🔍 Key Concepts

• International Regulations for Preventing Collisions at Sea (COLREGS) – Maneuvering and warning signals • Difference between intent to maneuver and actual alteration of course • Rule 34 – Manoeuvring and warning signals (international vs inland wording)

💭 Think About

• In international waters, does one short blast describe what the vessel is planning to do, or what it is physically doing right now? • Is the signal about the relative passing arrangement between two vessels (port‑to‑port vs starboard‑to‑starboard), or about the direction of the vessel’s course change? • Compare the wording used in Inland Rules for one short blast with the wording used in International Rules – what single word changes the meaning?

✅ Before You Answer

• Confirm you are thinking INTERNATIONAL ONLY, not Inland – the meanings differ slightly. • Check whether the rule text says "I am altering" or "I intend to alter" course to starboard. • Make sure the option you choose refers to the vessel’s course change direction, not a specific side‑to‑side passing arrangement.
