Thistleworth Marine Limited is a residential marina situated on the River Thames at the junction of the River Crane. Formed in 1973, it is a non-trading company which functions as a co-operative, residential association. Moorings, which are pontoon based, are commensurate with a share ownership in the Company proportional to the size of craft.

Located on the upper reaches of the fully tidal Thames, 200 meters downstream of Richmond half-lock, we are in the London Borough of Richmond-upon-Thames and the county of Middlesex, adjacent to the borders of Hounslow and Surrey

We comprise 28 vessels ranging from purpose built houseboats, barge conversions, humber keels and dutchmen, narrowboats, lifeboats and an historic twin engined diesel yacht converted from an Admiralty steam harbour launch! Overlooked on the Middlesex bank by Gordon House we face the upstream end of Isleworth Ait, which is a nature reserve, and enjoy a wide variety of ducks and birds, aquatic life and unusual flora that has migrated from nearby Kew Gardens.
