By the end, you’ll know…
- Explain what makes a turn a tack.
- Connect tacking with progress towards an upwind destination.
- Recognise communication and lookout as part of the manoeuvre.
Imagine a destination lying in the direction the wind comes from. A sailing boat cannot simply point straight at it and keep sailing normally. It can make progress on suitable angled courses, changing between them. A tack is one way of changing which side receives the wind: the bow passes through the wind direction. Let us understand that picture on shore before attempting the movement aboard.
Follow the bow through the wind
The defining feature is the bow passing through the direction from which the wind arrives. The wind then comes from the other side. This distinguishes a tack from a gybe, where the stern passes through the downwind position. The words describe the boat’s relationship to the wind, not simply a left turn or right turn on a map.
Both directions of tack are possible. If you memorise only “turn left”, you will be stuck when the starting situation changes. A paper boat and a clearly marked wind direction make a better memory aid: follow the bow and describe its relationship to the breeze.
Why sailors zigzag upwind
The RYA’s points-of-sail guide describes making progress to windward using angled courses and tacks. Do not turn that introductory sketch into a promise of a fixed turning angle for every boat. The suitable courses depend on the boat and conditions.
Picture a picnic spot on the far side of a bay, directly upwind. The idea of angled legs explains how sailing there is possible; it does not choose a safe route through the real bay. Water depth, traffic, shorelines and local restrictions still matter. A lesson diagram is about one concept, not a complete passage plan.
The sail and crew have a changing scene
During a tack, the boat passes through a zone where the sails cannot drive it in the usual way. The sails can luff before filling on the new side. Meanwhile, the crew’s positions and tasks may change. The instructor demonstrates the actual sequence for your boat and the conditions; this page does not prescribe hand swaps, sheet timing or body movements.
It helps to watch a demonstration with one question in mind. On the first viewing, identify the bow’s path. On another, listen for the communication. Splitting the observations makes a busy manoeuvre easier to understand without asking you to copy every movement immediately.
Readiness must mean something
Before a planned turn, the crew needs a shared understanding of the instructor’s calls, assigned jobs and a clear way to report that someone is not ready. Learn the exact words used in your session. Answer honestly rather than echoing the person beside you; the point of a readiness check is to discover a problem while there is still time to address it.
Australian Sailing’s introductory video resources include tacking and explicitly complement a safety briefing and checks of understanding. Use a video to recognise the idea, then practise under instruction. Being able to explain the turn on paper is a useful start, not proof of practical competence.
Trace the bow
- Draw an arrow showing wind travelling from the top of a page towards the bottom.
- Place a paper boat on an angled upwind course and rotate its bow through the direction the wind comes from.
- Explain to a partner why this is a tack rather than just calling it a left or right turn.
Show Saily’s thinking
It is a tack because the bow passes through the wind direction and the boat changes which side receives the wind.
Three things to take aboard
- A tack takes the bow through the wind direction.
- Angled courses and tacks can make progress upwind.
- Readiness calls, lookout and boat-specific instruction belong to the manoeuvre.
Ready to test your sea sense?
Four questions. No timer. Try again whenever you like.
Still curious?
Does every tack turn through exactly the same angle?
No. The appropriate courses and resulting turn depend on the boat and conditions; a classroom angle is only an introductory illustration.
Is changing sides in the boat the definition of tacking?
No. The defining feature is the bow passing through the wind direction. Crew movement is part of the boat-specific practical technique.
Can I learn the complete manoeuvre from this page?
This page teaches the concept and questions to bring to a session. Learn and practise the actual manoeuvre with a suitable instructor.
