🔍 Key Concepts

• Rule 18 – Responsibilities Between Vessels (International & Inland) • The "pecking order" of vessels: Not Under Command, Restricted in Ability to Maneuver, Fishing, Sailing, Power‑driven • The meaning of the phrase "Unless the rules require otherwise" (think about overtaking, narrow channels, etc.)

💭 Think About

• First, recall where sailing vessels fall in the hierarchy compared to vessels engaged in fishing and ordinary power-driven vessels. • Ask yourself: does a pilot vessel on station automatically outrank a sailing vessel under Rule 18, or only when it meets some other definition (like Restricted in Ability to Maneuver)? • Think about whether a vessel that is overtaking is usually required to keep clear of the vessel being overtaken, or if the vessel being overtaken must keep clear.

✅ Before You Answer

• Verify under Rule 18 which categories a sailing vessel must keep out of the way of in both International & Inland rules. • Check whether a vessel engaged in trawling is considered a vessel engaged in fishing under the Rules hierarchy. • Confirm who has the obligation in an overtaking situation: is it the overtaking vessel or the vessel being overtaken that must keep out of the way?
