Crossing situation in traffic separation scheme (vessel A using traffic separation scheme has vessel B on her own starboard side)

  • Description of scenario: Vessel A: power-driven vessel using traffic separation scheme
    Vessel B: power-driven vessel of 20 m or more in length crossing traffic separation scheme
    Area: Traffic separation scheme
    Visibility: Good (Vessels in sight of one another)
    Vessel A and vessel B are crossing so as to involve risk of collision
    Vessel A has vessel B on her own starboard side
  • Rule(s) to be applied: Rule 10 (Traffic separation schemes)
    Rule 15 (Crossing situation)
    Rule 16 (Action by give-way vessel)
  • Applying the Rule(s) and comments: In accordance with Rule 10 (c) (Traffic separation scheme), a vessel (vessel B) shall so far as practicable avoid crossing traffic lanes, but if obliged to do so shall cross on a heading as nearly as practicable at right angles to the general direction of traffic flow.
    In accordance with Rule 15 (Crossing situation), when two power-driven vessels are crossing so as to involve risk of collision, the vessel (vessel A) which has the other (vessel B) on her own starboard side shall keep out of the way.
    In accordance with Rule 15 (Crossing situation), vessel A shall, if the circumstances of the case admit, avoid crossing ahead of vessel B.
    In accordance with Rule 16 (Action by give-way vessel), every vessel (vessel A) which is directed to keep out of the way of another vessel (vessel B) shall, so far as possible, take early and substantial action to keep well clear.
