This method of conducting controlled turns is straight forward and easy to use. The planning is simple and results in turns being defined by their radius and a reference point’s distance from the turn centre. These two values allow for a quick and simple radar set up to provide continuous realtime monitoring from a single source.

Similar to the role of parallel indexing in passage planning, the safe navigation of vessels in confined waters would be enhanced if this technique was widely understood and radar designs allowed for its simple application.
