To prevent crossflow of wind and increase aerodynamic efficiency of boom-footed sail, a stationary sealing vertical baffle structure is mounted along the centerline of a sailboat under the boom. The top portion of the baffle is made of a compliant sealing material, e.g., closed cell polyurethane foam, which forms a tight seal with the boom when the boom is positioned substantially along the centerline, as is common when sailing to weather. The boom and baffle can have curved side surfaces which form with the sail a substantially continuous surface which extends the effective sail area down to the deck.
