Falmouth Harbour, including the Carrick Roads, is reputed to be the third largest natural harbour in the world. Falmouth Harbour Commissioners are a statutory port authority with responsibility for the Inner Harbour at Falmouth (excluding Falmouth Docks), the Penryn River up as far as Boyers Cellars, the southern part of the Carrick Roads and a large part of Falmouth Bay. As well as providing regulation of its Harbour Area the Commissioners provide small craft facilities for residents and visitors.
