“Points of sail” are names for your boat’s course in relation to the wind. Imagine your boat at the centre of a clock, with the wind coming from 12 o’clock. Pointing at 12 puts you in the no-go zone; if the boat stops there, it is in irons. Around 1:30 you are close-hauled, with the sails pulled in tight. At 2 you are on a close reach, at 3 a beam reach, and at 4:30 a broad reach. The sails ease farther out at each step. At 6, with the wind directly behind you, you are on a run, with the mainsail all the way out. The same names apply on either side of the clock.
If you have ever looked up at a sail and wondered, “Should that be pulled in or let out?”, the wind angle gives you a starting point. Sailors call each course relative to the wind a point of sail. The name depends on where the wind comes from, not on your speed or the kind of boat.
Picture the boat at the centre of a clock, with the wind blowing from 12 o’clock. As the bow turns around the clock, you move through close-hauled, close reach, beam reach, broad reach, and run. Point straight toward 12 and the boat cannot sail; if it stops there, it is in irons.
You will learn to match each name with what you see and feel: sails pulled tight, then eased farther out, until they are all the way out downwind.
Put the Wind at the Top: A Points of Sail Clock
At first, sail trim can feel like guesswork. How far should the sails be out? Then you notice the pattern: every wind angle has a name, and each name suggests a sail position.
Picture the boat at the centre of a clock. Put the wind at 12 o’clock. The bow is the clock hand. Points of sail name where the bow points relative to that wind—not the boat’s speed or type.
Near 1:30, you are close-hauled, with the sails tight. You may feel wind on your face and see the telltales—small strips on the sail—streaming back. Around 2 is a close reach. At 3 comes a beam reach, then a broad reach near 4:30. As the bow turns away from the wind, you ease the sails out bit by bit.
At 6, you are on a run. The wind comes from behind, the mainsail is all the way out, and the boat may heel less but roll more. Think: flatter, quieter, wind on your back.
At 12, the boat cannot sail directly into the wind. It may stop in irons—a condition, not a course you sail. The same point names repeat on the other side, including beam reach at 9 and broad reach near 7:30.
At 12 O’Clock: In Irons
Picture the wind arriving from the top of the clock. When the bow points straight toward 12, it points directly into the wind. A sailboat cannot sail on this heading. Rather than calling it a usable point of sail, sailors say the boat is in irons.
You can recognize this state by watching the sails and the boat. The sails lose their smooth, curved shape and begin to flap. This is called luffing. Even if you pull the sails in, they cannot stay filled while the bow points directly into the wind.
With no useful drive from the sails, the boat slows and may stop. It can also begin moving backward if it remains there. That stalled feeling—and the sound and movement of flapping sails—tells you that the bow is at the top of the clock. As the boat points away from 12 and reaches a usable wind angle, the sails can take shape again.
Around 1:30 and 2 O’Clock: Close-Hauled and Close Reach
Around 1:30, you are close-hauled. This is the closest usable course to the wind. The sails are pulled in tightly, near the centre of the boat. You may notice the wind clearly on your face.
Look at the telltales: small strips of yarn or fabric attached to a sail. When the sail is trimmed well, the telltales on both sides stream aft. They give you a simple visual check that air is flowing smoothly over the sail.
Now let the bow bear away, or turn farther from the wind, toward about 2 o’clock. You move onto a close reach. The wind arrives less directly from ahead, so you ease the sails out slightly rather than keeping them tight.
The clock positions are a memory aid, not fixed measurements. Different boats can sail close to the wind at different angles. The pattern stays useful: close-hauled means tight sails; close reach means you have turned away a little and eased them a little.
At 3 and 4:30: Beam Reach and Broad Reach
At about 3 o’clock, the wind crosses the side of the boat at a right angle. This is a beam reach. The side is called the beam, which gives this point of sail its name. Look for two simple clues: the bow points across the wind, and the sails sit roughly halfway out.
Now turn the bow farther away from the wind, toward 4:30. This is called bearing away. As the bow changes direction, you ease the sheets—the lines that control the sails—so the sails open farther from the boat.
At 4:30, you are on a broad reach. The wind now comes from behind the side of the boat, but not from directly behind. The sails are well out, though not yet as far as they will be on a run.
Watch the pattern rather than chasing an exact clock position: as the bow turns away from 12, the sails open step by step. Halfway out suggests a beam reach. Farther out, with the wind arriving from behind the side, suggests a broad reach.
At 6 O’Clock: Running Downwind
At the bottom of the sailor’s clock, the boat points directly away from the wind. This point of sail is called a run, or running downwind. The wind arrives over the stern, meaning the back of the boat, and the mainsail is let all the way out.
If you face forward, you may notice the wind on your back rather than your face. The boat can also feel flatter and quieter than it did while sailing closer to the wind. Sideways force has reduced, and the sail now catches the wind more like a parachute than a wing.
Look at the whole clock-face pattern: the sails were tight near the top, then eased farther out through each reach. At 6 o’clock, that progression is complete. The wind is directly behind you, the mainsail is fully out, and your course has a simple name: a run.
Once you picture the wind arriving from 12 o’clock, the points of sail become a simple way to name your course by its angle to that wind—not by your speed or boat type. Near the closest sailable angle, you feel wind on your face and see the telltales, small strips on the sail, streaming back. As your bow turns away from the wind, you ease the sails farther out, step by step. With the wind directly behind you, the sails are fully eased and a run can feel flatter and quieter, with the wind on your back. If you turn too far toward 12, the bow points into the wind, the boat stalls, and it may not turn; sailors call this being “in irons.” To practice recognizing these cues, try SailStarter’s short Points of Sail beginner lesson.
