Points of Sail
Understanding your angle relative to the wind
The No-Go Zone and Close-Hauled
No sailboat can sail directly into the wind. The zone roughly 45° either side of the wind direction is called the no-go zone (or in irons). If you try to sail into it, the sails luff, the boat stalls, and you lose steerage.
Close-hauled is the closest angle to the wind at which a boat can sail efficiently — about 30–45° off the wind. Sails are pulled in tight. This is the most technically demanding point of sail, requiring precise helm and trim to maintain speed.
When sailing close-hauled upwind toward a destination that's directly into the wind, sailors tack back and forth in a zigzag pattern — a technique called working to windward or beating.
On close-hauled, ease the mainsheet until the luff just starts to flutter, then trim back in just enough to stop it. That's your optimal trim.
What is the 'no-go zone'?
When sailing close-hauled, how should the sails be trimmed?
Reaching: Close, Beam, and Broad
Reaching is the general term for sailing with the wind coming from the side. There are three types: close reach (wind from slightly forward of the beam, 60–80° off the wind), beam reach (wind from directly abeam, ~90°), and broad reach (wind from behind and to the side, 110–160° off the wind).
The beam reach is where most boats are fastest and most comfortable. Sails are about halfway out. The boat is sailing at its best angle of attack — enough pressure without too much heel.
On a broad reach, sails are let out most of the way. Speed is good, but as you approach a dead run, the risk of an accidental gybe increases. Watch the wind angle carefully.
As you bear away from a beam reach toward a broad reach, ease both the mainsheet and jib sheets progressively. The sails should always be just on the edge of luffing — any tighter and you're over-trimmed; any looser and you're wasting power.

Running: Sailing Downwind
A run (or dead run) is when the wind is coming from directly behind the boat — 180° off the bow. The mainsail is let all the way out on one side, and the jib can be poled out to the opposite side in a configuration called wing-on-wing.
Running is slower than reaching for most boats and requires extra vigilance. The boat tends to roll or wallow without the stabilizing pressure of wind on the sails. Small steering corrections can easily lead to an accidental gybe.
On a run, apparent wind drops dramatically — the boat is moving with the wind, reducing the relative airflow across the sails. In light conditions this can make it feel like there's no wind at all, even at boat speeds of 5–6 knots.
When running, consider using a spinnaker or gennaker — purpose-built downwind sails that capture the wind more effectively than the mainsail and jib alone.
Never sail a dead run in heavy air without an experienced crew. An accidental gybe in strong winds can cause serious injury and damage. In doubt, sail a broad reach and gybe deliberately when ready.
What is 'wing-on-wing' sailing?
Why does apparent wind feel lower on a dead run than on a beam reach in the same true wind?
Changing Points of Sail
Heading up means turning toward the wind (toward the no-go zone). As you head up, pull sails in progressively. Bearing away (falling off) means turning away from the wind toward a run. As you bear away, ease sails out progressively.
When you cross the wind from one side to the other going upwind, you tack. When you cross the wind from one side to the other going downwind, you gybe. Both maneuvers result in the wind coming from the opposite side.
A well-executed course change always involves coordinating helm and sail trim simultaneously — the helm turns the boat while the crew adjusts sheets at the same rate.
Helmsperson calls 'Bearing away!' and pushes the tiller to windward (or turns the wheel toward the wind). At the same moment, the crew eases the mainsheet and jib sheets as the boat turns away from the wind. The transition should be smooth, with the sails on the verge of luffing throughout the turn.
You are on a beam reach and head up. What should happen to your sails?
You are sailing downwind and wish to switch the wind from port to starboard. What maneuver is required?
Summary
The points of sail, closest to furthest from the wind: no-go zone, close-hauled, close reach, beam reach, broad reach, running.
Boats cannot sail directly into the wind — the no-go zone is approximately 90° wide, 45° on each side.
The beam reach is typically the fastest point of sail. The run requires the most caution due to accidental gybe risk.
Heading up requires trimming sails in. Bearing away requires easing sails out. Always coordinate helm and trim together.
