USCG Exam Practice · Rule 15 — Crossing Situation

Vessel A is a power-driven vessel proceeding on a steady course. Vessel B, also power-driven, is crossing from Vessel A's port side so as to involve risk of collision. Which statement correctly describes the situation?

  1. AVessel A is the give-way vessel because Vessel B is crossing her course
  2. BVessel B is the give-way vessel because she has Vessel A on her starboard side✓ correct
  3. CVessel A is the give-way vessel because she has Vessel B on her port side
  4. DBoth vessels share equal responsibility to maneuver

Why B is correct

Vessel B is approaching from Vessel A's port side, meaning Vessel A is on Vessel B's starboard side. Under 33 CFR §83.15(a), the vessel which has the other on her starboard side is the give-way vessel, making Vessel B the give-way vessel.
