🔍 Key Concepts

• Rule 15 – Crossing Situation: Which vessel must keep out of the way when two power-driven vessels cross? • Relative position: From each vessel’s viewpoint, is the other on the starboard or port side? • Sound signals for maneuvers (one short blast) under International & Inland Navigation Rules.

💭 Think About

• From Vessel A’s bridge, where is Vessel B located: on A’s starboard bow or port bow? How does that affect A’s responsibilities in a crossing situation? • From Vessel B’s bridge, where is Vessel A located? Based on Rule 15, which vessel should normally maintain course and speed? • Does the one short blast change who is stand-on or give-way, or does it only indicate the maneuver the vessel intends to make?

✅ Before You Answer

• Confirm which vessel has the other on its starboard side – that vessel is normally the give-way vessel in a crossing situation (Rule 15). • Verify that neither vessel is coming up from more than 22.5° abaft the beam; this rules out an overtaking situation (Rule 13). • Remember that sound signals describe an intended maneuver; they do not change which vessel is stand-on or give-way under the Rules.
