1. Automatic Identification System. It’s an automatic communication system in which each vessel transmits information such as its course, speed, and size to, and receives the corresponding information about other vessels around it.
2. Twenty to thirty minutes. According to the specialist report commissioned after the Ouzo collision, our eyes use two types of light sensors. The once we use most adapt relatively quickly, so we think we have got out “night sight” after about five minutes. But the other kind, which adapt more slowly, are better in low light. And they don’t adapt for at least another quarter of an hour. So the total is twenty to thirty minutes.
3. Compass bearings or True bearings, but not relative bearings (or wheel bearings!)
4. The colregs don’t tell you when you should switch your navlights off: they only specify that they must be kept on between sunset and sunrise and in restricted visibility
5. Wing in Ground Effect Craft – a sort
of low-flying aircraft. The funny thing is that although they were
developed during the Cold War, and only a handful of them still exist
in the entire world, they have only just appeared in the latest
revision of the rules. 6. A GPS-assisted collision
Score three points for anything along the lines of “the OOW was distracted”
Add a bonus of two points if you got that he was distracted because he was telling the Captain that he had collided with a fishing boat fourteen minutes earlier.
