In clear weather, many of us have used the curve of pursuit to avoid a vessel converging from well out on the starboard bow. We have said ‘Starboard’ and followed that order with ‘Head straight at her and report when you have regained course’. Convenient and safe though this technique may be in clear weather it can hardly be recommended for use with radar in fog. Apart from anything else, the other ship may have radar and may also take action as the distance between the two ships decreases. The slowly changing nature of our course would make it well nigh impossible for own ship's radar plotter to determine what action the other ship was taking, and might easily lead to disaster.
