Local notices to mariners

Local notices to mariners

See our local notices to mariners to find out about how events in the harbour may affect you.

Local notices to mariners contain important information on:

  • temporary navigational directions and/or restrictions
  • notification of water events in the harbour

The notices have two digits each for the number of the notice and the year it was issued, for example Notice No 41/10 means notice 41 of the year 2010.

You should check these events as they're in force for the safety of all harbour users and will help you make the most of your visit to Bristol Harbour.
