Mari-Cha IV

Mari-Cha IV is a schooner superyacht, built for American billionaire Robert Miller with the goal of winning sailing records.

During the run she also won the record for longest distance sailed in 24 hrs.

[8] Mari-Cha IV gained particular distinction in 2005, when she broke the 100-year-old record for fastest monohull Atlantic crossing under regatta conditions (as opposed to solo runs, where the team can wait for optimal weather projections), previously established by Atlantic under Charlie Barr during the 1905 Kaiser's Cup.

During the 2005 Rolex Transatlantic Challenge she beat out Maximus for line honours and set the new record of 9 days, 15 hours, 55 minutes and 23 seconds.

[9] In July 2004, the yacht also won the record for the fastest passage from the US west coast to Hawaii.
