Misago Arrow, joins the Lawin Arrow and the Osprey Arrow Fleximax II Eco vessels, the latest in a long line of vessels to be delivered to Gearbulk from Oshima Shipbuilding Co. Ltd in Japan. She shares the same basic hull design, dimensions and service speed as our Fleximax II vessels also built at Oshima, with a similar deadweight of just under 63,000 mt.
However in the four years since the first of the Fleximax II vessels entered service, the cumulative effect of several design improvements will result in the Lawin Arrow and her three sister vessels consuming 13% less fuel at full speed.
These design improvements focus on three areas – the underwater paint system, the stern area and the main engine. The advanced anti-fouling paint which covers the underwater area prevents marine organisms attaching to the hull and has a low friction property which reduces the fuel needed to propel the vessel through the water. Two devices in front of the propeller – flipper fins and a pre-swirl stator, improve the flow of water into the propeller and hence its efficiency; and an improved rudder design reduces the energy losses in the water after it has passed through the propeller. The vessel is not fitted with a bow thruster and the elimination of the large thruster tunnel underwater reduces the turbulence of the water passing the vessel.
