Years: 0750 ~ 0800
The ships of the Númenóreans became ever larger and of greater draught in those days, until they could make far voyages, carrying many men and great cargoes; and Aldarion was often long gone from Númenor. Tar-Meneldur ever opposed his son, and he set a curb on the felling of trees in Númenor for the building of vessels; and it came therefore into Aldarion's mind that he would find timber in Middle-earth, and seek there for a haven for the repair of his ships. In his voyages down the coasts he looked with wonder on the great forests; and at the mouth of the river that the Númenóreans called Gwathir, River of Shadow, he established Vinyalondë, the New Haven.1
