20 Rudder Commands Every Mariner Must Master Now

In the vast and often unpredictable world of the sea, a mariner's ability to control their vessel with precision and confidence is paramount. One of the most critical skills any sailor must master is the art of handling the rudder. This blog post delves into the 20 Rudder Commands that are fundamental for every mariner to ensure safe and efficient navigation. Whether you're navigating through narrow straits, executing maneuvers in harbor traffic, or facing challenging sea conditions, understanding these commands can greatly enhance your seamanship skills.

Understanding Rudder Dynamics

Before diving into the commands, let's briefly discuss what a rudder does:

• Purpose: The rudder is a flat, movable blade at the stern of a ship that is used to steer the vessel by directing its thrust.
• Function: When turned, it changes the direction of the water flow behind the ship, thus altering its course.

Key Principles:

• Effectiveness: The rudder's effectiveness depends on the speed of the ship; higher speeds make it more responsive.
• Response Time: Turning the rudder involves a delay from when the command is given until the ship actually changes course, due to momentum.

Essential Rudder Commands

1. Hard to Starboard

• Command: Turn the ship's helm hard to the right.
• Usage: Used in scenarios where a significant change of course to starboard (right) is required, often in emergency maneuvers.

2. Hard to Port

• Command: Turn the ship's helm hard to the left.
• Usage: Similar to hard to starboard but for a left turn, useful in avoiding obstacles or altering course swiftly.

3. Midships

• Command: Set the helm to the neutral or midships position.
• Usage: This command centers the rudder, stopping the ship from turning further, often used to prepare for subsequent commands or during docking.

4. Meet Her

• Command: Reduce the rate of turn or stop the turn of the ship by bringing the helm towards midships.
• Usage: Effective when fine adjustments to the course are needed or when an over-zealous rudder command has been given.

5. Steady as She Goes

• Command: Maintain the current course or rate of turn.
• Usage: This command instructs the helmsman to keep the ship on its current heading or on the rate of turn currently in progress.

6. Ease the Helm

• Command: Gently reduce the amount of rudder angle to lessen the turn.
• Usage: This helps in gradually reducing the rate of turn without stopping it abruptly.

7. Full Astern

• Command: Reverse the ship's engines to stop forward movement, often combined with helm commands for precision maneuvering.
• Usage: Critical in docking or in situations where a vessel needs to halt its progress quickly.

8. Check the Swing

• Command: Use opposite helm to counteract the ship’s momentum and reduce the rate of turn.
• Usage: This command is vital when the ship is turning too quickly and needs to be stabilized.

9. Keep Her So

• Command: Similar to "Steady as She Goes," with an emphasis on maintaining the current heading without any change.

10. Port 10 Degrees

• Command: Turn the helm 10 degrees to port.
• Usage: Used for minor course corrections, often in open waters.

11. Starboard 5 Degrees

• Command: Turn the helm 5 degrees to starboard.
• Usage: For fine-tuning the ship’s heading or in restricted waters where small adjustments are necessary.

12. Make Her Tell

• Command: Slowly and carefully bring the ship around using a gentle turn until it starts to respond visibly.
• Usage: Useful in confined spaces or when a delicate touch is needed.

13. Hove To

• Command: Stop all forward motion and maintain position against prevailing conditions like wind or current.
• Usage: This is not a rudder command per se but often involves rudder use to keep the ship in place.

14. Rudder Amidships

• Command: Same as "Midships," indicating the helm should be in the middle or neutral position.

15. Hard Over

• Command: Turn the helm fully in the direction last commanded.
• Usage: Critical in emergency scenarios where immediate maximum turning is required.

16. Ease to

• Command: Gradually ease the helm to a specific degree or direction.
• Usage: Allows for gradual adjustment to new headings or to alter the rate of turn.

17. Wheelsman, How’s Your Head?

• Command: A check on the current heading or condition of the vessel.
• Usage: Ensures the helmsman is aware of their responsibilities and the ship's current state.

18. Port Your Helm

• Command: Put the helm to port.
• Usage: To turn the ship to the left or port side.

19. Starboard Your Helm

• Command: Put the helm to starboard.
• Usage: To turn the ship to the right or starboard side.

20. Ease Her

• Command: A command to reduce the angle of the rudder without specifying a direction.
• Usage: For subtle course adjustments or when the speed of the turn needs to be moderated.

Practical Scenarios and Techniques

Maneuvering in Narrow Channels

• Starboard 5 degrees might be used to nudge the ship slightly to starboard when passing another vessel or avoiding an underwater obstruction.
• Steady as she goes would follow after the desired position is achieved.

Docking Maneuvers

• Full astern with rudder amidships to slow the ship's progress while maintaining control over its direction.
• Hard to port or starboard might be necessary for a quick, decisive turn into or away from a dock.

Emergency Situations

• Hard over or Hard to Port/Starboard are critical to avoid collisions or to respond to sudden changes in conditions.

Common Mistakes to Avoid:

• Oversteering: Overzealous rudder commands can cause the ship to oscillate excessively, leading to loss of control.
• Poor Communication: Vague or unclear commands lead to misinterpretations and can result in accidents.
• Ignoring the Ship's Momentum: Not accounting for the ship's momentum can result in a late reaction or overcompensation.

Final Thoughts

Mastering these rudder commands not only enhances your ability to navigate effectively but also instills confidence among your crew. As you've learned through this exploration, each command has its specific context and utility. Keeping these commands clear, concise, and well-understood can make the difference between a smooth voyage and a challenging one.

To further improve your skills, consider attending advanced navigation courses, practicing regularly with simulation software, and engaging in real-world scenarios with experienced mariners. The sea demands respect, and these skills are your tools to navigate its mysteries safely.
