Serial number location on Hobie Cat sailboats

Since 1973 the serial numbers on Hobie Catamaran sailboats has been located on the transom or rear of each hull. The number is hand-engraved using a vibration tool. The number is on both hulls of a catamaran. You can rub a small amount of graphite or soil into the serial number engraving to make it easier to read. Serial numbers use the following format: (example CCMB2345H989) Some older boats have had serial numbers engraved in a vertical direction parallel to the rudder pin.

Note: If an older boat has been painted, the serial number may have been covered over.
