Triple Rudders

Name: Triple Rudders
Brand: Nautican

Three-blade rudder system with differential linkage that deflects nozzle outflow up to 60 degrees, for vessels that tow, push and berth ships.

Description

Nautican Triple Rudders improve the maneuverability of vessels with nozzles. They use a differential linkage, a unique geometry, high aspect ratio foils and the cascade effect to create higher lift with less drag.

Key features

Deflects the entire propeller outflow up to 60 degrees to the side without loss of thrust or engine loading
In trials, rudder side force measured 74 percent of bollard pull, a 34 percent increase over a flap (Becker) rudder system
Low torque requirement, single steering gear and compact footprint, allowing the propeller to be located further aft
Delivered with all three blades and pintle bearings assembled and aligned
On twin-screw vessels with two steering gears, lets the vessel walk sideways
Available as part of the IPU or separately
