Approach to Rotterdam, Nederland (1911)
After the Scilly Islands and the different Capes situated on the southern coast of England have been sighted, Boulogne-sur-Mer comes into view. This port has a population of 50,000 inhabitants and is situated at the mouth of the Liane on the northern coast of France, between the Capes of Gris Nez and Alprech. The harbor of Boulogne is divided into two distinct parts; the outer deep-water harbor and the inner harbor (the latter being subdivided into six different divisions).
A dyke of 6,984 feet in length, the so-called “Digue Carnot”, forms the outer deep-water harbor. This dyke, a magnificent structure, extends at a right angle with the coast, south of the city, for a length of 4,128 feet, making a curve of 1,170 feet and continuing north for 1,677 feet; thus protecting vessels fully from any gales. The water in this outer harbor has a depth of from 35 to 50 feet according to tide, permitting the anchorage of the largest transatlantic liners at any hour.
From Boulogne-sur-Mer the Cape of Gris Nez, a familiar landmark because of its powerful revolving light, is reached in less than one hour. Proceeding further north, another point of interest is passed, namely the Goodwin Sands, well known because of the great number of sailing vessels that have been wrecked off this point.
After Dover has been passed, no land is sighted until the Hook of Holland is reached. The steamers then enter the Waterway and, sailing up the River Maas, reach Rotterdam in about two hours. The scenery along the borders of this river is very typical, with small old towns and villages in the distance. As Rotterdam is neared, a beautiful view of its port presents itself, the bustle and traffic on the quays rendering the scene exceedingly interesting.
