Concise answer
Tack by steering through the wind with crew weight shifting forward and across to keep the boat flat; gybe by turning the stern through the wind with controlled steering and a steady hand on the mainsheet to let the boom across under control. In both manoeuvres keep movements small, communicate clearly, trim sails progressively and look to keep boat speed through the wind to avoid stalling or sudden heel.
- Prepare: call the change, appointed helm and crew ready, check wind and traffic.
- Move weight early but smoothly: shift crew to the new windward side just before the boat comes through the wind (tack) or after the stern passes the wind (gybe) to keep the boat level.
- Helm control: steer a steady arc through the wind — not a sudden jam — to maintain speed. For gybes, avoid oversteering as that can accelerate the boom unexpectedly.
- Sail handling: ease the working jib/genoa slightly as you come through the wind, then trim it on the new side; for the mainsail, ease as needed and sheet in progressively once the boat is settled.
Why this matters
Losing speed through a tack or gybe makes you slow to accelerate on the new course and can leave you vulnerable in fleet racing or close quarters. Sudden or poorly-timed weight shifts and aggressive steering cause excessive heel, broaching or an uncontrolled boom swing — all unpleasant and inefficient.
Common mistakes (beginners)
- Waiting too long to move: causes excessive heel, increased rudder demand and speed loss.
- Over-steering: jerky or large rudder angles stall the boat and kill momentum.
- Letting the jib or mainsheet snap: causes a big loss of control and speed (and can be dangerous in a gybe).
- Poor communication: no clear calls or role assignment leads to awkward timing and wasted motion.
Practical next step
On your next outing, practice tacks and gybes in light-to-moderate conditions away from traffic: make a deliberate checklist before each manoeuvre (call, helm change, weight move, sail trim), do three tack/gybe cycles trying to keep boat speed steady, and compare how the boat feels when you move earlier versus later. Record what felt smooth and what stalled the boat so you can repeat the good habits.
Glossary: tack — turn the bow through the wind so the wind switches sides of the sails; gybe — turn the stern through the wind so the mainsail and boom cross to the other side.
