Kate Middleton has given her backing to British Olympic sailor Ben Ainslie's America's Cup bid.

The Duchess of Cambridge is the patron of 1851 Trust, a charity set up by Ainslie's sailing team which provides nautical education for young people.

Middleton helped open the Trust's new education center in Portsmouth, in the south of England. The center -- called the "Tech Deck" -- features exhibitions on the science behind America's Cup engineering.

The Duchess then strapped herself in for a ride on Ainslie's 45-foot catamaran.

Ainslie was testing the yacht ahead of the Louis Vuitton America's Cup World Series in Portsmouth, in late July. The two-day racing event is a build-up for next year's America's Cup Challenger series

Middleton, a keen sailor, helped with the rigging while the yacht sliced through waves at around 38 mph (61 kilometers per hour).

The training session took place on the Solent, a strait of water separating mainland England from the Isle of Wight, and where the original America's Cup race set sail in 1851.

Ainslie launched his own multi-million dollar America's Cup bid in 2014, vowing to bring the trophy back to UK soil for the first time in 165 years.

Middleton has since been a high-profile patron of Ainslie's sailing team.
"You can tell she has done a lot of sailing, she was a natural on board," said Ainslie of the Duchess.

With Middleton on board, Ainslie has been testing one of his team's development yachts -- a foiling AC45 catamaran.
