The Saffir-Simpson Scale is a classification system that categorises hurricanes based on their wind speed and potential for damage. It ranges from Category 1 (weakest) to Category 5 (strongest), each representing a range of sustained wind speeds and associated impacts. The scale was developed in the early 1970s by engineer Herbert Saffir and meteorologist Robert...

Vertical post or support, typically made of metal, used on a vessel to hold lifelines, guardrails, or other safety barriers in place. Stanchions are an essential component of a vessel's safety infrastructure, providing support for lifelines or guardrails that prevent crew and passengers from accidentally falling overboard. These upright posts are usually constructed from durable...

A set of internationally agreed-upon phrases used to ensure clear, concise, and unambiguous communication at sea, particularly between vessels and shore stations. Standard Marine Communication Phrases (SMCP) were developed by the International Maritime Organization (IMO) to enhance safety at sea by reducing the risk of misunderstandings caused by language barriers. They provide a structured and...

A primary tidal reference location for which full tidal predictions, including times and heights of high and low water, are published.  Standard Ports serve as the main reference points for tidal predictions in nautical almanacs and tide tables. These ports have well-established tidal data based on long-term observations, allowing mariners to plan voyages, anchoring, and...

A warning, given by the helmsman, that he is about to gybe

The standing end refers to the part of a rope or line that is not actively being used or manipulated during a task or operation. It is typically the part of the rope that is secured or fixed in place. It is the opposite of the Working End.

The section of rope between the standing end and a knot being made.

The fixed lines, wires, or rods that support a sailboat's mast and keep it upright and stable. Standing rigging is a critical component of a sailboat's structure, providing the necessary support to ensure the mast remains securely in place under the various forces exerted by the wind and sails. Unlike running rigging, which is adjusted...

To maintain a safe distance from a specific location, object, or vessel, often to avoid collision or interference. A "stand off" in maritime terminology refers to the deliberate action or state of keeping a vessel at a safe distance from a particular point, such as a harbour, shoreline, or another vessel. This manoeuvre is often...

To maintain course and speed in accordance with the International Regulations for Preventing Collisions at Sea (COLREGs), when another vessel is required to give way. The term "stand on" is a concept in maritime navigation, particularly in relation to the International Regulations for Preventing Collisions at Sea (COLREGs). When two vessels are on a collision...
