Harbour Guide · The Solent · Portsmouth Harbour

Overview

Portsmouth Harbour is one of Britain's busiest and most historic natural harbours, combining a major Royal Navy base, international ferry terminal, commercial port and several leading leisure marinas within a relatively compact area.

The harbour is shared by naval vessels, ferries, commercial shipping, fishing boats and thousands of recreational craft each year. Visitors should expect a highly regulated environment where careful navigation and adherence to harbour procedures are essential.

Arrival by Sea

Approaching from the Eastern Solent, Portsmouth Harbour is entered through a narrow buoyed entrance between Fort Blockhouse and Southsea Castle.

Maintain a listening watch on VHF Channel 11.

Commercial, ferry and naval traffic may have priority.

Small Boat Channel

The Small Boat Channel provides recreational craft with a safer route clear of the main commercial fairway.

Vessels fitted with engines should use them while navigating the Small Boat Channel.

Craft crossing the main channel towards Gunwharf Quays or Town Camber must obtain permission from Portsmouth VTS on VHF Channel 11.

Old Sea Dogs View

Portsmouth has never been an ordinary harbour. Few places in Britain combine so much history with so much modern maritime activity. Warships, ferries, racing yachts and cruising boats all share the same water, demanding patience, awareness and good seamanship.

The reward is immense. Within minutes of securing alongside, visitors can walk from the decks of HMS Victory to the cafs of Gunwharf Quays before watching another destroyer slip quietly to sea.

Treat Portsmouth with respect, keep one ear on Channel 11 and enjoy one of Britain's greatest working harbours.
