Marine Flap Rudder System Boat Propeller Shaft Rudder





The marine rudder is the main part of the steering system for vessels. The whole rudder system includes a rudder blade, rudder carrier, rudder pintle, rudder stock, etc. We can design different types of rudders as the requirement of our clients.

The Flap Rudder is the ultimate rudder solution when it comes to shipping maneuverability. With decades of research, development, and practical experience behind it, this rudder is the most mature design of all flap rudders in the shipbuilding industry. Optimized profiles, rudder balance, deflection ratio between rudder blade and flap, hinge, and link systems guarantee a reliable and efficient tool for your vessel.


Details for High-Performance Marine Ship Boat Flap Type Rudder



Flap Rudder I Type

Rudder angles of +/-45 degrees and additional 45 degrees of the flap permit extreme maneuvers and dynamic positioning operations. Each ship is different and for some rudder configurations rudder angles of 65°can be applied if a benefit for maneuvering is expected. Also attractive is the improved course keeping performance and fuel-saving obtained through smaller required rudder angles and smaller rudder area, compared to standard rudders.


The advantages of the flap rudders (I-type) are:


• Optimum balance and flap area

• Minimum steering gear size

• Highest insurance against flexural vibration

• High-efficiency ratio design

• Highest safety against cyclic stresses

• Durable in heavy-duty

• Easy maintenance of link and hinge system


Flap Rudder II Type

This type is an economical Rudder and especially suitable for small and low-speed vessels such as Riverboats, supply vessels, tug boats, fishing boats, or research vessels that can take advantage of this type of rudders for their special purposes.


The advantages of the Flap rudder (II-type) are:


• Better covering of propeller stream

• Reduction of the remaining forward thrust

• Easy installation

• Increase of side thrust

• Smaller rudder torque

• Smaller steering gear

• fewer stresses of steering gear
