Binnacle

(重定向自Bittacle)
Binnacle with iron correcting spheres at each side and clinometer below compass
A compass binnacle in front of the ship's wheel. The small stove-pipe chimney vents the lamp used to illuminate the compass face at night.

A binnacle is a waist-high case or stand on the deck of a ship, generally mounted in front of the helmsman, in which navigational instruments are placed for easy and quick reference as well as to protect the delicate instruments. Its traditional purpose was to hold the ship's magnetic compass, mounted in gimbals to keep it level while the ship pitched and rolled. A binnacle may be subdivided into sections and its contents typically include one or more compasses and an oil lamp or other light source. Other devices such as a sand timer for estimating speed may have been stored in the binnacle as well.
