Team Origin set out on their third AudiMedCup regatta in Barcelona with hopes of victory higher than ever despite the disruption and distractions that have plagued the British America's Cup contenders in recent weeks.

Two crew changes were unveiled following their domination of the practice race on Tuesday in which they fought off challenges from the ten other teams including 2009 champions Emirates Team New Zealand, who also top the 2010 leaderboard after two events.

The serious business gets underway on Wednesday with Team Origin skipper Ben Ainslie admitting to a new found confidence and direction among his team following some troubled times which led to the sacking of both former director Mike Sanderson and the Argentinian designer of their new TP52, Juan Koumoudjian.

Team Origin lies fifth overall after a mix of results at the first regatta in Cascais and then at Marseilles last month. While producing strong performances on the windward-leeward courses, they have struggled in the long coastal races in which their downwind speeds have proved disappointing.

Five days of racing starts on Wednesday with gentle 10 knot winds forecast each day. A coastal race may be left off the schedule if conditions favour the windward-leeward options.
