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 ...
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°
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 ...
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 ...
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.
A turn of 32 points is a complete turn through 360 degrees. point up. Also head up. To change the direction of a sailboat so that it is more upwind, i.e. to bring the bow windward. This is the opposite of falling off. Points of sail and approximate apparent wind for a conventional sailboat on starboard tack points of sail
