Underway, or Under Way is a nautical term describing the state of a vessel. "Way" arises when there is sufficient water flow past the rudder of a vessel that it can be steered. A vessel is said to be underway if it meets the following criteria: * It is not aground * It is not at anchor * It is not drifting * It has not been made fast to a dock, the shore, or other stationary object. If a vessel is adrift and not being propelled by any instrument or device, it is said to be ''underway, not making way.'' The concept of whether a vessel is or is not underway has important legal ramifications. For example, in many jurisdictions a child must be wearing a personal flotation device at the time the vessel is underway. "Under weigh" is a variation, coming from folk etymology, first used in 1749. "Under way" is likely from the Dutch ''onderweg'' or Middle Dutch ''onderwegen'' (lit. "under" or "among the ways").〔Merriam-Webster Mobile Dictionary, 2015, entries for "under weigh" and "under way".〕 ==References== *"Maloney, Elbert S. ''Chapman Piloting And Seamanship. 65th Ed.
