The reason that there are few pictures from the Maasvlakte is,there are few large ships.
The weather lately was not so good, much wind.You can not hide on the Maasvlakte.
If there are few large Container vesels or tankers comming,the spotters are all in the Beerkanaal.For the Maasvlakte,you need to drive about 25 km further. For Container ships the beerkanaal in the morning is the best place.And for Tankers the Calland kanaal.Thats the reason
