The Duke of Cambridge climbed into the cockpit of a Sea King helicopter for the military training exercise at Dalvay by-the-Sea, a scenic resort along Prince Edward Island's north shore. Prince William, a Royal Air Force rescue helicopter pilot, requested the simulated emergency landing procedure.
Dressed in an olive flight suit and helmet, the prince settled the large helicopter on the water several times over the course of an hour.
From the water, William piloted several takeoffs and hovered in the air before executing dual- and single-engine landings before taxiing around as Kate watched from the ground.
"He was looking for his wife on the shoreline at one point," said Col. Sam Michaud, 42, who trained William. "She was waving back about 100 feet away."
Michaud said William was now fully trained. He said William remarked that the "boys back at his squadron would be absolutely jealous."
Canada is the only country that trains its Sea King helicopter pilots to do a controlled landing on water if there's an emergency. The exercise William performed is known as waterbirding, and if the number of times he tried it was any indication, the prince was enjoying the technique. The Sea King, which William flies back in the UK, has the ability to land on water because of its amphibious hull.
Maj. Pat MacNamara called him a star pilot.
"I would suggest he was having quite a bit of fun," MacNamara said. "He said it was one of the highlights of his trip."
Prince Edward Island resident Linda Patton, 60, said she was nervous watching the prince fly.
"It was thrilling to watch and a little nerve-wracking I must admit, especially the ones he was hovering and came straight down" Patton said.
The royal pair then got to flex their muscles by paddling in two dragon boats to race against each other. Kate, dressed in black sportswear, got to demonstrate her athletic prowess while on the water by taking the stern of her boat. She trained as part of a dragon boat crew in 2007, and the rivalry with William appeared to be genuine.
William gripped his paddle to execute a strong stroke, while Kate moved from the stern to paddle in her boat. The prince's boat won the short race by a hair and William exited the boat to give Kate a warm consolation hug. Kate laughed and tried to push William in the water.
Later, the royal couple met an actress who plays the fictional star of Anne of Green Gables, the classic Canadian novel for which Prince Edward Island is famed. Actress Tess Benger, 23, who performs as Anne in a play, gave Kate a copy of the book. Kate, a fan of the novel, told her she would read it again.
In a tent, the couple sampled the island's food. William put his hands on his stomach and joked about eating too much on the trip. He passed on the oyster tasting, saying to Kate "this is where you take over."
They tasted Island beef with sweet onion marmalade, lobster and potato chowder, pork and beef belly and strawberry shortcake. The couple later observed a search and rescue operation.
The Duke and Dutchess of Cambridge, as they are officially known, were on the fifth of a nine-day trip to Canada, part of their first official overseas trip since their April 29 wedding.
They were welcomed to their third Canadian province on Monday with cheering, waving crowds excited to catch a glimpse of royalty at Province House. The site is the home of Prince Edward Island's legislature and of a historic meeting 146 years ago that paved the way for Canada's eventual unification and independence.
On Monday morning, Kate sported a cream dress by Sarah Burton at Alexander McQueen, who designed the wedding gown she wore. William wore his traditional dark suit and red tie. Kate later wore dark skinny jeans and a navy-belted trenchcoat with a bright red scarf from Burton's wardrobe at Dalvay-by-the-Sea.
For the third time during the trip, William spoke in French and English to address the crowds.
"We have both so looked forward to this day, and discovering more about your beautiful island," he said.
The royal pair delighted the several thousand people gathered at the site by walking over to shake hands and stop for a quick chat, while some handed them flowers, including the east coast Canadian flower, Lupins, and hand-held Canadian flags, while snapping photos.
The smiling couple hopped into a landau led by Canadian Mounties to take them to Confederation Landing for another walkabout before heading to the resort at Dalvay by-the-Sea.
The royal pair next head to Yellowknife, capital of the sparsely-populated Northwest Territories. They leave for a three-day trip to California on July 8.
