Volvo Ocean Race

Our system in full detail

Naamloos document


The tailor-made power system that Mastervolt developed for the seven participating boats in the 2014-2015 Volvo Ocean Race is advanced to say the least. It is designed to run the normal range of electrical equipment onboard, as well as the very latest and most sophisticated communication equipment on the market. This helps organisers track and analyse the fleet's position and sailing conditions throughout the offshore legs from the race control headquarters in Alicante. Thanks to the latest video, satellite and multimedia content production technology employed by each team's On Board Reporter, the public will also be able to follow the boats over nearly 40,000 nautical miles of relentless ocean racing. And it will all be powered. Powered by Mastervolt.

The VOR/Mastervolt power system

The VOR installation in every boat is divided into two clear sections:

  1. A MasterBus that includes two Li-Ion Ultra Batteries, 24/150 A alternators, two MasterBus Alpha Pro regulators, one Magic DC/DC converter, one USB Interface, two 500 A latching relays, one DC 500 and one MasterShunt
  2. A CZone that includes one MasterBus/CZone Bridge, one 3.5’’ DI (digital interface), six output interfaces, two signal interfaces and one meter interface
Both sections are connected through a CZone/MasterBus bridge and collectively run the majority of the boats’ electrical requirements. The system enables monitoring and control of just about everything though the CZone 3.5” DI.

What the system needs to power and control

The circuits that are controlled by the Mastervolt VOR installation include:
  • Port and starboard water ballast pumps
  • Sat C (satcom messaging and positioning)
  • All lighting (both internal and external)
  • Fleet broadband 250 and 500
  • Cockpit and navigation MFDs
  • LAN network
  • B&G Multi-Functional Displays
  • Gas alarm
  • Radar
  • Bilge pumps
  • Two onboard PCs
  • VHF radio
  • AIS (Automatic Identification System)
  • Watermaker
  • Freshwater pumps
  • Electric-hydraulic keel pump and PLC controls As you can see, there isn’t much that’s not powered and controlled by Mastervolt on these Formula 1s of the ocean.


  • The seven participating boats are each powered by two Mastervolt Ultra 24/5000 Li-ion batteries, giving a total battery capacity of 360 Ah.
  • The batteries have a single primary source of charging via two 24/150 A Mastervolt alternators, regulated by two MasterBus Alpha Pros.
  • Each boat has a DC distribution 500 that provides fusing and monitoring for the two Alternators, CZone and the keel pump.
  • Battery monitoring is provided via the MasterShunt and the internal shunts fitted within the batteries. These components provide critical system data that is communicated via MasterBus and the CZone bridge onto the CZone DI (display interface), and the B&G Zeus displays located at the navigation station and in the cockpit.
  • There is comprehensive system monitoring provided via the CZone network, which will also emit audible and visual alarms when actions are required.
  • The CZone network also powers the navigation, communication and hydraulic systems fitted within the vessel.
  • When the boats are in port, charging is provided by a Mastervolt Charge Master 24/30-3.
  • Detailed system diagnosis and troubleshooting are provided remotely by the Mastervolt technical team, via Master Adjust, CZone Configuration Tool and Mastervolt QS.

One design

This edition of the Volvo Ocean Race is totally different from earlier years as it now features new one-design, 65- foot long, high-performance yachts, all equipped with the latest communication, safety and power technology – power technology by Mastervolt, to be precise. With our broad experience in the harsh marine environment, both leisure and commercial, we feel very much at home in this ultra-challenging environment.
