- The steering mode selected was appropriate to the area being transited.
- Under keel clearance was suitable for the draft of the vessel at all times.
- Course changes were made in accordance with the voyage plan.
- The vessel’s position was fixed and plotted on an appropriate chart at intervals suitable to the vessel’s speed and the area being transited.
