State the purpose of the Pilot Card
The pilot card, to be filled in by the master, is intended to provide information to the pilot on boarding the ship This information should describe the current condition of the ship, with regard to its loading,
propulsion and maneuvering equipment, and other relevant equipment.
State the general topics of information that should be contained in the recommended Wheelhouse Poster
The wheelhouse poster should be permanently displayed in the wheelhouse. It should contain general particulars and detailed information describing the maneuvering characteristics of the ship, and be of such a size to ensure ease of use. The maneuvering performance of the ship may differ from that shown on the poster due to environmental, hull and loading conditions.
State the seven sections of the Maneuvering Booklet
Recommended information to be included in the maneuvering booklet
1.General description
2 Maneuvering characteristics in deep water
3 Stopping and speed control characteristics in deep water
4 Maneuvering characteristics in shallow water
5 Maneuvering characteristics in wind
6 Maneuvering characteristics at low speed
7 Additional information
Current Maritime and Coastguard Agency guidance warns of the Dangers of Interaction.
State the key points of the Maritime Guidance Note on this subject
Key Points:-
Understand that sudden sheering may occur when passing another vessel at close range
Appreciate the need to reduce speed in narrow channels
Be aware of the dangerous effects on tugs when manoeuvring close to larger vessels
Be aware that unexpected turning moments may result when stopping in shallow, confined basins
Appreciate the need to make appropriate allowances for squat
