Quick answer
Points of sail describe the boat's heading relative to the true wind: in irons (0°, no-go), close-hauled (~45°), close reach (~60°), beam reach (90°), broad reach (~135°), and run (180°, dead downwind). The no-go zone spans roughly 45° on either side of the wind, where sails luff and the boat won't drive forward.
The no-go zone (in irons)
Sailboats cannot sail directly into the wind. The arc roughly 45° on either side of the eye of the wind is the no-go zone — try to point there and the sails flap like flags, the boat slows, and you drift sideways. Modern performance boats can pinch to about 30°, classic cruisers more like 50°.
To get somewhere upwind of you, you tack: zig-zag back and forth across the no-go zone, sailing close-hauled on each leg. Each tack adds distance but it's the only way upwind — the wind doesn't negotiate.
If you accidentally end up head-to-wind with no momentum, you're 'in irons.' Push the tiller hard over and back the jib (hold it to the windward side) to swing the bow off the wind, then trim and sail away.
Close-hauled
The closest you can sail to the wind without luffing — about 45° off the true wind for a cruising boat. Sails are sheeted in tight, the boat heels noticeably, you feel pressure on the helm, and apparent wind is at its strongest.
This is the workhorse point of sail when you need to make ground upwind. Watch your headsail telltales: both flying horizontally means you're sailing the boat at its best angle. If the windward telltale luffs, bear off slightly; if the leeward one stalls, head up.
The reaches
Close reach (~60° off wind): faster than close-hauled, more comfortable, sails eased a touch. Beam reach (90°, wind directly on the side): the fastest, easiest, most exhilarating point of sail for most boats — flat water, full power, easy steering. Broad reach (~135°): wind over the quarter, sails eased well out, downwind speed without the dead-downwind hassle.
Reaches are where sailing feels effortless. If you're learning, spend your first sessions on a beam reach — it builds intuition for trim without the demands of pointing or jibing.
Running (dead downwind)
Wind directly behind, mainsail eased nearly perpendicular to the boat, headsail collapsed in the main's shadow (or poled out wing-on-wing). Slowest of the comfortable points of sail because boat speed subtracts directly from apparent wind.
The big risk on a run is the accidental jibe — wind catches the back of the main and slams the boom across the boat at speed. Rig a preventer line from the boom forward to a cleat any time you sail dead downwind in real breeze. Many cruisers prefer to tack downwind on broad reaches instead — slightly longer distance, much faster and safer.
True wind vs apparent wind
True wind is what a stationary observer feels. Apparent wind is what you feel on the moving boat — the vector sum of true wind and the wind your motion creates. Sailing upwind, apparent wind is stronger and farther forward than true. Sailing downwind, apparent is weaker and farther aft. Trim to the apparent wind (what the telltales see), but plan your course on the true wind.
Frequently asked
Beam reach to broad reach for most cruising boats — apparent wind is strong, sails are at full drive, the hull is at an efficient angle to the water. Racing boats with planing hulls or foils can be faster on a tight reach where they generate maximum apparent wind.
