Study of a dogger from before the port beam. Her gaff mainsail is set and her lateen mizzen, staysail and square topsail are brailed up. The ship carries a square-rigged spritsail under the bowsprit. In the Dutch language this sail is known as a “blind” (blinde) because it effectively blocks forward vision when set. A very similar drawing is preserved in the collection of the National Maritime Museum, Greenwich (inv.no. PAF6634). Robinson dates the NMM drawing around 1685.
