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
The diagram is also symmetrical, implying (incorrectly) that the rotor ship can sail equally as well into the wind as downwind. Andy Dingley ( talk ) 09:47, 14 October 2015 (UTC) [ reply ] Original Source
A polar diagram, or polar plot, is a graph that shows a sailboat's potential speed over a range of wind speeds and relative wind angles. [1] It normally consists of the right side of a line chart with the radius representing the yacht speed and the angle representing the wind direction blowing from top to bottom.
A sail plan is a drawing of a sailing craft, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. [1] By extension, "sail plan" describes the arrangement of sails on a craft. [2] [3] A sailing craft may be waterborne (a ship or boat), an iceboat, or a sail-powered land vehicle.
