The UK Maritime & Coastguard Agency has published two guides that Steamship Mutual has said would “be very useful for many Members”.
Marine Guidance Note 349. Navigation: Use of Electronic Navigation Aids
- Be aware that each item of equipment is an aid to navigation.
- Be aware of the factors which affect the accuracy of position fixing systems.
- Appreciate the need to cross check position fixing information using other methods.
- Recognise the importance of the correct use of navigational aids and knowledge of their limitations.
- Be aware of the dangers of over-reliance on the output from, and accuracy of, a single navigational aid.
MCA said that the accuracy and functionality of electronic aids to navigation had increased considerably in recent years. However MCA warned that there was still a danger that over-reliance on the output from a single item of equipment might lead to an accident.
It said that the need to cross-check the vessel’s position using other means was “as important today as it ever was, as is the basic requirement under Rule 5 of the International Regulations for Preventing Collisions at Sea, 1972 as amended, known as COLREGS, to maintain a proper lookout”.
MCA noted that accidents had occurred with ships equipped with the best of equipment where watch-keepers had been over-reliant on the equipment output, and disaster could have been averted by the simple expedient of maintaining a proper lookout.
