Design and manufacture of propulsion systems
We design and manufacture every type of propeller ensuring that we can supply exactly the right propeller whatever type of vessel it is for. We don’t have to try and sell a folding propeller when a feathering type will be better – we design and manufacture both, plus CPP’s and fixed. In addition to propellers our stern gear package includes shafting, thrust bearings, shaft seals and brackets. Our brands include Autoprop, Autoprop EcoStar, Varifold plus our anti-noise and vibration SigmaDrive.

Automatically operated hydraulic shaft lock to prevent propeller rotation when under sail or motoring with one engine
AUTOPROP
Automatic variable pitch propeller
Automatic variable pitch propeller
Autoprops provide drag reduction when sailing by at least 85% and a unique ability to change pitch automatically to suit prevailing wind and sea conditions when motoring or motor sailing. Auto pitching, auto feathering, the same thrust in astern as ahead, less prop-walk in astern, and a recently developed ability to produce very efficient and economic propulsion for purely diesel powered displacement motor boats make Autoprops a first choice for many vessel owners.
Autoprop Eco*star
New Autoprop for Hybrid drives and Motoryachts
New Autoprop for Hybrid drives and Motoryachts
Bringing with it all the benefits of the Autoprop propeller the version for electrically and hybrid powered craft, the Autoprop EcoStar, is the result of a considerable amount of research and redesign which ensures it is capable of providing highly efficient propulsion using the unique constant torque properties of an electric motor whatever the revs. The EcoStar matches its efficiency curve with that of the electric motor providing more boat speed whilst using much less energy.
Sigmadrive
SigmaDrive anti noise and vibration coupling
SigmaDrive anti noise and vibration coupling
The Bruntons SigmaDrive significantly reduces noise and vibrations because of its ability to eliminate up to 3 degrees of shaft misalignment in all directions. SigmaDrives are simple to fit on virtually all types of craft without changes to the vessels existing equipment. Once installed the seals and bearings are perfectly aligned, reducing wear and ensuring a trouble free life for all associated components.
Varifold
Two, three and blade folding propellers
Two, three and blade folding propellers
Bruntons Varifold propeller is available in 2, 3, and 4 blade versions and can propel yachts with engines from 10hp to 1000hp. It is the ideal propeller for cruiser racer and purely racing yachts and is now fitted as standard by some of the world’s top names in Superyachts. Designed to produce excellent thrust when motoring, with exceptionally low noise and vibration levels, when folded the Varifold reduces drag to a minimum.
