Raidco Marine has delivered 4 of the first of a series of 11 Patrol Boats to the Gendarmerie Nationale.


Designed by naval architects Camarc, this new patrol boat has been sold by Raidco Marine, Lorient, and built by Ufast in Quimper, France, within weight targets and during trials has achieved speeds in excess of the required 33 knots. With new features for monitoring and intervention, this newly designed 11m patrol boat from Camarc is completely different from previous patrol boats delivered by Raidco Marine.  Using VSMP modeling (virtual symmetric multiprocessing architecture) these Camarc vessels are designed to provide coastal surveillance missions in the nautical band 5 and are unsinkable!  Thanks to its hard chine deep V-shaped hull the vessel combines high performance and exceptional sea keeping qualities for its patrolling roles and is capable of reaching high chase speeds.


The UFC 11.00 Alu is powered by twin Yanmar 6 LPA STP 315 hp engines @ 3800 rpm coupled to twin Ultra Dynamics’ UltraJet UJ305s waterjets via ZF63 reduction gearboxes; during sea trials the patrol boat reached a speed of 34 knots!  Reverse and steering is via an Ultra Dynamics hydro-mechanical control system. The patrol boat features a wheelhouse providing a maximum 360o field of view complete with a mini galley, work station, dinette and toilet, enabling 6 people to cruise comfortably.


Designed for the Gendarmerie Nationale, these boats will survey the French coasts against all kinds of risks – drugs, terrorism and immigration.  The following 7 patrol boats, fitted with UltraJets will be delivered by the end of June 2012.
