Clements Hyperform blades were chosen for Orca III.

Seawork exhibitor Clements Marine has supplied all the stern gear and propellers to one of the latest launches to emerge from Ireland based workboat builder Safehaven Marine.

Orca III, which was featured in the April issue of MJ, is the third Safehaven Wildcat 53/16m catamaran to be built. It is for a customer who is based on the Isles of Harris, in the Outer Hebrides, which provide some of the most challenging sea conditions to be found anywhere. Safehaven's Wildcat 53 has a high buoyancy bow and a twin chine symmetrical hull catamaran form which provides the exceptional levels of seakeeping to meet such challenges.

The vessel will have multiple operational uses, from long range offshore work going out in the North Atlantic to providing windfarm support, hydrographic survey, and long range passenger and dive support.

The vessel will regularly face waves of 6m and, as well as standing up to this test in terms of reliability and efficiency, the propellers also have to provide comfort for the passengers. For this purpose, Clements Hyperform blades were chosen. The unique blade profiles allow for optimum speed and acceleration, providing vibration free performance.

Clements Marine works closely with its customers to gain a good understanding of the proposed day to day use of the vessel so that the propellers and stern gear can be tailored to those specific requirements.

Having worked with Safehaven Marine for many years, Clements has built up knowledge of their boats and was very pleased when the sea trials were completed successfully with their equipment onboard.

Orca IIIis powered by Twin Scania D16 engines rated at 700hp and driving conventional stern gear, 762mm (30”) propellers on 88.9mm (3.5”) diameter shafts and large, balanced stainless steel rudders, through Twin Disc MG 5135 QuickShift gearboxes.
