1. The ‘Keel walk’

Alex Thomson made one of sailing’s most iconic images when he was photographed walking the keel of his yacht Hugo Boss.

Getting the conditions right for the keel walk wasn’t simple. It took 18 knots of wind, a slight sea state, a precise sailing speed and a cool-headed skipper to perfome the stunt on the 8-tonne yacht.

“We’d wake up one day and the conditions would look just right,” he said, “so we’d sound the alarm and get the boat prepped, bring in the jet ski guy, the RIB driver, the photographer, the camera guys… I’m in the suit, ready to go…and the wind drops. It was hurry up and wait, hurry up and wait.”

3. Freerunning on a Volvo 65

Parkour athletes Jason Paul and Pasha Petkuns try their first ever freeruning session at sea- onboard the Volvo 65 Team Brunel.

This picture was taken last year in Newport, Rhode Island, during a Volvo Ocean Race stopover. The duo swung from a halyard off the 30m high rig: “It’s a trick you see people do with smaller sailboats – but this takes it to a whole new level,” Paul said.
