Co-skippers Blake and Knox-Johnston described the day as 'the most fabulous but hair-raising sailing any of us has done'.
Into the 25th day, there is good reason to hope for even better performances. Enza has averaged 14.41 knots for the 8,300 miles so far.
Meanwhile, Alain Gautier, in the 60-foot monohull Bagages Superior, has extended his lead in the Vendee Globe single-handed non-stop round the world race to 894 miles over Philippe Poupon, in Fleury Michon.
