Harbour Entrance (The Run)
The entrance to the Harbour is approached from seaward from the Langstone Fairway Pile. Depths of up to 13m exist in the harbour entrance where tidal rates are especially strong. The entrance is marked with a QR light on the short sea outfall at Eastney Point and by 2FR on the jetty 1 cable north.
There are small craft moorings on each side of the main channel north of the Run. At Sword Point the Channel branches into Langstone Channel, running in a NE’ly direction, and Broom Channel, running in a N’ly direction. The depth and width of both channels are severely constrained at their northern end, where large vessels can only navigate between HW-2h and HW+3h.
The northern limit of the entrance channel is marked with two lit buoys. The west side of the navigable channel is marked with East Milton buoy, Fl(4)R.10s and the east side of the channel is marked with NW Sinah buoy, Fl.G.5s. South of these buoys navigable depths always exceed 4m BCD in the channel. Langstone Channel
Langstone Channel is entered from the main entrance channel around NW Sinah buoy, marking the western extremity of Sinah Sands. The channel, which runs in a NE direction for approximately 1 mile and then in a northerly direction for about 0.75 miles, is bounded to the south by Sinah Sands and to the north by Sword Sands. These extensive areas of sand and mud are dry at low water. The limit of navigable depths of over 2m BCD is marked on the stbd side (with mainstream of flood tide) by lit, green, lateral buoys at intervals of approximately 5 cables as follows:

North side of channel where channel changes direction. Paired with RodBedhampton Approach Channel
The north end of Langstone Channel narrows and gives access to the approach channel for Bedhampton Wharf, an aggregate wharf in the far north of the harbour. The channel is approached between lit piles at the southern extremity.
Bedhampton Approach Channel is an artificial channel with a least depth of 1.0m BCD. The direction of the southern part of the channel, which is marked by 6 piles approximately 800ft apart on the west side, is 343(T). A bend in the channel is marked with a lit pile (FL.R) and here the direction of the approach changes to 018o for approximately 3 cables to the turning basin at Bedhampton Wharf.
Two unlit transit markers with triangular topmarks are located north of the channel to mark the initial approach.

Marking corner at north end of approach Broom Channel
The Channel north of East Milton buoy and west of Sword Sands is known as Broom Channel. To the west, the intertidal foreshore dries to 3m OCD. To the east, the first leg of the channel is bounded by Sword Sands and the second leg of the channel (north of Salterns buoy) is bounded by Mallard Sands. These extensive areas of sand and mud dry to 4m OCD.
A small channel known as Russells Lake and used by small recreational craft branches NE from the south end of Mallard Sands at the corner of the main navigable channel. The south end of Mallard Sands is marked by an unlit South Cardinal mark.
The main channel, which has minimum depths of 3m BCD for most of its length, narrows considerably at Salterns buoy, VQ.R, where the direction of the channel changes from North to Northwest. Vessels approach from between East Milton buoy and NW Sinah buoy, leaving Sword Point buoy Fl(3)G.5s to starboard and passing between the lit green buoy Fl.G.3s and South Salterns buoy, Fl(2)R.5s. A bend in the channel is marked on the west side by Salterns buoy, VQ.R.
The north section of Broom Channel lies in an approximate direction 332(T). The channel is marked by lit red and green buoys
