Self-Spotting – Cote Ste Catherine Lock

The Great Lakes-St. Lawrence Seaway issued a notice to shipping regarding a self-spotting system that has been installed at the upper and lower end of Cote Ste Catherine lock.
The system is activated for a qualified ship, once the lock personnel confirm the ship passage at the inbound limit of approach no2. Variable message display boards will display the distance between the stem of the ship and the stop position, once the ship is less than 30m from her stop position. The display boards will indicate 999 if the ship is more than 30m from her stop position.

The lock leader will inform the ship if she is qualified and if the self-spotting system is operational, during the initial communication, once the ship is at the limit of approach. The spotting instructions from the lock personnel are to be respected.

Pilots/Masters are asked to convey any comments they have on the self-spotting system to the lock crew. The lock crew will enter your comments on the ‘Self-Spotting Test Form’ created for this purpose. Any and all comments are welcome. Thank you in advance for your cooperation.
