Rudder solutions

The Amartech rudder systems are water lubricated and engineered for quick installation, dismounting and maintenance. Comfort and noise reduction are basic elements in the process of engineering at amartech.

The Amartech rudder systems could be divided into two sections, Custom Rudder Systems (CRS) and Modular Rudder Systems (MRS)

CRS (Custom Rudder Systems)

Starts with rudderstock Ø 80mm and larger

The Custom Rudder systems are specially engineered for the bigger Commercial Vessels, Yachts and Super Yachts and could be engineered according to any notation of Classification Societies like Lloyd’s, GL, BV, ABS, RINA and RRR.
The rudder blades will be custom engineered, fully adapted to the design of the vessel and could be supplied in steel, Stainless Steel and Aluminum. The rudder trunks could be supplied in Steel, Aluminum and Epoxy.

The system has the following features:

  • Free hinged
  • The rudder blade is custom designed based on NACA profile with most optimal shape for minimum resistance
  • Double secured rudderstock through lock nuts on the upper bearing and top side of rudder stock
  • The lever can be dismounted easily without demounting the rudder blade, maintenance of hydraulics becomes much easier
  • Steel and Aluminum rudder trunks are extruded and provided with welding flanges to prevent material tensions
  • The rudder trunk is provided with double seales at the upper and lower side to prevent for any leakage
  • The bearings are made out of contemporary high quality materials and provided grease nipples
  • Demountable bearing house for easy maintenance
  • Rudder blades provided with hoisting eye


MRS (Modular Rudder Systems)

Starts from rudderstock Ø 40 up to 70mm

The Modular Rudder systems are engineered and produced for motor yachts, sailing yachts and commercial vessels and could be supplied with short delivery time as most parts are available from stock. These systems are provided with our unique Easystern® clamp seal system.
The rudder blades could be supplied in steel, Stainless Steel and Aluminum and the rudder trunks could be supplied in Steel, Aluminum and Epoxy.

The system has the following features: 

  • Free hinged or with foot bearing
  • Rudder blades are available in different shaped like balance rudder, fishtail rudder and unsupported spade rudder
  • The rudder blade could also be custom engineered, fully adapted to the design of the vessel
  • The rudderstock is double secured through lock nuts on the upper bearing and top side
  • The lever can be dismounted easily without demounting the rudder blade, maintenance of hydraulics becomes much easier
  • Steel and Aluminum rudder trunks are extruded and provided with welding flanges to prevent material tensions
  • The rudder trunk is double sealed at the lower side to prevent for any leakage
  • The bearings are made out of contemporary high quality materials
