Cawsand Bay is about one mile (1.6 km) across and about a mile and a half (2.4 km) wide across its mouth and is bounded by Penlee Point to the south.
A once-popular ballad entitled "Harry Grady and Miss Elinor Ford, the Rich Heiress" appeared as early as 1840 in Hamilton Moore's Nautical Sketches (William Edward Painter, 1840).[3] It was included under the title "Cawsand Bay" in Sir Arthur Quiller-Couch's The Oxford Book of Ballads (Clarendon Press, 1910).[4]
