Abstract: A remotely controlled submersible with a circular profile. A shaft crosses the submersible at the center on the pitch axis that is fixed to the external shell holding the thrusters. From this shaft the framework of the submersible hangs with all of the essential components and any additional weight required gaining the desired buoyancy. A motor such as a servo motor is mounted to the framework and is coupled to a gear, sprocket or pulley that is fixed on the center shaft. When activated the motor rotates the shell of the submersible along with the thrusters to the desired pitch while the internal frame remains low. The design of the submersible external body in relation with the internal body allows the submersible to pitch and maintain stability with a fixed center of buoyancy and center of gravity.

Abstract: A trim tab apparatus capable of causing the stern of a vessel to be raised or lowered relative to the surface of the water in which it rests. A trim tab plane can be pivotally attached to one or more arms that can be attached to a vessel by one or more brackets. When the trim tab plane is rotated in an aft direction as a vessel is moving, the force of water passing under the trim tab plane causes the vessel stern to be raised. If the trim tab planes are rotated in a fore direction as the vessel is moving, water is forced across the top of the trim tab planes causing stern-drag, so that the vessel stern is lowered in the water.
