The Medina-class gunboat was a class of 12 Royal Navy Rendel (or "flat-iron") gunboats mounting three 6.3-inch guns, built between 1876 and 1877.^[1] Flat-iron gunboats were normally built without masts or rigging, but the Medinas carried a full barquentine rig. Their robust iron hulls meant that they lingered on as diving tenders, barges and lighters, with five of them working into the 1920s. The hull of Medway lies in shallow water in Bermuda and is visible on satellite imagery.
