In an audio interview with Elaine Bunting this week, Dee Caffari talks about her bid to become the first woman to sail non-stop round the world against the prevailing winds and currents, the difficulties of negotiating the calms and squalls of the Doldrums and of managing sleep deprivation.

Elaine also talked to Dee’s weather expert Mike Broughton about the high-tech tools forecasters and weather routers are using, asks why they still get it wrong, and finds out from Dee’s coach what challenges she will be facing next week south of the Equator.
