A system for securing a flexible cover to a boat is described. Driven gears of each transmission path are permanently driven during operation of the transmission. Controlled availability and generation of the keys required for encryption and decryption of data is such that even if back doors are accessed that previously encrypted data is impossible to decrypt and thus worthless even if a back door is found and maliciously pried open. If no match exists, a best-matching case is determined and selected. Methods of making same are also provided. The one or more detectors are in communication with an alarm.
