Olympic sailing champions Iain Percy and Andrew "Bart" Simpson (right) were childhood friends and enjoyed their greatest successes together.
Simpson tragically died two years ago during a training exercise in San Francisco Bay for the 2013 America's Cup, as a crew member for Percy's Artemis Racing entrant.
The high-speed AC72 capsized, trapping Simpson under the hull. Here a crane lifts the stricken vessel out of the dock.
The British duo won gold in the Star class at Beijing 2008 while close friend Ben Ainslie (far right) -- now Percy's America's Cup rival -- triumphed in the Finns.
Percy says Simpson's Olympic spirit remains a major driving force to everything Artemis Racing does in the America's Cup.
Percy admits he is still struggling to get over the tragedy, two years on from cradling a dying Simpson in his arms.
