Chris Duff is an American expedition sea kayaker, who is most notable for his large scale projects and world-record breaking attempts. Since 1983, he has kayaked over 14,000 miles.

Chris Duff is very famous for many of his endurance kayaking expeditions, including circumnavigation of Iceland; and solo circumnavigation of New Zealand and Ireland. He has also broken world records for being the first person to circumnavigate Great Britain alone. When asked why he chooses to partake in these solo expeditions, he replied:

There are very few times in our busy lives where we have the luxury of true solitude. I love the simple focus of these journeys; the physical challenges of the sea balanced by the inner calm which comes from living purposefully and so simply.

In May 2012, Chris successfully crossed the Atlantic between the Outer Hebrides and the Faroe Islands, as part of a journey to Iceland in his kayak.

In 1999, Chris Duff decided to circumnavigate the south island of New Zealand. He began preparations on 29 November 1999 but did not start his voyage until 5 December 1999. Despite being considerably shorter than many of his other routes, at around 1700 miles, this journey is viewed as particularly demanding due to its location in the Roaring Forties.
