Pilots, equipped with a 24-channel VHF set communicate with the appropiate radarstation, use the assigned channel for the radarcoverage area concerned and switch to the next channel after hand-over has taken place. The information supplied to pilots consists of the position of the ship, relative to familiar landmarks and leading lines, amplified with additional information, such as sur- face pictures, shipping movements in the area, possible navigational hazards etc. Most of this information is extracted directly from the (shore) radarscreens Rivercraft, which are not under ob- ligation to be piloted, usually monitor these channels to acquire information on traffic on the river, needed for a safer passage. The present systems has proved to be a invaluable aid to the safety of navigation. It has reduced the number of accidents and collisions spect- acularly under conditions of reduced visibility. The available statistics show that in the period 1959-1963 an average of 0,28 collisions per 1000 shipping movements took place, compared to for example 0,83 on the river Scheldt and 0,68 on the river Thames.
