You need to know how your boat will react, its turning circle and any predictable quirks to its handling. There will be some close quarters manoeuvring, usually in a harbour, to demonstrate your skills at berthing and leaving pontoons, piles or moorings. Sailing yachts will complete this section under power, but make sure you practice manoeuvring under sail too, picking up mooring buoys and short tacking. Your examiner isn’t looking for first-time-every-time success, but you will need to demonstrate competence and a good understanding of how the boat reacts at slow speed. Don’t hesitate to change sails or reef, if you think it is necessary for the task. Experience in a variety of conditions will be your biggest help in these situations.
