Take 10: Issue 2
This issue of The Navigator has looked at the Colregs and the whole area of avoiding collisions at sea with them. Here are ten points that everyone can take away to help keep this crucial topic at the forefront of the mind.
1 Keep an eye out
In over 50% of collision cases, either one or both vessels didn’t see the other before it was too late – often in good visibility!
2 The eyes have it
Despite the availability of modern electronic tools, visual sightings and experience are superb for avoiding collisions – and don’t forget to look astern.
3 Experience is key
Knowing the rules of the road is essential. However, applying them correctly and consistently requires much experience.
Always try to learn from each experience; work with others to share your knowledge and discuss incidents (yours or others) as a team at safety briefings.
4 Nobody’s perfect
Humans (including navigators) are not 100% infallible. When available, take advantage of additional support. Use lookouts as appropriate and call the Master whenever in doubt.
5 Professional lookouts
Lookouts are professional mariners and can save the ship from disaster. Treat them with professional respect, encourage them to look at the radar and confirm all reports.
6 Other people’s shoes
Courtesy and putting yourself in the position of the other vessel can, in many instances, avoid the risk of collision ever arising in the first place.
7 Be defensive
Never assume that a ‘give way’ vessel will see you, act in accordance with the Colregs, or share your understanding of ‘safe distance’. And never assume that a ‘stand on’ vessel will see you, maintain their course and speed or share your understanding of ‘safe distance’.
8 All available means!
The Colregs require you to use ‘all available means’ to determine the risk of collision. This includes your own senses, a wide range of electronic instruments, and shore support when available. Use them all, and use your imagination.
9 Stay out of the fast lane
Reducing speed is an essential tactic for reducing the risk of collision, both in a specific incident and generally in congested waters. Ensure you are familiar with how your vessel reacts to reducing speed and encourage others to be aware of its effectiveness.
10 Plan ahead
Risk of collision can often be anticipated during passage planning. Alter the plan to reduce such risks and/or ensure that enough crew are available during risky areas, and that the ship is making safe speed..
