The Two Ways to Change Direction
Every time you need to change the side the wind is coming from, you perform one of two maneuvers: a tack or a jibe. Both accomplish the same end goal — getting the wind on the opposite side of the boat — but they do it in opposite ways, and the risks involved are very different.
Tacking: Turning Through the Wind
When you tack, your bow passes through the eye of the wind. You go from close-hauled on one tack to close-hauled on the other, momentarily passing through the no-go zone.
Step-by-Step: How to Tack
- Check for traffic and obstacles. Make sure your new tack is clear — look for other boats, mooring buoys, and shallow water.
- Build speed. A slow boat in a tack will get stuck in irons. Come in with good momentum.
- Call "Ready about!" Alert the crew. They respond "Ready!" when prepared to handle sheets.
- Call "Helm's alee!" and push the tiller away (or turn the wheel toward the wind). The bow begins to turn through the wind.
- Release the old jib sheet as the jib starts to backwind (or just after).
- Trim the new jib sheet as the bow comes through and the jib fills on the new tack.
- Ease the mainsheet slightly if needed, then trim to the new course.
- Adjust course to your desired heading on the new tack.
Common Tacking Mistakes
- Tacking too slowly: The boat loses steerage and gets stuck head-to-wind.
- Over-steering: Turning past close-hauled on the new tack wastes distance to windward.
- Releasing the jib too early: The backed jib actually helps push the bow through — hold it a beat longer.
Jibing: Turning Away from the Wind
In a jibe, your stern passes through the wind — you're turning downwind. The mainsail swings across the boat, and on a windy day, it does so with serious force. A controlled jibe is a normal, elegant maneuver. An accidental jibe — where the boom crashes across uncontrolled — can injure crew and damage rigging.
Step-by-Step: How to Jibe
- Check conditions and clear the cockpit. Make sure everyone knows the boom is about to come across and to duck.
- Call "Ready to jibe!" Crew responds when prepared.
- Begin to bear away (turn downwind) gradually. Don't rush.
- Trim in the mainsail as you head toward a dead run. Pulling the main to the centerline controls the force of the jibe.
- Call "Jibe ho!" and continue to bear away until the wind crosses the stern.
- The boom swings across. With the main pre-trimmed, this happens in a controlled arc rather than a violent crash.
- Ease the mainsheet on the new tack as the boom settles on the new side.
- Trim the jib to the new tack and adjust course.
The Preventer: Your Best Friend on Downwind Runs
A preventer is a line rigged from the end of the boom to a forward cleat or block, preventing the boom from accidentally jibing in confused seas or during an unexpected wind shift. If you're on a long downwind passage, always rig a preventer. It gives you time to react and protects crew from an unexpected gybe.
Tack vs. Jibe: When to Use Each
| Situation | Recommended Maneuver |
|---|---|
| Sailing upwind, changing tacks | Tack |
| Sailing downwind, changing tacks | Jibe |
| Light winds, comfortable conditions | Either works well |
| Heavy weather downwind | Consider a "chicken jibe" (tack instead) |
| Running in confused seas | Use preventer, minimize jibes |
Practice Makes Smooth
The best way to become confident in both maneuvers is repetition in controlled conditions. Pick a calm day, find a quiet stretch of water, and practice 20 tacks and 20 jibes in a row. Focus on timing, communication, and smooth sail handling. By the end of your session, both maneuvers should feel natural — and your crew will thank you for it.
