Sailing against the wind, also known as "beating" or "tacking," can be challenging but it is an important skill for sailors to master.

Being able to sail against the wind means a sailor can sail their boat in most locations in the world.

To sail a sailboat against the wind:

  1. Check the wind direction
  2. Tack the boat
  3. Use the tiller/steering
  4. Adjust the sails continuously

Following these steps will allow a sailboat to sail windward.

1. Check The Wind Direction

The first step of sailing against the wind direction is the check the exact direction in which the wind is blowing.

To check the direction of the wind:

  • Use a wind indicator: Use a wind indicator like an anemometer to measure the exact wind direction
  • Check the onboard flag or sails: Look at the sails or flags onboard to get the exact wind direction
  • Check the weather forecast: Sailors can check the local weather forecast to get the exact direction the wind is blowing

Sailing against the wind requires a sailor to sail at an angle to the wind so a sailor will need to know the exact direction the wind is coming from to set this angle.

The benefits of checking the wind direction are it will inform the sailor of the exact wind direction so a tacking angle can be set and it will inform the sailor of the wind speed so they will know the force on the sails and keel.

2. Tack The Sailboat

The second step of sailing into the wind is to tack the sailboat, also known as "tacking".

Tacking is a sailing maneuver used to change the direction of a sailboat by turning the bow of the boat through the wind. This is also known as "coming about" or "beating."

When sailing, tacking is used to sail against the wind or to change the direction of the boat when sailing at an angle to the wind.

The tacking sailing maneuver means a sailboat will sail in a zig-zag direction against the wind rather than sailing at a 90-degree angle windward.
The zig-zag direction change means the wind will alternate between blowing on the starboard side and blowing on the port side.

For example, if the wind is blowing from the north, tacking would mean sailing the sailboat in the direction between northeast and northwest rather than directly north.

To tack a sailboat:

  • Alert the crew: Alert the crew that you're about to tack the sailboat to prepare them to go to a close haul. Close hauled is a sailing term used to describe the point of sail where the boat is sailing as close to the wind as possible. This means that the boat is heading upwind with the sails trimmed in tight and the wind coming from the side of the boat
  • Tighten the mainsheet: Tightening the mainsheet is used to adjust the angle of the mainsail in relation to the wind. The mainsheet is the rope that controls the mainsail and it runs from the sail to the aft end of the boat
  • Adjust the angle of the sails: Adjust the angle of the sails until the sailboat is sailing at a 45-degree angle against the wind. Sailing at a 45-degree angle to the wind direction will allow the sailboat to sail close-hauled and help it to travel in the direction of the wind without being stopped by the wind forces

The keel of the sailboat will provide stability and prevent the sailboat from capsizing or being blown sideways by the wind. The keel is a heavy, vertical fin-like structure that extends down into the water from the bottom of the sailboat's hull.

As the sailboat moves against the wind through the water at a 45-degree angle, the keel acts as a counterbalance to the force of the wind on the sails, helping to keep the boat upright and on course.

3. Use The Tiller/Steering

The third step of sailing against the wind is to continuously use the tiller/steering on the sailboat. When sailing against the wind, the tiller or steering is an essential tool that the sailor uses to maintain the boat's course and angle to the wind.

Using the tiller/steering system when sailing against the wind will:

  • Keep the boat close-hauled: When sailing against the wind, the boat needs to be pointed as close to the wind as possible. This is known as close-hauled sailing. To achieve this, the sailor must use the tiller or steering to keep the boat pointed upwind which helps the boat maintain its course and speed at a 45-degree angle to the wind direction
  • Balance the boat: When sailing against the wind, the boat is heeled over to one side as the force of the wind pushes against the sails. The sailor should use the tiller or steering to balance the boat and prevent it from tipping over. This involves making small adjustments to the boat's angle and direction to maintain a stable and controlled sailing posture. The keel will also help with the balance of the boat in the wind
  • Maintain forward momentum: Sailing against the wind requires a delicate balance between pointing the boat upwind and maintaining forward momentum. The sailor should use the tiller or steering to maintain the boat's speed and ensure that it is moving steadily forward even when sailing directly into the wind. Getting the right balance between sailing in a zig-zag pattern and maintaining boat speed is crucial

With practice and experience, sailors can become skilled at using the tiller/steering to navigate against the wind and enjoy the unique challenges and rewards of sailing upwind.

When steering the boat against the wind, a sailor should avoid:

  • Turning the boat too slowly: When steering the boat against the wind, avoid turning too slowly when tacking as this can cause the sailboat to get caught in irons which can halt any progress when sailing against the wind
  • Oversteering: When steering the boat against the wind, avoid steering it too much (oversteering) as this can result in the sailboat not pointing at a 45-degree angle against the wind and instead have the point of sail close reach or broad reach which will halt progress when sailing against the wind
  • Tangling the jib sheet: Jib sheets might tangle with some fixtures on the fore deck and will need to be unwrapped. To prevent this from happening, close all fore deck hatches, keep some tension on both jib sheets before and during the tack and clear off any item that may snag the sheets

4. Adjust The Sails Continuously

The fourth step of sailing against the wind is to continuously adjust the sails as the sailboat progresses upwind.

To adjust the sails when sailing against the wind:

  • Trim the sails: To sail efficiently upwind, the sails need to be trimmed in tight. This means pulling the mainsail in close to the centerline of the boat and tightening the jib sail to bring it as close to the wind as possible. This will help the boat maintain its course and speed and reduce the amount of sideways drift.
  • Watch the telltales: The telltales are small strips of ribbon or yarn that are attached to the sails and help the sailor gauge the airflow across the sail. When sailing against the wind, the telltales on the jib sail should be flowing straight back indicating that the sail is at the proper angle to the wind. If the telltales are fluttering or streaming forward, the sail may need to be adjusted
  • Use the boom vang: The boom vang is a line that runs from the bottom of the mast to the boom and helps control the shape of the mainsail. When sailing upwind, the boom vang can be tightened to flatten the mainsail and reduce its draft. This can help the boat sail more efficiently and maintain forward momentum
  • Adjust the traveler: The traveler is a device that runs across the cockpit or deck and allows the mainsail to be adjusted from side to side. When sailing upwind, the traveler can be moved windward to help keep the boat on course and maintain a balanced sail plan

Overall, adjusting the sails when sailing against the wind is a delicate balance between maximizing efficiency and maintaining control.

With practice and experience, sailors can learn to adjust the sails to suit the prevailing wind conditions and sail upwind with confidence and skill.

Frequently Asked Questions

Below are the most commonly asked questions about sailing against the wind.

How Long Does It Take To Learn How To Sail Against The Wind?

It will take a beginner sailor 3 to 5 attempts to properly sail a sailboat against the wind without any supervision. The timeframe of this is typically within 1 week of practicing 3 to 5 times. However, some sailors may take longer.

What Are The Forces When Sailing Against The Wind?

When sailing against the wind, there are four forces at play:

  1. Wind Force: The wind is the primary force that is opposing the motion of the sailboat. As the boat sails into the wind, the wind exerts a force on the sails that resists the forward motion of the boat
  2. Lift Force: The sails generate lift which is a force that propels the boat forward. When sailing against the wind, the lift force is reduced as the sails are not able to generate as much lift as when sailing with the wind
  3. Resistance Force: As the boat moves through the water, it creates a resistance force which is the force that opposes the forward motion of the boat. This force is influenced by the shape of the hull, the size of the boat, and the speed of the boat
  4. Friction Force: The friction between the water and the hull of the boat generates a force that opposes the forward motion of the boat. This force increases as the speed of the boat increases

When sailing against the wind, the opposing forces of wind and resistance become more dominant making it more difficult for the boat to move forward.

Sailors use the tacking technique which involves zigzagging back and forth across the wind to make progress against the wind. This allows the boat to use the lift force of the sails more effectively while minimizing the resistance force.

What Are The Benefits Of Sailing Against The Wind?

The benefits of sailing against the wind are:

  • Improved sailing skills: Sailing against the wind requires more skill and technique than sailing with the wind. It can be a great way to improve your sailing skills as you learn how to adjust the sails, steer the boat, and navigate more effectively
  • Access to more destinations: When sailing with the wind, a sailor's options for destinations may be limited by the wind direction. However, when sailing against the wind, a sailor can access more destinations that may have been previously out of reach
  • Greater control: Sailing against the wind requires more attention and focus but it gives a sailor greater control over the boat. A sailor can fine-tune the sails and the boat's position to optimize the speed and direction without issues or limitations
  • Challenge and adventure: Sailing against the wind can be a thrilling and adventurous experience. It requires mental and physical toughness and the satisfaction of successfully navigating against the wind can be very rewarding

Overall, while sailing against the wind may require more effort and skill, it can also provide a unique and exciting sailing experience with its own set of rewards.

What Are The Risks Of Sailing Against The Wind?

The risks of sailing against the wind are:

  • Increased risk of capsizing: When sailing against the wind, the boat may be more prone to capsizing due to the combination of wind and waves. The boat may be more difficult to control in these conditions and sailors will need to be prepared for any issues with the sailboat capsizing
  • Fatigue and physical strain: Sailing against the wind requires more physical effort and can be more tiring than sailing with the wind. This can lead to fatigue and physical strain which can affect a sailor's ability to navigate safely
  • Navigation challenges: Sailing against the wind may require more careful navigation and planning as sailor may need to navigate around obstacles and adjust their course more frequently. This can be challenging especially in unfamiliar waters or adverse weather conditions
  • Increased wear and tear on equipment: Sailing against the wind can be more taxing on the sailboat equipment as the sails and rigging are subject to greater stress, force, and strain. This can increase the risk of equipment failure or damage

To mitigate these risks, it is important to be prepared and to have the proper training and experience to handle sailing against the wind. This includes ensuring that the sailboat and equipment are in good condition, understanding the weather and navigation conditions, and taking appropriate safety precautions. It is also important to stay alert and attentive while sailing and to make adjustments as needed to ensure safe navigation.

What Should Be Avoided When Sailing Against The Wind?

When sailing against the wind, sailors should avoid:

  • Pinching: Pinching is a term used in sailing to describe the act of sailing too close to the wind. When sailing against the wind, the boat needs to sail at a 45-degree angle to the wind to maintain forward momentum and speed. Sailors should avoid pinching when sailing against the wind
  • Sailing in irons: Sailing in irons is when a sailboat is sailing directly against the wind. This will prevent the boat from moving forward against the wind and instead the sail angle will need to be adjusted to close haul to progress further
  • Turning too slowly or oversteering: When sailing upwind, avoid turning the sailboat too slow or oversteering it as this can affect the ability of the boat to travel against the wind effectively
