During the first minutes of Oct. 25 when Hurricane Otis roared into Acapulco Bay with 165 mph winds, sailor Ruben Torres recorded a 10-second audio message from a yacht called the Sereno. The Sereno was one of 614 boats — yachts, ferries, fishing boats — that according to Mexico's Navy were in the bay that night and ended up damaged or on the ocean floor. Of those aboard the Sereno, one person survived, while Torres and the boat’s captain remain missing.
