Vecta Marive UK suppliers of Kiwi props

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 50% 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 Glass filled Polypropeline. 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.
