Safety:flap rudder blade is installed on boat,which will not cause hazard.
High efficiency:boats steering force of flap rudder blade is 1.5~1.8 times of that of the traditional rudder.
Economic efficiency:lower fuel oil consumption.
Environmental protection:flap rudder blade has double sealing ring to prevent oil from flowing into seawater to pollute the environment.
1.At the same steering angle of the main rudder, the flap rudder blade can provide greater normal force.
2.The rudder torque is small and the power of the steering gear is small.
3.We can tailor products according to the customer's drawings.
