Mari-Cha IV

Mari-Cha IV is the largest racing yacht afloat in the world today.

The aim was to create the fastest monohull designed for offshore courses. In addition she had to be easy to sail manually and without assistance.

Built from a very light all carbon structure, she is very distinctive and features a canting keel which cants at +/- 40°. She has a divided sail plan, with two equal masts, enabling the crew of 25 to handle the sails manually.


She broke the Transatlantic Record in 2003, making the crossing in 6 days, 17 hours, 52 minutes, at an average speed above 19 knots. Her best distance in one day was 525 miles

In 2005, she won the Rolex Cup, fleet race run over the Atlantic from New York to Lizard Point.
