Conspicuous grey shading or blue colours are traditionally used in printed nautical charts to display shallow water.The problem is that what is "deep" water for one size of ships might not be so for another size.To understand the extent of navigable water the bridge crew has to make a number of relatively complicated mental calculations.This paper suggests an automatic way of displaying NoGo areas that will give the bridge officer an at a glance knowledge of his ship's manoeuvrable space, present, and along the future route.A prototype has been developed and was tested in the EU project ACCSEAS with professional mariners.The system was rated as good and acceptable from a professional point of view although there is still improvements to be made.
