The Volvo Ocean Race power system

“Energy management on board a Volvo Ocean 65

will always be tricky due to the technical complexity

of the yachts and because the systems are used

in some of the most extreme conditions in the

world. During the 2014-15 edition, the Mastervolt

installation, including the CZone system, proved

to be very reliable and seamlessly handled every

situation with which the Volvo Ocean 65 was

confronted. In addition, Mastervolt is exactly what

I require from a race supplier. During the most

recent competition, Mastervolt was present at every

stop-over and provided excellent support. We see

Mastervolt as a full partner and look forward to

working together again.”




Based on its excellent service provision and proven

technologies, it is no surprise that Mastervolt

has again been selected as official supplier. Our

sustainable installations provide all systems with

electricity, from the canting keel to the watermaker

and media centre.

Previous races provided valuable technical

information: the alternators rotated some 88.2 million

times during the competition, while the advanced

Lithium Ion batteries were discharged 275 times.

Although the lifespan of these batteries is three times

as long as traditional batteries, their use is carefully

analysed. The engineers at the Mastervolt R&D Lab

in Amsterdam evaluate the performance of each

component to further refine the equipment and

ensure even greater reliability in their functioning in

extreme temperatures and humidity.

Following developments

The Volvo Ocean 65 One Design fleet offers more

space to the latest product developments from

Mastervolt and CZone


, specifically developed for

Digital Switching. Each installation must be identical

on every yacht: from the smallest screw to the cable

binders. This means that only the performance of

the crew will make any difference in the use and

control of the electrical system. In addition, the

Combination Output Interface (COI) from CZone

will replace the existing Output Interface module,

making the charging system smarter.

The Volvo Ocean Race is the toughest and most competitive of all fully crewed, professional

sailing events around the world. The 2017-18 edition promises to be even more intense with

the fleet racing over greater distances and making more stopovers.
