It was typical of many small civilian craft that performed naval duties in the blockade. A sidewheel steamer equipped with the typical walking beam machinery, it was rebuilt to carry three guns. A line of iron plates along the gun wales added a measure of armoured protection. After the war it was returned to lightship service.
