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! |
