The name comes from IJ and geul, a Dutch word meaning "the portion of a channel that often has to be dredged."
Traffic is strictly regulated; vessels must follow the leading lights over the last 23 km, which are formed by the Hoge vuurtoren van IJmuiden and the Lage vuurtoren van IJmuiden.
18 km from the coast, a space was created so that in case of problems, it is possible for vessels to turn back.
The Prostar Sailing Directions from 2006 provides detailed approach and restriction information.
