Marine coatings including cationic polymers hydrolyzable to nonfouling zwitterionic polymers, coated marine surfaces, and methods for making and using the marine coatings. There are provided a band-shaped tray 12 having grasping grooves 12a for grasping opposite side ends of wafers 1 and surrounding an outer periphery to expose upper and lower portions of the wafers 1, and a cleaning tank 20 to which the wafers 1 inserted in the tray 12 are conveyed by a conveyor robot 2 to be cleaned. Error checking circuitry performs a verification operation on a stored data value and an associated error code to determine if an error has occurred in at least one of the stored data value and the associated error code during storage.
