Denise "Dee" Caffari MBE (born 23 January 1973) is a British sailor, and in 2006 became the first woman to sail single-handedly and non-stop around the world "the wrong way"; westward against the prevailing winds and currents.

[1] In February 2009, Caffari completed the Vendée Globe race and set a new record to become the first woman to sail solo, non-stop, around the world in both directions.

Dee managed one serious situation when a crewmember needed to be airlifted off in the Southern Ocean by the New Zealand Rescue Service due to an abdominal infection.

[18][19][20] In January 2007 Caffari announced that she would be taking part in the 2008/09 – Vendée Globe singlehanded round the world yacht race, again sponsored by Aviva.

[22] In December 2007 she had to be rescued by Royal Navy frigate HMS Northumberland after dismasting in severe weather off northwest Spain whilst competing singlehanded in the Transat Ecover B2B Race.

In March 2009, Caffari's autobiography Against the Flow was re-published in paperback with an additional chapter charting the lead up to her Vendee Globe entry and subsequent world record achievement.
