Average Reviews



Nakashima Propeller has succeeded in developing the world’s first CFRP propeller aimed at commercial vessels. Special characteristics such as ‘highly efficient’, ‘quiet’ and ‘lightweight’ allow for outstanding performance, obtained by making full use of material properties.


In 2015, Nakashima Propeller won the Prime Minister’s Prize at the 6th Monozukuri Nippon Grand Awards, with the title «developing the world’s first carbon fiber-reinforced plastic propeller for merchant ships in order to realize energy savings.


Special Characteristics


  • Weight is 1/5th of conventional NAP propellers, making installation easy.
  • Shaft diameter is reduced due to lower moment of inertia.


High Strength

  • Higher material fatigue resistance than conventional materials, increasing reliability.


Low Vibration

  • High damping performance drastically reduces vibration.
  • Improved living conditions


Overload Reduction

  • The shape of the blade is able to deform slightly to match water flow, reducing overload in case of rough conditions such as storms.


High Performance

  • Propeller efficiency is improved through a larger diameter.
  • Cavitation occurece is suppressed.


Improved Maintenance

  • If stocking spare blades, damaged blades can be replaced quickly.
  • Exchanging blades requires no special expertise, and blades can also be repaired


Reduced Torsional Vibration Stress

Because CFRP is both lighter and stronger than conventional NAB material, both propeller weight and moment of inertia are lower, reducing torsional vibration stress.


CFRP has a higher damping ration than conventional NAB material, leading to both suppressed singing and reduced torsional vibration stress.


Elastic Deformation

By deforming in the direction of pitch reduction due to increased load, during stormy weather (rapid load change) or acceleration, engine overload can be suppressed by letting energy escape through flow-induced elastic deformation.


Suppressing Cavitation

A CFRP propeller deforms according to load conditions, suppressing cavitation, leading to reduced stern vibration.
