Prince William has defeated his new wife in a dragon boat race in Canada.
The royal couple were supposed to be steering the teams as they competed on Dalvay Lake, Prince Edward Island.
But when the race began, the Duke and Duchess of Cambridge began rowing the 200ft course along with their team-mates.
William's team crossed the finishing line a third of a boat's length ahead of Kate's.
Race starter Mike Haslam told Sky News: "Before getting into his dragon boat, William changed his mind about being at the helm and told Kate he was going to paddle.
"Kate looked a little taken aback, but at first stuck to her guns. Then she asked me if the helmsman or woman ever fell into the water.
"I told her it is rare. But in the end, just before the race started, she decided to take William on from inside the boat."
Also during the day, William had the opportunity to show off his flying skills as he joined the crew of a Canadian Sea King helicopter.
He demonstrated to a watching crowd, as well as his wife, the practice known as "waterbirding".
It is an emergency manoeuvre used by Canadian pilots if they have engine failure and have to land on water.
Earlier, the pair were welcomed to Charlottetown, the island's capital city, by a piping band.
Sky's royal correspondent Paul Harrison, who is in Canada, said Kate was wearing a cream dress by Sarah Burton, the designer who made her wedding dress.
Mosha Lundstrom Halbert, associate fashion news editor at Canadian fashion magazine Flare, said: "The first thing that struck me was that it had a very nautical feel to it.
"She has taken the settings into consideration nicely. It is simple and chic while quite classic and timeless."
Kate revealed her hopes of starting a family after complimenting the father of a "beautiful" toddler in Quebec.
The Duchess was presented with a bouquet by Raffaela, the two-year-old child of British ex-pat David Cheater, 28, during a walkabout.
And when the proud dad wished the Duchess well in her efforts to start a family, Kate thanked him and said: "Yes, I hope to."
The 28-year-old landscape gardener said: "Kate said to me 'what a beautiful daughter you have'."
It is the first time the royal has spoken publicly about having children although Prince William stated when they got engaged that having babies was something they wanted to do.
The couple's trip now takes them to Yellowknife in Canada's northwest territories and then to Calgary for a rodeo before they go to America.
