A kit for modifying an in line skate to role in one direction only consists of locking plate having a rectangular central hole an a shoulder along one edge, a tubular sleeve having a rectangular head sized to non-rotatably fit within the central hole of the plate, and a wheel with a built in one way clutch with a central opening sized to receive the tubular sleeve. The apparatus further has a suspension element to which the displacement element is pivotally attached around an axis of rotation. Furthermore, by actively generating the control signals for the direct current switcher, explicit timing control circuitry is not required to synchronize the transmitted power to the sub-circuitry. The center stud is connected to the center element through a screwed connection. A top is used to contain the live lobsters under a cooling gel pack or layer of ice.
