The Amsterdam ships Omlandia and Hoop

Up until June 1652, Boetius Schaeff had commanded the Gewapende Ruyter (36 guns), a Portuguese prize. The Gewapended Ruyter was sunk by the English in June 1652, while returning home from Brazil. Carl Stapel has found that in September 1652, that Boetius Schaeff was in command of the Amsterdam ship Omlandia, which in September 1652 carried 28 guns and had a crew of 85 men. After the Three Days Battle, Boetius Schaeff was appointed to command the ship Hoop (28 guns). In the Battle of the Gabbard (or, the Two Days Battle, or Battle of Nieuwpoort), Boetius Schaeff and his lieutenant were killed and his crew mutinied. In his place, Dirck Pater was appointed to command the Hoop. When Boetius Schaeff was appointed to command the Hoop, his father Maarten Schaeff had been appointed to command the Omlandia. At this stage, the Omlandia carried up to 32 guns. The Omlandia was sunk at the Battle of Scheveningen, although Maarten Schaeff seems to have survived the battle. Sources:
