They say a couple that plays together stays together.

And when the Duke and Duchess of Cambridge embark on their first official overseas tour to Canada -- and California briefly -- fun will also ensue.

The couple's private secretary, Jamie Lowther-Pinkerton, says Prince William and Catherine's day on Canada's Prince Edward Island will include a race across a lake, and it will be all hands on deck, reported.

Their Royal Highnesses will team up with Dragonboat racers, taking a boat each - although I hasten to add, not themselves paddling, though probably steering - and they will race across the lake to the opposite bank where crowds will be gathered, Lowther-Pinkerton said.

After congratulating the winning team, the couple will be welcomed by First Nations people with a traditional 'smudging' ceremony.

The trip will be the Duchess's first to North America, while William last visited Canada at the age of 15 in 1998 with his father, Prince Charles, and his brother, Prince Harry.

The royal couple are delighted that Canada will be their first tour together and the Canadians have put together an extremely welcoming and well-balanced program of meaningful engagements, mixed with fun and lots of opportunities to get to know Canada and Canadians better, Lowther-Pinkerton said.
