Sunreef Yachts introduced a new IPS system to its power catamaran range.
Despite the joystick’s popularity on motoryachts, it is uncommon on catamarans, especially the large models that Sunreef specializes in.
The shipyard decided not to build a completely new hull dedicated to IPS propulsion, but to modify the hull of the 60 Sunreef Power model. There were several challenges associated with arranging placement for IPS units in the engine rooms and the correct positioning of IPS units in relation to water level and hull position, the company said in a statement. This task is rather simple for wide monohulls, but requires much more planning on narrower catamaran aft sections. Sunreef said the research resulted in success and the positive results have even surpassed the owner and engineers’ expectations.
The engineering department is working on a new motoryacht, the 90 Sunreef Power, and doing hull optimization calculations to enhance the performance, motion at sea and savings on fuel. The hull had originally been forecast with a standard shaft line. The company is working on the IPS version of this boat so two propulsion systems can be available on the same hull shape, according to demand.
