Marine navigation is the art and science of steering a ship from a starting point (sailing) to a destination, efficiently and responsibly. It is an art because of the skill that the navigator must have to avoid the dangers of navigation, and it is a science because it is based on physical , mathematical , oceanographic , cartographic ...
A running survey is a rough survey made by a vessel while coasting. Bearings to landmarks are taken at intervals as the vessel sails offshore, and are used to fix features on the coast and further inland. Intervening coastal detail is sketched in. [1]
Watercraft navigation lights must permit other vessels to determine the type and relative angle of a vessel, and thus decide if there is a danger of collision. In general, sailing vessels are required to carry a green light that shines from dead ahead to 2 points (22 + 1 ⁄ 2 °) abaft [note 1] the beam on the starboard side (the right side from the perspective of someone on board facing ...
A sector light is a man-made pilotage and position fixing aid that consists of strictly delineated horizontal angle light beams to guide water-borne traffic through a safe channel at night in reasonable visibility. Sector lights are most often used for safe passage through shallow or dangerous waters.
Mariners use position-fixing navigation, to obtain a "position fix" or "fix" by measuring the bearing of the navigator's current position from known points of reference. A visual fix of position can be made by using any sighting device with a bearing indicator to obtain position lines from the navigator's current position to each point of ...
Submarine navigation underwater requires special skills and technologies not needed by surface ships. The challenges of underwater navigation have become more important as submarines spend more time underwater, travelling greater distances and at higher speed.
Also ship's magazine. The ammunition storage area aboard a warship. magnetic bearing An absolute bearing using magnetic north. magnetic north The direction towards the North Magnetic Pole. Varies slowly over time. maiden voyage The first voyage of a ship in its intended role, i.e. excluding trial trips. Maierform bow A V-shaped bow introduced in the late 1920s which allowed a ship to maintain ...
A navigation system on an oil tanker. Navigation [1] is a field of study that focuses on the process of monitoring and controlling the movement of a craft or vehicle from one place to another. [2] The field of navigation includes four general categories: land navigation, [3] marine navigation, aeronautic navigation, and space navigation. [1]
