The Extreme Sailing Series™ has passed the halfway stage of the 2013 annual global Stadium Racing tour and having delivered racing in the Middle East, Asia and Europe, the eight formidable Extreme 40s are back for the second consecutive year in Cardiff, Wales for the only UK stopover.

But the Swiss and Omani teams have to watch their backs, with SAP Extreme Sailing Team and Red Bull Sailing Team waiting in the wings to pounce.
