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 fitted 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 fitted 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.

So advanced is Varifolds design that a 4 blade version has successfully been fitted to a yacht with a 750hp engine, we believe that would have been an impossible task for any other folding propeller. Each Varifold, whatever its size, is built to the same extremely high specification from a nickel-aluminium-bronze alloy which guarantees great strength and high corrosion protection. Cruiser racing and racing yachts can now get the best of both worlds; a folding propeller that combines low drag when sailing, with efficient and quiet power when motoring. Oh, and by the way – Varifolds open in reverse, and not just sometimes!

From 10hp to 1000hp there is a Varifold propeller for your yacht, whether it is a small cruiser racer that does more cruising than racing, or an out an out racer that just needs a propeller to get back into port.

Our two, three and four blade versions are designed to produce excellent thrust when motoring with exceptionally low noise and vibration levels, and when folded for sailing, to reduce drag to a minimum.


Many well-known yacht manufacturer’s now fit Varifold as standard and the list of yachts re-propped with a Varifold to solve existing problems grows longer.



Even to the untutored eye close examination of a Varifold says excellent design and build quality. Hardly surprising when you realise that Bruntons Propellers are far from just being a supplier of propellers to builders and owners of leisure craft. The company designs and supplies propellers of the most advanced design to navies and commercial shipbuilders around the world and our in house designers, engineers and Naval Architects who work on those projects also bring their undoubted expertise to Varifold and our other leisure propellers.

Design of course is only one part of the process; a brilliant design is nothing unless matched by the highest quality build materials and construction processes. Our state of the art CNC manufacturing plant allows us to ensure that Varifolds highly advanced design features, like the special low pitch at the blade tips, which contributes so much to the excellent low noise and vibration characteristics of the propeller, can actually be manufactured and accurately reproduced on every blade.

Everybody involved strongly indicates that your propeller more than lives up to the expectation we had for it. Vibration and noise reduced dramatically plus the power and speed going forward increased substantially.

We launched that new 94 with the Yanmar engine, we all knew that we were a bit on the edge with this engine for a 94 footer, but the result is not bad at all, even slightly better than our expectation.

In conclusion, I would say that we are quite happy with the result.

I am very fond of your 4 blade Varifold propellers which I normally recommend.

Noise due to cavitation is much reduced and there is generally less vibration throughout the boat while motoring.

I’d say that top end motoring speed is about half a knot greater than before, as predicted by Bruntons.
