Portsmouth Lifeboat Station is located at Eastney Point near Southsea, on Portsea Island, in the English county of Hampshire.

The location was considered to be an ideal position "whence a Life-boat can proceed, either under sail or in tow of the Admiralty or other steam-tugs, to shipwrecks along that coast and round the eastern approaches to Spithead.

In 1964, in response to an increasing amount of water-based leisure activity, the RNLI placed 25 small fast Inshore lifeboats around the country.

The first Inshore lifeboat (D-48) was paid for by funds raised by Hemel Hempstead Round Table.

By 1967 the station was also operating a rigid hull inshore lifeboat, with the craft being kept at permanent anchor in the harbour at Eastney.

Arriving on scene 13 minutes later at 03:59, they found a man and boy, lashed both together, and to their boat, the motor cruiser Valon.
