The new patrol boat is powered by two MAN B&W Diesel 12V 23/50 diesel engines, which were supplied by Alpha Diesel, Frederikshavn, Denmark, with 23V020 reduction gears, controllable-pitch propeller equipment and Alphatronic remote control. On sea trials, the speed of the Osprey 55 Class craft was 20.2 knots. The engines were installed in the vessel, which is a new version of the Osprey 50 Class patrol boat, at an inclination of 7 to 8 degrees to accommodate the 7-foot, four- bladed CP propeller. This was nec- essary because of the long flat but- tock run of the craft. The 12V 23/30 was developed by Alpha Diesel from its V23L engine and the compact in-line L23/30 en- gine. Cooperation between the de- sign engineers at Danyard and Al- pha Diesel led to an optimum usage of engine room space, while retain- ing easy access to the engines and gearboxes.
