Tschaika were either 48 m (157 ft) (Double Tschaika), 24 m (79 ft) (Ganz ("Full") Tschaika), 12 m (39 ft) (Halb ("Half") Tschaika)^[1] or 6 m (20 ft) (Quarter Tschaika) in length, operated by sail or oars. Between 30 and 50 men were in service, commanded by an officer, with a helmsman, an armourer, a drummer, two bowsmen, and up to 36 oarsmen.^[2]: 11

Chaikas were between 18–20 m (59–66 ft) in length, 3–3.5 m (9.8–11.5 ft) in width, and 3.5–4 m (11–13 ft) in depth.^[3] The bottom of a chaika was carved out of a single tree trunk, with sides built out of wooden planks. To protect the boat from enemy guns or from sinking, reed bales were tied to the gunwales of the boat. One such boat could carry around 50 to 60 men and up to 6 falconets (small cannon). Some chaikas also had two steering oars, so that the boat never needed turning around to switch direction.^[4]

A similar, but larger boat used by the Zaporozhian Cossacks for both transport and warfare was called a baidak.
