Richard Mason explains how the damage occurred the the broken rudder stock. Team Sanya skippered by Mike Sanderson from New Zealand, arrive in Tauranga, New Zealand, after a broken rudder and hull damage forced them to sail back, during leg 5 of the Volvo Ocean Race 2011-12, from Auckland, New Zealand to Itajai, Brazil. They are now forced to retire from leg five and miss leg six of the race and ship their race boat and equipment to Miami. (Credit: Gareth Cooke/Volvo Ocean Race)
