Portsmouth Small Boat Channel

Changes to Portsmouth Small Boat Channel

Due to dredging and changes to the entrace to Portsmouth harbour, the small boat channel has changed position.

Mariners are firstly advised that following the widening and re-orientation of the Portsmouth Approach Channel, as depicted on the newly published Admiralty Chart 2625 (2 March 2017), further adjustments have been made to the positioning of the Small Boat Channel that runs between 4 Bar Buoy (50 46.97N 001 06.48W) and Ballast Pile (50 47.62N 001 06.83W).

This latest Notice to Mariners supersedes LNTM 23/17 (Small Boat Channel Re-alignment) and should be read in conjunction with the regulations contained in General Direction 7/10 (Portsmouth Harbour Entrance – Approach Channel, Small Boat Channel, Swashway and Inner Swashway).
