Navigating to Haslar Marina by sea
Haslar marina is situated on a peninsula on the western side of Portsmouth Harbour, opposite the city of Portsmouth. The Marina is located immediately within the entrance on the western side and is directly accessible from the harbour's boat channel.
The Harbour is a busy commercial, naval and leisure port so care should be taken in and around the entrance. Please consult up-to-date charts and pilot books to ensure you are aware of any navigational dangers. Visitors should also be aware of the King’s Harbour Master Rules and Regulations and current Notices to Mariners, the weather and tides. See Gosport Marina tide times here.
Vessels over 20 metres must contact the King’s Harbour Master on VHF Channel 11 before entering or leaving the harbour.
Small Boat Channel
All vessels under 20m must enter and leave the harbour through the Small Boat Channel on the western side of the harbour entrance. When approaching from the west, boats should approach the harbour through the Swashway (also used by ferries and commercial vessels). This runs 49 degrees (true north) on the right-hand edge of the prominent block of flats in transit with the War Memorial.
Approaching from the east
hen approaching from the east, beware of the submarine barriers which run due south from Southsea sea front to Horse San Fort and are a hazard to all craft. There are two passages through the barrier – the inner passage approximately 200m off the beach (marked by green and red piles) and the outer passage approximately 0.8nm off the beach (marked by a quick flashing red dolphin and a green pile).
