The January 2009 issue of the Journal of Navigation included a paper (John Wilde Crosbie 2009) entitled, “Revisiting the lessons of the early steering and sailing rules for an e-navigation age.” Following a description of the development of the COLREGS from the early 19th century, he concluded that the current steering and sailing rules should be replaced by a single rule more suited to modern conditions. This might take the form of rule stating that a vessel taking action to avoid collision should not pass ahead of the other vessel. Such a rule would require a radical change in the philosophy of collision avoidance at sea, and evidence is required that it would be both effective and acceptable by mariners. Radar simulator experiments, conducted by the author some years ago, in another context, suggest that this might be the case. An analysis of the experimental results and some conclusions are reported in this paper. The author believes that further trials, specifically designed to test the Crosbie proposals, would be desirable.

In accordance with Rule 17a)ii) a stand-on vessel may take action to avoid collision by her manoeuvre alone, as soon as it becomes apparent to her that the vessel required to keep out of her way is not taking appropriate action in compliance with the Steering and Sailing Rules. Such an action to avoid collision must be taken in proper time. An OOW should know the minimum distance for taking avoiding action in every particular case of approaching vessels. The safe distance mainly depends of the relative bearing of an approaching vessel and her speed. In particular own vessel manoeuvrability should be taken into account. The safe minimum distance could be calculated in advance with an Excel calculation sheet. This paper presents a method for preparing a table of safe minimum distances to be used during a Navigational Watch.
