The 117th Chicago Yacht Club Race to Mackinac presented by Wintrust once again demonstrated the scale and competitive depth that have established it as the largest annual offshore race in the world. The 333-mile course–spanning the length of Lake Michigan–challenged 250 teams with nearly the full spectrum of offshore sailing conditions, from upwind and downwind racing to heavy air, tactical light winds and powerful overnight thunderstorms. As the race unfolded, teams navigated rapidly changing conditions across Lake Michigan. Early upwind sailing pushed much of the fleet toward the Michigan shoreline, but the wind later shifted nearly 180 degrees, transforming the race into a downwind contest. The dramatic shift created a complex tactical transition, rewarding teams that anticipated the changing breeze and positioned themselves to take advantage of the new conditions. Late Sunday and into early Monday, a line of strong thunderstorms swept across northern Lake Michigan, bringing reported winds exceeding 35 knots and disrupting teams’ strategies as they raced toward the Straits of Mackinac. Despite a number of retirements, all competitors were accounted for and safe. Fourteen J/111s competed in a one-design division, won by Scott Sellers’ No Surprise. George Golder’s Terrier and Jeff Davis’ Shamrock rounded out the top three. Complete race results are available at Chicago Yacht Club
