In March I sailed out over 100 nautical miles off the coast to see how Solo UK rower Sarah Outen was going.
She was attempting to become the first woman to row across the Indian Ocean solo and unassisted from Fremantle to Mauritius.
She was caught in the Leeuwin current and swept down south of Bunbury. I found her over hundred nautical miles off the coast and it like trying to find a needle in a haystack, I eventually tracked her down using her automated tracker (which gives her longitude and latitude once every hour) - this got me close to Sarah and then I used Spirit's radar to pinpoint her position.
PS: Sarah is an inspiration, keep an eye on her travels too.
