I am confused about the definition of the Transatlantic speed record.
According to the World Sailing Speed Record Council
(sailspeedrecords.com), the Mari-Cha IV set a Transatlantic record of 6
days 17 hours in October 2003. But last month they set another
Transatlantic record of 9 days 15 hours, breaking the longstanding
12-day record set in 1905 by the 185-foot Atlantic. What is the
difference between the two Mari-Cha records? It appears that there is
perhaps a distinction between a "passage record" and a "crewed record",
but I cannot find any such terminology in the WSSRC rules. Can somebody
please shed some light on this?
