Maneuvering Board

A maneuvering board is a navigational instrument used by mariners to plot the course and movement of a vessel. It is typically used in situations where precise navigation and maneuvering are required, such as during docking, anchoring, or avoiding collisions.

The maneuvering board consists of a flat surface with a grid pattern, usually marked with latitude and longitude lines. It also includes movable markers or tokens that represent the vessel and other objects in the vicinity. By using these markers and the grid lines, mariners can plot the current position of their vessel and track its movement over time.

The maneuvering board allows mariners to visualize the vessel's course and speed, as well as the positions and movements of other vessels or objects in the area. This information is crucial for making informed decisions and taking appropriate actions to ensure safe navigation.

In summary, a maneuvering board is a navigational instrument used to plot the course and movement of a vessel, aiding mariners in making precise navigation and maneuvering decisions. It falls under the supply class of Navigational Instruments in the supply group of Instruments And Laboratory Equipment.
