A binnacle is provided for mounting a compass which compass consists of a compass card mounted on a jeweled bearing and within a compass liquid in a first container, which in turn is gimballed in two directions (orthogonally) into the binnacle housing. The binnacle housing for the gimbal rings and the entire gimbal pivot as well as the compass housing is immersed in a compartment filled with a second fluid to provide damping for the compass bowl and the gimbal assembly.
