Technical specifications
  Under sail the 3 blades are free to “weathervane” individually to the local water flow and not just feather in a fixed pattern aligned with the shaft. This patented feature really minimises drag and so further increases boat speed.

Our blades are of 40% glass reinforced hi-tech Zytel™, an extremely tough space age material, highly resistant to abrasion, chemicals and to repeated impact.

Hub castings are Stainless Steel 316, Nose cones in Delrin™. Pitch is easily adjusted externally and lubrication is also handled externally, so maintenance is simple.

The large area blades provide outstanding motoring capability, a real boon when punching through adverse conditions. There is instant full pitch in reverse and so stopping, berthing and reversing are simple, with minimal “prop walk” on most installations.
