Collision Regs

Quiz question in the last Update:


“Navigational Safety is very important but just as important is our behaviour to and consideration of each other when on the Hamble River. Now it is quiz time. Your 25 foot craft is motoring down the river; as you approach the Hamble travelling downstream; another 25 foot craft emerges, at right angles to the main channel, from the Haven. Neither craft is constrained by its draught. Which vessel has right of way and what action should you take? Answer in the next edition of 'Update'.”


Jason Scott’s (Harbourmaster) Answer:


Many Rules apply to this scenario and in a non-professional environment, it is likely to be true that at least one party will not have a full or current understanding of the Collision Regulations, despite holding a relatively significant qualification (Yachtmaster etc).  The best thing to do is to slow down and give yourself more time to assess the situation, if in any doubt.

It is obvious but worth remembering that the Collision Regulations are designed to reduce the likelihood of collision.  They apply in the River.  In this scenario, we are in a narrow channel.  Both Masters are responsible in accordance with the Rules for collision avoidance and both will be held accountable to a degree in the event of a collision.  The crossing vessel is burdened and should not impede the safe passage of the vessel in the channel by crossing so as to avoid a collision.  The vessel in the channel must stand on.  The crossing vessel must not cross.  If she does and risk of collision exists, she must take early and substantial action to avoid a collision.  The stand on vessel (in accordance with rule 17) may take action to avoid collision by her manoeuvre alone, as soon as it becomes apparent to her that the vessel required to keep out of the way is not taking appropriate action in compliance with the Rules. Nonetheless, the stand-on vessel or vessel required to keep her course and speed must take  such avoiding action  as will best aid to avoid collision when she finds herself so close that collision cannot be avoided by the action of the give way vessel alone.  That manoeuvre will not relieve the give way vessel of her obligation to keep out of the way.
