Sea lane
A sea lane, sea road or shipping lane is a regularly used route for vessels on oceans and large lakes. In the Age of Sail they were not only determined by the distribution of land masses but also the prevailing winds, whose discovery was crucial for the success of long voyages. Sea lanes are very important for trade by sea.
