Varifold Folding Sailboat Propellers

A Better Folding Sailboat Propeller

Varifold folding propellers have taken the market by storm. Regularly fitted by such notable yacht building names as Baltic, Swan, Leopard Catamarans, Moody and Oyster. The complete range of Varifold folding sailboat propellers has a model for cruiser racing and racing yachts of every size for 2 blade folding propellers a 3 blade folding propeller and a 4 blade folding propellerVarifold 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.

Why do they look different?

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.

Varifold 4 blade background

So advanced is Varifold folding sailboat propeller design that a 4 blade version has successfully been fitted to a yacht with a 750 HP 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!

Why Choose Varifold Folding Propellers?

There are many choices when choosing a sailboat propeller. There are three main types to choose from: fixed, folding and feathering. The fixed propeller provides the best propulsive solution but has significant drag when locked-off under sail. The drag can be as much as a knot of lost speed. The feathering propeller is great to use in an aperture and has low drag when not in use, but the flat paddle like blades are significantly less efficient than a fixed pitch propeller and prone to noise and vibration when in use. The folding propeller offers all of the advantages of a fixed pitch propeller with none of the drawbacks. Check out our page on the design of folding sailboat propellers to learn more!

Varifold propeller benefits

A good fit for my boat?

The Varifold model range is extensive. There is a propeller available to fit most yachts with engines rated up to 1000 HP. Versions specifically designed for saildrives are also available. Fore the larger sailboats over 100 ft in length Varifold folding sailboat propellers dominate the market as few manufacturers are able to design and manufacture a folding propeller able to deliver the required thrust efficiently, quietly and without vibration while remaining structurally sound. Details of the Varifold sailboat folding propeller are below and further information can be found in our brochure.

Varifold propeller parts

The Varifold folding propeller is relatively simple to install and simple to service.  As with all the propellers they will be prone to galvanic corrosion and care must be taken to ensure that they are protected using what is known as sacrificial anodes or ”zincs” by many people.  The general idea is that the corrosion caused by stray current will be directed to the ”sacrificial” zinc rather than the expensive propeller.  Depending on the propeller this may require anodes on the propeller, on the propeller shaft or both.  Our years of experience and production methods ensure we can keep your Varifold propeller working at its best for many, many seasons.
