Navigation is subject to Collision Regulations and bye-laws made under the Bristol Docks Act and any latest amendments. The whole of the City Docks should be regarded as a narrow channel.

The speed limit for pleasure craft is 6mph unless special permission has been obtained from the Harbour Master.

Attention is drawn to the risk of collision at the approaches to all bridges. Vessels should sound one prolonged blast before going through any bridgeways.

Powered vessels should slow down when passing pleasure craft moorings, sailing dinghies, canoes or rowing boats. As a general rule, a vessel should not be going so fast as to cause a breaking wave.

Floating Harbour and Feeder Canal

The Floating Harbour and Feeder Canal are open for navigation by day and by night, although Netham Lock at the far end of the Feeder Canal is closed at night.

The Floating Harbour is frequently dredged to maintain water depth. Dredgers display the signals prescribed in the Collision Regulations. Do not pass on the side of a dredger on which there is displayed two black balls or two red lights in a vertical line. Vessels should proceed on the side of two green lights or two diamonds in a vertical line.
