The ship control device is provided with processing circuitry. The processing circuitry receives operation inputs from an actuator that controls the propulsion state of the ship, including the propulsion force and moving direction. The processing circuitry controls the navigation of the ship in a plurality of navigation modes, including a manual navigation mode using the operation inputs and an automatic navigation mode that maintains the propulsion state. When the processing circuitry receives a direction change operation input to change the moving direction in the operation input in the automatic navigation mode, the propulsion force of the ship is changed from the maintained propulsion force.

A sonar transducer assembly including a housing and a plurality of transducer elements is disclosed. The housing has a cylindrical shape. The plurality of transducer elements is arranged in the housing. The plurality of transducer elements is arranged in a longitudinal direction of the housing so that, at any position of the longitudinal direction, a number of the transducer elements is no more than one. Each of the plurality of transducer elements extends in a radial direction of the housing and includes a transceiving face facing outward of the radial direction. Extension directions of adjacent transducer elements of the plurality of transducer elements are different from each other.
