"This makes Bob Miller's new Mari-Cha the first sail-powered monohull to
break the 500-mile, 24-hour barrier. If the record is ratified by the World
Speed Sailing Record Council (http://www.sailspeedrecords.com/), it will
displace the previous record of 484 miles in 24 hours, set by the Volvo 60
Illbruck in the North Atlantic in April, 2002. For scale, remember that
Tracy Edwards and the crew of the big cat Maiden 2 hold the outright 24-hour
record, sailing 694.78 nautical miles at an average speed of 28.95 knots in
mid-Atlantic in the summer of 2002."
