Somerleyton Marina sits on the River Waveney between St Olaves and Oulton Broad in the Norfolk and Suffolk Broads. Owned by the Somerleyton Estate, it comprises a mooring basin and a long-established boatyard, and serves primarily as a boat storage facility.

Its relatively remote position away from the Broads' busier destinations means it sees less pleasure-craft traffic than many other moorings in the area.

Plans have been submitted to the Broads Authority to revamp the site, including upgrading existing pontoons and the parking area, and adding 15 residential moorings on the western side of the basin.

The estate considers the marina's quiet surroundings well suited to that use.
