The Varne (50° 58' N, 1° 20' E) is a dangerous narrow shoal running 8 miles NE-SW, which is marked at its NE extremity by Varne Light-vessel, on its SE side by E Varne Light-buoy (port hand), on its NW side by Mid Varne Light-buoy (starboard hand) and at its SW extremity by S Varne Light-buoy (S cardinal). The shoal is steep-to, with strong tide rips in its vicinity, and, in bad weather, a heavy sea breaks over it. The shoal should not be crossed but may be passed on either side. The SW deep draught route (2.68) passes SE of The Varne, between the shoal and The Ridge (50° 53' N, l° 20' E), which is marked at its N extremity by N Colbart Light-buoy (N cardinal).
