Andreas Lous

Later in 1756 he was given some responsibility for dock workings but was soon back at sea in Danish waters in Sejeren and again to the West Indies in Møen.

In various ships —Wenden, Jylland and Saltholm- serving largely in Øresund in the 1760s he began the survey and measurement of the Sound from Helsingør to Dragør and then further south around the island of Møen.

Further improvements in the quality and quantity of charts and pilotage instructions would be made some twenty years later by Poul de Løvenørn.

In addition to his pilotage and seagoing duties Andreas Lous had responsibilities for docks (1756) and worked for the Danish Customs Service (1776).

One of the four ships-of-the-line that he commanded was Printz Friderich,[6][Note 4] which ran aground and was lost on Kobbergrund in the Kattegat in September 1780.
