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 ...
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 ...
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 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.
The direction that the craft is traveling with respect to the true wind (the wind direction and speed over the surface) is called the "point of sail". The speed of the craft at a given point of sail contributes to the apparent wind (V A), the wind speed and direction as measured on the

The jib is backed to windward, the mainsail is slightly eased, and the rudder is fixed in an attempt to turn into the wind (which is coming from the top of the diagram). In sailing , heaving to (to heave to and to be hove to ) is a way of slowing a sailing vessel's forward progress, as well as fixing the helm and sail positions so that the ...
