Dec 13 (Reuters) - Brazil's Lucas "Chumbo" Chianca survived two brutal wipeouts to claim another Nazare Big Wave Challenge title in huge, clean waves in Portugal on Saturday, while France's Justine Dupont sealed her reputation as the world's best female big wave surfer with her second straight win.
The unique event saw nine teams of two taking turns using jet skis to tow each other into waves of up to 60 feet in front of thousands of fans lining the cliffs at Praia do Norte near the Portuguese fishing town that has become synonymous withenormous surf. The best team performance was won by Portugal's Nic von Rupp and France's Clement Roseyro.
