Maascenter is an important navigation point for ships entering the Port of Rotterdam.
In principle Maascenter is a buoy before the coast of Rotterdam, Netherlands.
[1] Maascenter buoy is also the pilot station where ships entering the port get their pilot on board(except for ships with a draft > 14 meters as they get their pilot on board before entering the Eurogeul.
For these ships Maascemter is also important as they will meet their tugboats at this point.).
[1] Ships with destination Rotterdam (that require a pilot) need to contact the traffic-centre 24 hours before expected arrival (ETA) at Maascenter[1] This article related to ports, harbors or marinas is a stub.
