The following types of ships are to distinguish: a yacht, a small boyer, a man-of-war (fregate) and a three-deck Admiral’s ship (a fregate of c. 60 guns) with banner in the mainmast. Only nine men-o-war of this last type have been built for the Dutch Admiralty during the entire seventeenth century.
Pieter Coopse is considered pupil of Ludolf Backhuysen. Due to his premature death the artist has left but a small oeuvre. The master of Hoorn is merely known for his drawings and pen paintings, oils by his hand are particularly scarce and can all be dated in Coopse’s late years.
