The Varne Bank is a five and three quarter mile long sand bank in the Strait of Dover, lying 9 miles (14 km) southwest of Dover in Kent, England. With the Lobourg Channel running along it, the Varne bank lies immediately south-west of the deepest point 223 feet (68 m) in the strait of Dover. Its rectilinear shape is similar to other banks in the strait such as South Falls bank bordering the Lobourg Channel on the east, the Colbart bank (a.k.a. the Ridge) and others. Rectilinear-shaped banks are only present on the English side of the strait.
Lying almost in the middle of the south/west international traffic English-side channel of the English Channel, the Varne Bank is a constant concern for both British coastguards and shipping. The sea above it presents strong rippling, especially when strong tides occur, and is noted for its extra roughness during bad weather.
With a minimum depth of about 10 feet (3 m), it is marked by lighted buoys to the West, East and South. Due to its heightened risk, there is still a Trinity House automatic lightvessel placed near the Varne Bank.
Ships that founder on the Varne Bank are often stated as being lost on the Goodwin Sands in error, perhaps because the Varne Bank is less well known than its close northerly neighbour. Due to the volume increase in shipping through the world's busiest channel, several proposals have been made to eliminate the Varne Bank through dredging. However, also due to its shallow depth, the Varne Bank is a productive location for fishing, especially for cod and scallops.
In 1802, mining engineer Albert Mathieu made proposals to Napoleon for turning the Varne Bank into an island staging point for the Channel Tunnel. In the 20th century, a proposal was made for a Channel bridge, which would have used the Varne Bank as a staging post for a support structure.
