Rule 15 - Crossing Situation

Plain English for Cadets

If two ships cross paths and there’s a risk of collision:

• The ship that sees the other ship on its starboard side is the Give-Way Vessel.

• The Give-Way Vessel must act early — usually by turning to starboard.

• Avoid passing ahead of the stand-on ship.

• The ship with the other on her port side is the Stand-On Vessel — keep your course and speed, but be ready to act if the give-way vessel fails to.

Key Bridge Advice for Cadets

• Ship on Starboard = Stand On. If the other vessel is to starboard, you give way.

• Act Early and Boldly. Small alterations cause confusion.

• Starboard Turn is Best. Don’t cross ahead.

• Keep Checking Risk. Use radar, visual bearings, and ARPA if fitted.

• Call the Master Early. If unsure or action looks late, call the Captain.
