Admiralty charts 1794 and 2529.  All vessels not in possession of current charts or navigational publications should make arrangements for a pilot to board on arrival.

The Port Authority as the Local Lighthouse Authority provides a network of navigation marks to assist vessels in navigating within the confines of the Harbour.  Several shoal patches are marked with unlit framework towers, or unlit beacons.  The entrance to Stornoway Harbour is dominated by Arnish Point Lighthouse.  Approach to the outer limits of Stornoway Harbour should be made within the White sector of Arnish Point Light (bn.122° and 193°).

Vessels should approach the Harbour from the south, keeping within the White sector of Battery Point Light (58° 12.2 N and 006° 22.1 W), and maintaining a distance of 2 cables east of Arnish Point, thereafter leaving the Reef Rock red buoy to port.  Vessels should then take up a westerly  heading across the Harbour, keeping within the White sector of Creed Point Light (58° 12.03N and 006° 23.48 W).  When Goat Island is abeam to starboard, and the White sector of the No. 1 Pier light is open, vessels should adopt a northerly heading, actual course dependent on which berth has been allocated. 

Vessels planning to use the facilities at Arnish Pier should make use of the Glumaig sector light (58° 11.3N and 006° 22.75W) for best line of approach to the berth.

There is a 27 berth marina located in the northern part of the Harbour, with limited water depth at chart datum.  All vessels should contact the Harbour Office prior to taking up a pontoon berth, as some berths are allocated to local users.
