Prince William and Kate arrived in Portsmouth where they attended the America's Cup World Series for the second year in a row. The Duke and Duchess of Cambridge were lucky enough to watch the races, which were postponed last year due to bad weather, on Sunday.
William and Kate donned matching British team tops for the engagement in Portsmouth, with the Duchess still managing to maintain her famous sense of style with an elegant pair of cream wedges.
The royals were greeted by Land Rover BAR Chairman Sir Charles Dunstone, CEO Martin Whitnash and board member Sir Keith Mills, and made their first stop with a tour at the boatshed where they saw the team's progress with their state-of-the-art testing boats.

Kate and Prince William met several young people involved with the 1851 Trust
William and Kate, both 34, then headed to the America's Cup World Series Race Village to meet the teams competing in the race and young people involved with the 1851 Trust. Kate is Royal Patron of the 1851 Trust, which is supported by Ben Ainslie Racing.
Speaking about winning their previous two races on Saturday, Ben, who has just welcomed a baby girl, said: "We wanted to perform well in front of the home crowd to give them something to cheer for - it's an extra impetus. We've been training hard, preparing thoroughly and the guys are really fired up for it.
"We fought hard and kept going to come away with two wins; and to top the day in such difficult conditions at our home event was a great effort."

The highlight of the day was no doubt watching the teams take to the water. Kate, an avid sailor who has sailed with Sir Ben on previous occasions, looked completely engrossed by the action.
She last visited the headquarters of 1851 Trust in May, where she learned about projects which are inspiring young people to take up sailing.

It was then that Kate, 34, said she hoped her children Prince George and Princess Charlotte would follow in her footsteps and take up sailing.
The patronage is a fitting choice for the Duchess, who crewed a yacht on a round-the-world trip during her gap year.
Sir Ben also told HELLO! that he was impressed by Kate's sailing skills. "She's clearly done a fair amount of sailing before," he said, following their outing in May. "She had a feel for the boat. It's a really high powered racing machine and to be able to steer one of those at close to 40 mph for even a skilled sailor is a real challenge and she did a great job. We had a wonderful sail."
