HNLMS Schorpioen is a Schorpioen-class monitor built in France for the Royal Netherlands Navy in the 1860s. These new ships were equipped with heavy rifled 23 cm guns, and a heavy armor. The hull had an armor plated belt of 15 cm and the gun turret, housing the two guns, had almost 30 cm of armor.
She came from the building yard with two tripod masts and able to employ about 600 m2 of sails, but she proved to be a difficult sailing ship and some years later the yards, masts and the sails were removed. As with Buffel her huge steam engines gave her a maximum speed of 13 knots. Her striking weapon was the pointed ram bow, slightly different from Buffel's, but she never ever used this overestimated weapon.
