🔍 Key Concepts

• Rule 34 – Maneuvering and Warning Signals (International Rules) • Difference between signals of action (what you are doing) vs signals of intent (what you plan to do) • Special sound signals used in narrow channels for overtaking situations

💭 Think About

• Ask yourself: Under the International Rules, in which situations are whistle signals used to indicate what you plan to do, rather than what you are already doing? • Look at each option and decide: Is this situation normally covered by the standard short blast maneuvering signals, or by the special narrow channel overtaking signals? • Which option specifically matches the International Rule where one vessel announces its planned maneuver and waits for the other vessel’s agreement before proceeding?

✅ Before You Answer

• Verify in Rule 34 (International) which situations use one, two, or three short blasts, and whether those are signals of action or intent. • Check the subsection on narrow channels and overtaking and note which vessel must sound a signal of intent and what kind of response is required. • Make sure the option you pick describes a situation where agreement from the other vessel is required before carrying out the maneuver.
