Volvo Penta folding propeller offers up to 1.5 knots higher

speed under sail compared with a ﬁxed propeller. With no

complicated machinery or mechanisms to cause trouble, the

propellers provide superb reliability. The folding propellers are

manufactured from a nickel-aluminium-bronze alloy which

ensures excellent corrosion resistance.

2-BLADE FOLDING PROPELLER

Available for both sail drive and shaft. Propeller size has to be

calculated to match engine and gear ratio. Use calculation program

or propeller diagrams. For a complete propeller, order one blade kit

and one hub kit.

The folding propeller’s greatest advantage is itslow drag under sail. The

folding propellers offer outstanding manoeuvrability. Despite being a

folding propeller, reverse thrust is fully comparable with that of a ﬁxed

propeller. The 3- and 4-blade propellers offer more or less the same

speed as a 3-blade ﬁxed propeller across the full rev range. Upto 8

times lower drag compared to a 3-blade ﬁxed propeller. And, what’s

more, the unique blade proﬁle promotes an extremely quiet and

vibration free operation.

Water drag were measured in a test

carried out by SSPA Maritime Consulting.

Propellers mounted on S-drives were

measured. The lower drag produced by

the Volvo Penta folding propellers can

boost sailing speed by up to 1.5 knots.
