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.
The top of a triangular sail, the head, is raised by a halyard, The forward lower corner of the sail, the tack, is shackled to a fixed point on the boat in a manner to allow pivoting about that point—either on a mast, e.g. for a mainsail, or on the deck, e.g. for a jib or staysail.
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 ...
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 ...
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.
Velocity made good, or VMG, is a term used in sailing, especially in yacht racing, indicating the speed of a sailboat towards (or from) the direction of the wind. [1] [2] The concept is useful because a sailboat cannot sail directly upwind, and thus often can not, or should not, sail directly to a mark to reach it as quickly as possible.
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
