Mari Cha IV, Robert Miller’s 140ft super maxi, has bettered her 24 hour distance record. Between 10:30 UTC on Sunday 5 October and 10:28 UTC on Monday 6 October, Miller and his crew sailed an incredible 511.4 nm (to be ratified by the World Speed Sailing Council). The previous day’s record ( see news story here ) was 505 nm.

Mari Cha IV is now over half way through her transatlantic record attempt and looks set to complete the voyage in well under eight days. The existing record is 8 days, 20 hours, 55 minutes and 35 seconds, set by Bernard Stamm onboard Armour – Lux.
