I was very interested in the recent correspondence regarding a direction indicator to be fitted to ships and while I note the experiments now being carried out by our Dutch friends there are several points which must be borne in mind.

In the first place, whilst sophisticated arrangements like illuminated arrows may be very satisfactory from the operational point of view, this sort of apparatus is just one more piece of expensive equipment that the shipowner must provide and I foresee reluctance on his part if it is intended that this should come into general use.
