The Yachtsman is another Treadstone operative, and so nicknamed due to his affinity for boating. During the attack on Treadstone by Fritz Koenig and the traitor Gillette, the Yachtsman actually manages to get to one of the rooms and arm himself with a revolver. Not that it does him much good, as the minute he has the thing in his hand, Koenig enters and the Yachtsman becomes the third and final victim of Koenig's Walther PPK.
