A year of events celebrating our Sesquicentennial Anniversary will kick off at the All-New London Boat Show on the 10th January to celebrate our 150th birthday. 

Whatever type of vessel you require a propeller for you can be sure that Bruntons have the solution – not just any solution but exactly the right one. Why? Because Bruntons are the one company in the world that designs and manufactures just about every type of propeller in regular use today. We have no reason to try and get you to settle for second best because we will have the perfect answer.

In the world of leisure yachting our leading brands; the Autoprop feathering propeller and the Varifold folding propeller are acknowledged as world leaders in sailing boat propulsion. Our fixed bladed propellers for motor yachts, commercial and naval craft, are designed and manufactured to the same exacting standards in order to provide outstanding performance.

In this website, from the product links, you will find answers to many of your questions but if you don’t, please contact us and we will be very happy to help. Our one aim in life; to provide you with perfect propulsion for your vessel whatever it might be.

The Autoprop feathering propeller for cruising sailing yachts, displacement motor vessels, hybrid and purely electrically driven craft with engines to 350hp

Autoprop’s unique design and superb build quality make it the first choice feathering propeller among cruising yachtsmen the world over, with 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.


Varifold – the folding propeller for larger cruising yachts, cruiser racers and purely racing yachts of all sizes with engines from 10 to 1000hp.

Varifold folding propellers have taken the market by storm. Regularly ftted by such notable yacht building names as Baltic, Swan, Wally, Moody and Oyster, the complete range of Varifolds has a model for cruiser racing and racing yachts of every size. Varifold is revolutionary in design and brings a revolution to the yachts they are ftted to. Radical reductions in noise and vibration and excellent performance under engine, both ahead and astern, are the result of the propellers unique design. Varifolds have proper helical pitch distribution, including pitch reduction towards the blade tip. This pitch reduction ‘unloads’ the blade tips and, combined with the skewed blades, greatly reduces noisy pressure pulses against a yachts hull. While some other folding propellers have a helical pitch shape, few have proper sections or pitch distribution. None, put all these requirements into a complete package, except Varifold.

An excessive amount of engine power is always available, because this propeller comes up with the optimum efficiency at any speed.

Yacht Magazine

The qualities of the Autoprop make it perfect for long distance cruising.

Voile Magazine

Certainly one of the most interesting propellers in our survey. It demonstrated good speeds under all conditions.

Vela Motore

Our tests show the Autoprop achieved 6 knots at 2500 rpm compared to 2500 rpm for our standard prop and most of the others on test.

Yachting Monthly

At RPM’s up to 2000, no other propeller can beat the Autoprop, it clearly gave more speed.

At Bruntons we are very well known for the exceptionally high quality of the propellers that we produce, whatever the type of vessel they are intended for. Using many years of experience, and manufacturing processes that exceed the most exacting international standards and classification society requirements our designers, metallurgists and naval architects produce propellers, with or without complete sterngear packages, which are second to none.

Each propeller we produce is designed to ensure that it performs at maximum efficiency, providing the vessel to which it is fitted with the best performance, not just in speed but also fuel consumption and emissions; all this performance to be provided with the lowest possible noise and vibration.


Bruntons Propellers, throughout its history has never been a ‘me too’ company. Every product designed and manufactured by us is the result of extensive research, development and testing with the resulting equipment being either a substantial improvement on currently available products, or completely unique in its field.

Whilst our new CPP system is entering a market which already has many other companies producing CPP propellers the new Bruntons system has so many revised and unique features it could almost be described as unique itself.


Bruntons SigmaDrive is a brand new 21st Century solution that is already an award winner and provides effective anti-noise and anti-vibration solutions of the highest order.

What makes SigmaDrives different is their ability to resist propeller thrust when installed as a standalone coupling, directly from the shaft to the output flange on the engine’s transmission. It reduces and even eliminates vibrations that originate from an imperfect alignment between the propeller shaft and the engine, compensating for up to 3 degrees in all directions. This system can also be installed using thrust bearings so that the engine can be placed utilising the space available ergonomically.


The latest news from the world of Bruntons…


Bruntons have been in existence for over a hundred years. Today the business is a part of the Stone Marine Group; a group of companies specialising in all aspects of vessel propulsion. At Bruntons we have expert knowledge on the propulsion of leisure yachts, sail or power, and small to medium size commercial and naval vessels. Our knowledge extends across all aspects of the design and performance of propellers and their associated sterngear and our metallurgists will ensure that the propeller you order is produced using the right combination of metals for the environment in which the propeller will be working.

Today, most propeller companies will ‘go on’ at length about the equipment they use to manufacture the propellers they sell and the design programs that they use to design them. You can rest assured that at Bruntons we ensure that both our designing and manufacturing processes are state of the art. However the major difference you will find using us is the breadth of our experience. There is very little that we have not already done and learnt from!
