The Mark I model has a displacement of 28 long tons (28 t), an overall length of 18.2 m (59 ft 9 in), and a maximum speed of 44 knots (81 km/h; 51 mph), and is armed with a M2 Browning machine gun. This particular model, and its predecessors, have been among the key types employed by the Hellenic Coast Guard.
