A series of navigability tests undertaken in a canal, at normal transit speeds, showed that cross-section factors of n = 4 to 4.5 were inadequate, but piloting was relatively easy with n = 4.5 to 5. The concepts of stopping distance and of a minimum interval are valid for any ship canal, or other shipping channel where traffic is likely to approach saturation at peak periods. Determination of stopping distances is also necessary with respect to harbour approach manoeuvres of large ships. The example of the canal shows that the stopping distance has to be defined as a function of the manoeuvring space available to the ship on either side, i.e., the width factor. It is in fact necessary in this case to define not just the stopping distance, but the stopping area, characterised by its length, its width and even the shape, full consideration being given to all the limitation imposed by the overall layout of the actual harbour.
