Altitude
Altitude in maritime context refers to the height of an object or point in relation to sea level. It is an important measurement used in navigation to determine the position of a vessel. Altitude can be measured using various instruments such as a sextant or GPS. In celestial navigation, altitude is used to determine the angle between the horizon and a celestial body, such as the sun or a star, which can then be used to calculate the vessel's position. Altitude can also refer to the height of a vessel above the waterline, which is important for determining the vessel's stability and safety.
