Comprising three vessels, the class was constructed in South Africa and entered service in 1992.

These boats are twin-hulled catamarans of glass-reinforced plastic (GRP) sandwich construction, with a complement of 16 personnel including one officer.

The boats are propelled by two Hamilton water-jets powered by two ADE 444 Tl 12V diesel engines creating 2,000 horsepower (1,500 kW).

Each vessel possesses a Racal-Decca I-band surface search radar unit and a single 12.7 mm (0.50 in) heavy Browning machine gun.
