ST. THOMAS — Puzzling out the best course of tactics in the face of continually shifting winds paid off for Malta’s Richard Schultheis on Friday in the opening day of sailing at the 27th annual International Optimist Regatta.

The 14-year-old Foley, who represents the Malta Young Sailors Club based in San Pawl il-Bahar, Malta, finished four races with nothing lower than a third-place score.
