Teasel Transom

In 1982 the BBC filmed Arthur Ransom's Coot Club and The Big Six; they needed an authentic Norfolk Broads yacht and boatyard. The boatyard was Hunter's Yard at Ludham and the sloop-rigged, carvel-built mahogany yacht, the Lullaby (built in 1932) became the Teasel for the three months of the filming.
