The Tchektirme was the typical Turkish workboat, a Mediterranean variant of the flat-bottom coasters rigged with a fore-and-aft rig. This type of ship, linked to the Greek Skapho (a small fishing boat), and the large Sakouleiva, was long-derived from the Byzantine Khelandion (chaland). The French Trecandin was also related to these ships, but with a somewhat different rigging.
