1. GREENWICH REACH GREENWICH SHIP TIER ISOPHASE LIGHT TRIAL - On or about 12th March 2019, for a period of approximately two weeks, the light characteristic of the outer lower wing buoy of Greenwich Ship Tier will be changed from the current Fixed Blue light to Isophase Blue 1s. This change is indicated in the chartlet. This trial is being undertaken to assess whether an alternative light characteristic will improve visibility of the Greenwich Ship Tier mooring buoys as well as other mooring buoy locations. Reports from vessel masters and operators on the effectiveness of the alternative light characteristic should be made to the Upper District Harbour Master (hmu@pla.co.uk).
2. WOOLWICH REACH (UPPER) - ISLAND JETTY - REPOSITIONED CARDINAL MARK - This Notice supersedes M90 of 2018.

On completion of the installation of piles, the South Cardinal Mark will remain in position until the arrival of the new pontoon.
