On top boats, the dialogue while racing will typically involve four key people: the tactician, helmsman, mainsail trimmer, and jib trimmer. Granted, not everyone has the luxury of sailing with a great helmsman, trimmer, and tactician, and on a lot of boats, crewmembers have multiple roles. The helmsman, for instance, might also trim the main, or the jib trimmer might call tactics. But for our purposes, we’ll split up the roles, with each person focusing on a single aspect of getting the boat around the course as quickly as possible. Now, let’s go through a maneuver. Imagine yourself on an upwind leg, on port tack, encountering a starboard tacker. Here’s what you might hear as the boat prepares for and then dips the starboard-tack boat.
