A storage device for accessories, such as wakeboards and the like on a boat, may be mounted to maximize space and secure objects for storage. A tolerance between the second bearing and the rotation shaft and a tolerance between the first bearing and the rotation shaft are different, so as to cause hydrodynamic lubrication to occur at one of the first or second bearings. The chromic material is bistable so that the chromic material remains in the second color state for a significant amount of time. The user interface allows creation of shift alteration templates and associating templates with workers. Typically, a catalyst supporting layer is applied over the anti-corrosive layer. The system comprises a light source for generating a light beam, a light detector for detecting the light beam, and at least one reflector all mounted inside the enclosure.
