To minimize the amount of time a crossing ship spend crossing the traffic-lanes, there should be a right angle between the lane ...
The oldest sailing directions, dating back to the middle ages, descended directly from the Greek and Roman periplii: in classical times, in the absence of real nautical charts, navigation was carried out using books that described the coast, not necessarily intended for navigation, but more often consisting of reports of previous voyages, or celebrations of the deeds of leaders or rulers.
The English Channel connects the Atlantic Ocean with the Southern part of the North Sea and is one of the busiest shipping areas in the world with ships going in numerous direction: some are passing through in transit from the Southwest to Northeast (or vice versa) and others serving the many ports around the English Channel, including ferries crossing the Channel.

In modern times, computer software can greatly simplify the passage planning process and ensure that nothing important is overlooked. [8] Passage planning software may include functions such as waypoint management, distance calculators, tide and tidal current predictors, celestial navigational calculators, consumables estimators for fuel, oil, water, and stores, and other useful applications.
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed.
