The Bosphorus Cup is a prestigious international sailing regatta held annually in Istanbul, Turkey, where competitors race through the iconic Bosphorus Strait that divides Europe and Asia. Founded in 2002, the event has grown into one of the region’s premier yacht races, attracting top sailors from around the world. Its unique setting—navigating narrow waters between historic landmarks with commercial traffic halted—makes it one of the most visually stunning and technically challenging races in the sport.
