HYDRAULIC, ELECTRONIC STEERING SYSTEMS

CHALLENGE FOR THE BEST SAILING Rudder Torque Calculation Hydraulic steering system should be selected by rudder torque. The formula for calculating the rudder torque is as follows. S x [0.4 x B – D] x V2 x 17.80) S: Rudder Area A: Rudder height (m) B: rudder width (m) D: Rudder correction width (m) V: Vessel Max Speed (Knot) ※Rudder Area = A x B(m ) 2 Rudder Dimension D B This condition is applied when the vessel's maximum speed is less than 25 knots. ※ Please contact our sales team for the vessel’s maximum speed more than 25 knots. ▶ The angle of from starboard to port was calculated as 80...
