LANBY

LANBY, a contraction of Large Automatic Navigation BuoY, was a type of floating navigational aid designed to replace lightships.[1] Now obsolete,[2] they were originally made in the USA by General Dynamics and adapted by Hawker Siddeley Dynamics for use in British waters in the early 1970s.[3] They consisted of a circular hull with a raised central structure containing a 360° light and foghorn, and sometimes also a radio beacon. They were monitored from onshore and designed to run for extended periods without repair. Their running costs were estimated to be as low as 10% of those of lightships.[3]
