Interactive visualization of sailing positions relative to the wind
The point of sail describes a sailboat's direction relative to the wind. Understanding these positions is fundamental to sailing effectively.
A sailboat cannot sail directly into the wind. The area approximately 45° on either side of the wind direction is called the no-go zone. In this zone, the sails cannot generate lift, and the boat will stop or drift backward.
When sailing as close to the wind as possible (without entering the no-go zone), you're sailing close-hauled. The sails are pulled in tight, and the boat heels (tilts) significantly. This is how you sail upwind by "beating" back and forth.
A close reach is slightly off the wind from close-hauled. The sails are eased out a bit, and the boat begins to accelerate as it finds a better angle to the wind.
The beam reach is when the wind comes directly from the side of the boat (perpendicular to the hull). This is often the fastest and most comfortable point of sail. The sails are set at roughly 45° to the centerline.
On a broad reach, the wind comes from behind and to the side. The sails are let out far, and the boat can achieve good speed with a comfortable motion.
When sailing with the wind directly behind you, you're running. The sails are let out as far as possible. While this seems simple, running can be tricky because the wind pressure is directly pushing the boat rather than creating aerodynamic lift.
A boat is on starboard tack when the wind comes over the starboard (right) side, and on port tack when the wind comes over the port (left) side. Under racing rules, a boat on starboard tack has right-of-way over a boat on port tack.
