🔍 Key Concepts

• Rule 18 – Responsibilities Between Vessels (priority of vessels engaged in fishing vs ordinary power‑driven vessels) • The basic crossing situation rule (Rule 15) about the vessel that has the other on her starboard side keeping out of the way • The definition of a vessel engaged in fishing in Rule 3 and how that affects who is stand‑on and who is give‑way

💭 Think About

• First decide which vessel has the other on her starboard side in this diagram. From vessel A’s viewpoint, where is B located? From vessel B’s viewpoint, where is A located? • Then ask: when one vessel is a normal power‑driven vessel and the other is engaged in fishing, does the usual crossing rule still apply, or is there a different priority rule? • Check if there are any exceptions (like overtaking) shown in the picture that might change the normal priority between a fishing vessel and a power‑driven vessel.

✅ Before You Answer

• Verify from Rule 18 which vessel must keep out of the way when a power‑driven vessel meets a vessel engaged in fishing. • Confirm that this situation is NOT an overtaking situation by carefully looking at the headings shown by the arrows. • Make sure you are not choosing an option that relies only on “port/starboard” without correctly applying the special status of a vessel engaged in fishing.
