"Stand on Vessel" in a marine context refers to the ship or boat that, according to the navigational rules of the sea, has the right of way over another approaching vessel. This vessel is expected to maintain its course and speed, allowing the other vessel (also known as the 'give way' vessel) to take appropriate action and manoeuvre around it to avoid collision. It must standby, be observant and prepared to take action only if the 'give way' vessel does not. The 'stand on' status depends on several factors including respective headings, whether the vessels are power or sail, and whether they are in sight of one another.

1. An anchored ship in the harbor, in accordance with maritime protocol, has the right to stand on vessel while other ships are obliged to give right of way during navigation. 2. When two yachts or vessels are approaching each other in a crossing situation, the one which has the constant direction will be considered the stand-on vessel. 3. A fishing boat that is in operation makes it the stand on vessel, requiring other boats to navigate around it. 4. In foggy weather at sea, the vessel that hears a sound from forward of the beam has to hold its course and speed and is considered as the stand on vessel. 5. Sailing vessels have a special rule placed on them that gives them the role of a stand-on vessel when there are motorized vessels around. This allows them to safely continue their operations.

Fun Fact: The term "Stand on Vessel" comes from nautical terms, defining the rules of navigating waters to avoid collisions. Among these rules, is the concept of 'right'. Proclaimed by International Maritime Organization, the vessels who are given the 'right of way' are known as "Stand on Vessel". This means that in a situation where two boats are about to cross paths, the Stand on Vessel is the one that should maintain its course and speed, while the other vessel (known as the 'Give-way Vessel') should take action to avoid the collision. Interestingly, in navigating parlance, 'right' doesn't denote a direction, but a privilege. This maritime law ensures constant flow and safer navigation of waterways across the world.
