Beyond the harbor, spray is thrown high into the air as waves strike the enclosing reef. The crash of the surf on the coral alternates with a long, drawn-out hiss as each retreating wave regroups to try again. From the vantage of the pier, several breaks in the reef are visible, but it would take an experienced and daring captain to attempt them.
