Posted on August 26, 2005

According to Ultra Dynamics, its twin UltraJet 376 waterjets were chosen by the Portuguese Navy for two new aluminium 16.1 m patrol boats built by Arsenal do Alfeite in Portugal for the Navy. Twin Scania DI12M diesel engines rated 460 kW at 2200 r/min are direct coupled to the waterjets providing propulsion for the vessels. During sea trials in Sesimbra Bay the vessels reached 27.5 knots at 2000 r/min at a displacement of just under 20 tonnes, comfortably exceeding the contract speed of 23.5 knots with a displacement of 19 tonnes.

Both vessels will be in service with the Direcção Geral de Autoridade Marítima – Polícia Marítima, their primary mission will be the undertaking of Search and Rescue and fishing surveillance along the Portuguese coastline.
