Brief and debrief.

Before beginning a maneuver that requires the crew to participate (such as docking, anchoring, reefing or changing a sail, tacking or jibing, coming alongside another boat, etc.), brief everyone who will be involved about what you plan to do and what each person is expected to do. Explain things well in advance of the maneuver so people don’t have to rush around at the last minute to get ready. After completing the maneuver, review what each of you did well and what might have been done better. It’s good for learning and for crew cohesiveness. It’s even good to brief and debrief yourself if you’re single-handing.
