Port Solent Marina

A locked marina deep inside Portsmouth Harbour, pairing sheltered berthing with a large waterside leisure development.

Marina · The Solent

Welcome to Port Solent Marina

Port Solent is a destination reached in stages: harbour entrance, inner waters and finally the lock. The reward is a protected basin with an unusually extensive shore life around it.

Marina Arrival VHFChannel 80
Lock InformationControlled lock operated 24 hours. Published approximate lock waypoint: 50°50′37″N, 01°06′W; use for general orientation only.

Setting & Character

The marina is enclosed and urban, surrounded by waterside development rather than open Solent horizons. Its atmosphere is self-contained once the lock gates are behind you.

Arrival by Sea

The journey begins with current Portsmouth Harbour directions and continues through the inner harbour. Call Port Solent on VHF Channel 80 for lock instructions and treat the published waypoint as orientation, never pilotage.

Berthing Experience

Berth count and dimensional limits are not stated in the supplied record. The lock runs 24 hours, yet every boat still needs confirmed suitability and an allocated berth.

Facilities Afloat

Reception and lock operation are published around the clock. Remaining berth services must be confirmed directly rather than assumed from the marinas large shoreside development.

Marine Services

No lifting or storage capability is claimed from the current dataset. Arrange any technical work using vessel-specific information from the marina.

Ashore

The developed waterfront gives crews a broad choice of leisure activity without travelling far. It feels very different from a village or rural river marina.

Best For

Sheltered stays, crews who appreciate an active waterside development and skippers comfortable with a controlled lock arrival.

Less Suitable For

A quick open-water stop or an unplanned arrival made without harbour and lock preparation.

History & Local Character

Port Solent represents a modern chapter of Portsmouth Harbour, converting enclosed waterside land into a marina and leisure destination far from the historic entrance.

Nearby Cruising

The harbour contains Gosport, Haslar and Portsmouths naval landscape; beyond it, the eastern Solent leads towards Cowes and the Isle of Wight.

Skipper's Notes

Do not confuse 24-hour operation with unrestricted entry. Obtain current lock directions and keep the boat prepared for confined manoeuvring.

Old Sea Dogs View

Port Solent is the long way in and the easy place to stay. The lock gives the arrival a satisfying full stop.
