What is Starboard Side? A Comprehensive Guide to the Right-Hand of the Vessel

In maritime language, the terms starboard and port are used to describe the two sides of a vessel relative to the direction the bow is facing. The starboard side is the right-hand side when you stand at the bow looking forward. This simple orientation is fundamental to safe navigation, mooring, and ship handling. In this guide, we explore what is starboard side, its origins, how it is used in modern shipping, and practical tips to remember the difference between starboard and port.

What is Starboard Side? A Clear Definition

What is starboard side? Put plainly, the starboard side is the right-hand side of a ship or boat when facing the forward direction of travel (the bow). When an officer or crew member instructs another to “keep her to starboard” or to steer “towards starboard,” they are directing movement toward the vessel’s right-hand flank. The opposite side is the port side, the left-hand side when facing forward. These terms are standard across most kinds of watercraft, from small ribs to ocean liners, and they help crews communicate quickly and unambiguously, especially in challenging conditions at sea.

What is Starboard Side? A Short History and Its Etymology

From Steorbord to Starboard

Delving into the history of the term helps explain why the right-hand side is called starboard. The word derives from old nautical language. In Old English, the side used for steering the ship was called steorbord, literally the “steering board.” The oar or rudder used for steering was located on the ship’s right-hand side in many early vessels, and thus the term evolved into starboard over time. This is a classic example of how practical shipboard practices shaped the vocabulary that sailors still use today.

The Shift from Larboard to Port

For the left-hand side, the term larboard once served as the standard. However, as ships grew more complex and the two directions needed to be communicated clearly in crowded or noisy situations, larboard began to collide with starboard in rapid speech. To avoid confusion—particularly during essential commands—seafarers settled on the term port for the left-hand side. Today, port remains the conventional term for the left side, while starboard denotes the right side. The pairing port and starboard is a worldwide standard in naval parlance, aviation jargon aside, remaining consistent across commercial fleets, fishing boats, and private craft alike.

Starboard and Port: How They Are Used in Modern Navigation

Navigation Lights and Signals

At night or in restricted visibility, ships rely on navigation lights to indicate their orientation. The starboard side is associated with a green light, while the port side bears a red light. This colour-coding allows other vessels to determine the relative direction of travel and assess potential collision risks quickly. A vessel approaching from the other direction will see red on your port side and green on your starboard side, helping to determine which vessel should give way in crossing situations. White stern lights indicate the rear of the vessel, while additional lights may signal a vessel’s size, activity, or status (e.g., underway, anchored, or not under command).

Rules of the Road at Sea

In addition to lights, the Rules of the Road (COLREGs) govern how vessels interact on the water. Knowledge of starboard is essential when determining right-of-way, especially in crossing or overtaking scenarios. For example, a vessel approaching from your starboard side has priority over you in many circumstances, and communicating clear intent with proper signals, whistles, and lights helps prevent collisions. Understanding what is starboard side and how it relates to the other vessel’s position is a practical skill that every mariner should master, from the seasoned captain to the casual day skipper.

Remembering Starboard Side: Tips and Mnemonics

Mnemonic Devices for Quick Recall

Many sailors rely on simple mnemonics to keep starboard and port straight. A common reminder is:

• “Right is starboard, green is seen.”
• “Starboard is the right-hand side when facing forward.”

Another handy tip is to associate starboard with the word “star” as a visual cue on charts or on deck markers. Some crews also link the word starboard with common items found on the right side of a ship (e.g., the ship’s bridge corridor, seawater intake, or emergency equipment) to create a mental map that reinforces memory under pressure.

Deck and Docking Cues

On many vessels, deck markings, rails, or signage near the right-hand side reinforce the concept of starboard. When docking or berthing, crew members may refer to the “starboard cleat” or the “starboard bow line” to indicate which side to approach from. Familiarity with these cues—paired with an understanding of what is starboard side—reduces confusion during manoeuvres, especially in tight harbour spaces or busy channels.

Starboard in Action: Real-World Scenarios

Recreational Boating and Yachting

For enthusiasts who enjoy sailing or leisure boating, understanding what is starboard side can enhance safety and enjoyment. When rigging sails, positioning a crew member on the starboard side can help balance the vessel and optimise performance. In docking scenarios, calling out “starboard” helps the helmsman align the boat with the quay, while guests and crew members know which side to expect assistance from. Even on a small motorboat, keeping track of starboard and port is essential for safe helming, safe anchoring, and smooth docking.

Commercial Shipping and Navy Vessels

On commercial ships and naval fleets, the discipline surrounding starboard and port is even more rigid. Watch officers use starboard to coordinate complex operations, such as manoeuvring alongside a berth, passing another vessel in a busy channel, or executing a formation change during a fleet exercise. For navy ships, the precise language of starboard and port is part of standard operating procedures, reducing miscommunication when orders must be executed with speed and accuracy.

What is Starboard Side? Practical Community Knowledge

Common Questions About the Right-Hand Side

Is starboard the same on all ships? In principle, yes. The starboard side refers to the right-hand side when facing forward on any buoyant vehicle or vessel. While the layout of equipment and the specific uses of the starboard side may vary between a dinghy and a destroyer, the orientation remains consistent. The port side, by contrast, is the left-hand side when facing forward and carries its own historical and practical significance.

What About Non-Nautical Contexts?

In most non-nautical contexts, the terms starboard and port are rarely used. Aviation, for example, uses different directional vocabularies, while the nautical terms persist primarily in ships, boats, yachts, and related maritime activities. When people refer to the right-hand side of a vessel in everyday conversation, they often use the words “right” and “left”; however, clear mariner’s language remains indispensable when the stakes are high at sea.

What is Starboard Side? A Concise Reference

To summarise, the starboard side is the right-hand flank of a vessel when looking toward the bow. The term’s origin lies in historical steering practices, with steorbord serving as a precursor to starboard. Modern practice pairs starboard with port, uses green navigation lights for the starboard side, and relies on COLREGs to govern safe passage and right-of-way. Whether you are a novice sailor or a seasoned captain, knowing what is starboard side and how it relates to the vessel’s direction is essential for safe and efficient seamanship.

Frequently Asked Questions About What is Starboard Side

Is Starboard the Same on All Ships?

Yes, the concept of starboard—the right-hand side when facing forward—is consistent across ships, boats, ferries, and yachts. The practical layout, of course, differs by vessel type, size, and purpose, but the orientation remains the same.

Can Starboard Be Affected by the Vessel’s Heading?

Starboard is defined relative to the bow, not to any other part of the vessel. If the ship changes heading, the right-hand side remains starboard. This consistent reference is critical for coordinating with other vessels and for following navigational instructions accurately.

Conclusion: The Starboard Side at a Glance

Understanding what is starboard side is more than a linguistic curiosity; it is a practical skill that supports safety, efficiency, and clear communication on the water. From its nautical roots in steering arrangements to its modern usage in navigation lights, signalling, and right-of-way rules, the starboard side represents a time-tested framework that keeps crews coordinated even under pressure. Whether you are learning to sail, piloting a commercial vessel, or simply curious about maritime vocabulary, grasping the distinction between starboard and port will serve you well on every voyage.
