Today, Kate was back, this time with William, to support Ben Ainslie once again. The America's Cup was first staged in 1851 off the Isle of Wight. It is international sport's oldest trophy.

Today's event was delayed because of bad weather in Portsmouth. According to their website they said:
"Due to the weather forecast for winds in excess of 30mph to come in during the original racing window of 13:30 to 15:00 hrs today, Sunday 26th July, the Regatta Director has decided to bring forward with a scheduled start time of 1200 noon."

The Duke and Duchess arrived in plenty of time for the races and to meet the teams beforehand. They spoke to Emirates Team New Zealand, who they first met last year during their visit to New Zealand.

According to The Mirror they also met "Sir Keith Mills, Chairman of The Louis Vuitton America's Cup World Series Portsmouth, Donna Jones, leader of the Portsmouth City Council, and a few other key dignitaries."
The Duke and Duchess watched the race from inside, due to the bad weather.

However, the race was stopped half-way through because of bad storms. Kate's disappointment was obvious as the boats were dragged back into the harbour.
