Sir Ben Ainslie is trying to sell his AC45F foiling catamaran as the America's Cup takes a new route.

Fancy owning an America's Cup catamaran? Got a spare $200,000? Then Sir Ben Ainslie is looking for you.

The boat is a proven winner and has even been sailed by British royalty.

Ainslie is selling the AC45F he used to win the 2015-16 America's Cup world series.

Catherine, the Duchess of Cambridge, a yachting enthusiast and friend of Ainslie's, got on board the boat in 2016 as Ainslie's team trained in the middle of the nine-event world series.

The boats are redundant now in terms of the America's Cup which has returned to monohulls in 75-foot foiling versions determined by new cup holders Emirates Team New Zealand.

The 45-foot catamarans were modified to foil and Ainslie claims it has a top speed of 38 knots.

"Own the ultimate America's Cup flying machine" is the tease on his team's website as they plug the sale of the carbon-composite catamaran that is listed in "excellent" condition.

The complex boat features a 20m wingsail and comes with a full array of accessories.

The asking price is £100,000 ono, though the new owner will be up for taxes, duties and transport.

Ainslie's team are burying themselves in design work for their new America's Cup monster and are the first syndicate to test a smaller 28-foot version of the foiling monohull.
