The survey was conducted on 24th January 2020 and is the latest hydrographic data available. Mariners are advised to examine the full survey and make any necessary passage planning adjustments. Annual maintenance dredging is expected after April of this year. Any additional surveys before that time will be promulgated via Local Notice to Mariners.

A digital copy of the survey is available online here, with a scale copy available to view in the Sovereign Harbour marina office. The printed notice is available online here.
