Rule 10 Traffic separation schemes. - This means that a ferry crossing from Boulogne to Dover would not give way to vessels in the north east bound lane, but would give way to the south west bound traffic. The reason this is important is that it is easy to assume that crossing traffic will give way to vessels in the lanes, then place yourself in a position where one of the vessels need to turn in to., Rule 9 Narrow channels. - A yacht travelling down a channel, half a mile wide, would probably not consider itself to be in one of these., Rule 8 Action to avoid a collision. - if the other crew are in doubt as to your intentions, they may behave unexpectedly. So a prudent skipper who gives way will make the situation very clear to the other vessel., Rule 7 Risk of collision. - The best practice is to assume that there is a risk until it is proven otherwise., Rule 13 - This Rule also means that a vessel on starboard tack, which is overtaking a vessel on port tack, is the give way vessel. For the same reason a sailing vessel overtaking a power-driven vessel, is also the give way vessel., Rule 34 - Three short blasts indicate that a vessels engines are going astern, she may be reversing or slowing down.,

These are examples of the rules 7 to 10, 13 and 34. Which rule do they exemplify?
