Abstract: An inflatable deployable mast fairing assembly is provided with a rigid foundation, a hydrodynamic fairing and at least one soft actuator. The hydrodynamic fairing is shaped to close an aperture formed between a deployable hardware system and a sail bay opening. A first soft actuator connects to the rigid foundation at one end and to the hydrodynamic fairing at another. Fluid pressurization elongates a first soft actuator coaxial to the deployable hardware system to fittedly position the fairing in the aperture with a void in the fairing to receive the hardware system. If the rigid foundation is sail-mounted, a second soft actuator connects to the sail-mounted foundation opposite the first soft actuator and to a counter flange mechanically connected to the hydrodynamic fairing. A second pressurization elongates the second soft actuator coaxial to the deployable hardware system to retract the hydrodynamic fairing from the aperture.

Abstract: A ship steering device includes a handle which is mechanically separated from a rudder mechanism, a steering angle detecting unit that detects a steering angle of the handle, a reaction force motor that generates reaction force torque to be applied to the handle, and a reaction force controller that controls, based on a steering characteristics map, the reaction force motor in such a way that the reaction force torque in accordance with the steering angle is obtained. The steering characteristics map has characteristics in such a way that the amount of change in an aiming steering torque relative to the steering angle is smaller in a second steering range where the steering angle is larger than that in a first steering range than the first steering region where the steering angle is set in advance from zero.
