John Kostecki is one of the most successful sailors in the world with an around the world race victory, an America's Cup win, and an Olympic medal. He grew up sailing on San Francisco Bay and is very familiar in these waters. Throughout the race Kostecki constantly grinds one of the winches to power the hydraulics, and help trim the sails. It is hard, exhausting work. Over on the New Zealand boat, the tactician Ray Davies, does not have grinding duties. He looks around and studies the wind, the current and his boat's performance versus that of Oracle’s. As a former America's Cup tactician I like to listen to them and watch their performance. Of course it is easy for me as a television commentator to critique their moves, but I think the physical work for Kostecki (who is 49) might be hurting his ability to look around.
