Sir Robin Knox-Johnston has restarted the Five Oceans race in Fremantle three days behind the rest of the competitors after a broken autopilot.

The 67-year-old had to stay in port for a statutory 48 hours while his team resolved the wiring problem.
"We are pretty certain we have cured the problem that has bedevilled the pilots right from the start," he said.
"I shall be setting out with renewed confidence because the pilots will, at last, have the power they need."
Hampshire-based Knox-Johnston trails race leader Bernard Stamm by 776 miles but he is still confident of making up ground on the rest of the fleet including fourth-placed Unai Basuko.
"I am not worried about starting this far behind the others," he admitted.
"Bernard Stamm is off and away, Koji is in hot pursuit, Unai seems to be taking things easily and he is my first objective but there is some unpleasant weather ahead."
