Abstract: A small boat dynamic roll stabilizer. The stabilizer includes two or more pairs of spaced-apart flexible bellows or air bags to receive and support a boat hull during passenger loading and unloading. Dynamic pitch is limited or even stopped for the boat hull by maintaining each of the bellows, which each has a contact surface contacting a portion of the hull from below (within the water), at an internal pressure great enough to support dynamic loading of the boat hull while allowing the water to support the hull's static load. A pressure chamber is provided that has its interior volume linked via ducting or piping with the bellows, and a controller uses a feedback loop to operate an actuator to move a piston within the pressure chamber to maintain the pressure of the chamber and linked bellows as the loading of the boat hull dynamically varies during loading and unloading.

Abstract: A ride combining two or more vertical rotation axes with vertical translation motion of passenger vehicles. The ride includes a primary turntable rotating about a central axis and includes one to three or more secondary turntables mounted on the primary turntable to rotate with the primary turntable. Each of the secondary turntables is driven to rotate about a secondary rotation axis (vertical axis passing through the center of the sub-turntable). Each of the sub-turntables includes a vertical translation motion assembly that rotates with the sub-turntable and also supports a plurality of passenger vehicles. The passenger vehicles are supported within this assembly so as to be able to rotate (via manual operation or in a controlled manner) about a vertical rotation axis passing through the body of the vehicle. The vertical translation motion assembly is configured to allow each passenger vehicle to be lifted vertically upward a distance above the sub-turntable.
