Dee Caffari has turned the corner on her challenge to be the first woman to sail the wrong way round the world single handed. Now off Cape Town she will be heading back up the Atlantic blown by the trade winds towards her finish line at Brest. Her target is the 11th of May - 172 days at sea without no company but the birds and all the satellite gear that can be squeezed into a 72 foot Challenge boat.
And there's a challenge for armchair sailors and navigators - to predict where her return track will cross the outgoing one, with the prize £ 5,000 of travel vouchers.
