Sailing upwind well is a balance of pointing and speed — steering and trimming to keep the boat both high towards the wind and fast through the water. It is the part of sailing that rewards the most practice, because small differences in trim and steering add up to big differences in how quickly you reach an upwind mark. Here is how to do it well. (For why a boat can sail upwind at all, see how a sailboat sails into the wind.)
Set up close-hauled
Sailing upwind means sailing close-hauled — as close to the wind as the boat efficiently can, around 45 degrees off it. The sails are trimmed in hard and flat: the mainsail near the centreline, the jib sheeted in tight. From there, the fine work is all in steering and trim, and it never stops.
Steer to the telltales
Your primary guide is the telltales on the headsail. Steer so the windward telltale is just on the edge of lifting — dancing, not fully streaming, not fully lifted. That is the boat at its best upwind. If it lifts, you are pointing too high; bear away a touch. If the leeward telltale stalls, head up. Good upwind helming is a constant, gentle conversation with those telltales.
Balance pointing and speed
The central tension upwind is pointing versus footing:
- Pointing — steering higher for more height, at the cost of speed.
- Footing — bearing away slightly for more speed, at the cost of height.
Pinch too high and the boat slows, stalls and slides sideways; foot too low and you sail extra distance. The fastest way to windward is a compromise between the two, adjusted for the conditions — you point higher in flat water and smooth breeze, and foot for speed in waves or light air.
Keep the boat flat
Heel is slow. When a boat leans too far, its keel and rudder grip less, it slips sideways, and the rudder drags fighting weather helm. So upwind you keep the boat as flat as you can — crew hiking out on the windward rail, and sails depowered in the gusts (easing the mainsheet or traveller, flattening the sails). A flat boat drives forward; a heeled one slides sideways.
Find the groove
Put it together and you are hunting for the groove — the narrow band of steering and trim where the boat is both high and fast, telltales streaming, sails drawing, boat balanced and light on the helm. A boat in the groove feels alive. Finding and holding it, shift by shift and wave by wave, is what upwind sailing is all about — and the trimming behind it is covered in how to trim sails. For the language, see the sailing terms glossary.
Frequently asked questions
- How do you sail upwind?
- To sail upwind you sail close-hauled — as close to the wind as the boat efficiently can, about 45 degrees off it — with the sails trimmed in hard and flat. You steer to the telltales, keeping the windward jib telltale on the edge of lifting, keep the boat as flat as possible, and tack back and forth to zig-zag towards the wind. The art is balancing height against speed.
- What is the difference between pointing and footing?
- Pointing means steering as close to the wind as possible to gain height, at the cost of some speed. Footing means bearing away slightly for more speed, at the cost of height. Good upwind sailing balances the two — pinch too high and the boat slows and stalls; foot too low and you sail extra distance. The best course is usually a compromise that maximises progress to windward.
- Why keep the boat flat upwind?
- Because excessive heel is slow. When a boat heels too far, the keel and rudder work less efficiently, the boat slips sideways more, and the rudder drags as it fights weather helm. Keeping the boat flatter — by hiking, easing sails or depowering in the gusts — keeps it driving forward rather than sliding sideways, which is why crews sit out on the windward rail upwind.
- What is the groove in sailing?
- The groove is the narrow band of steering and trim where the boat is sailing both as high and as fast as it can upwind — telltales streaming, sails drawing, boat balanced. A boat 'in the groove' feels light and fast. Finding and holding the groove, shift by shift and wave by wave, is the essence of good upwind helming.
- How do you sail upwind in waves?
- In waves you steer more actively — bearing away slightly to build speed and drive through or over a wave, then heading back up in the flatter patches to gain height. Trying to point too high into a steep sea just stops the boat. Keeping speed on so the boat has drive to get through the waves is the priority, then converting that speed back into height where you can.
