Description : Nouka Baich (Bengali নৌকা বাইচ) is the traditional, dragon boat-style folk rowing sport of Bangladesh, deeply embedded in the country's riverine culture. Held annually during the wet and autumn monsoon months when rivers and haors swell with water. Long, narrow wooden boats (ranging from kosha, goyna, to sarangi boats depending on the region) are manned by teams of 7 to 100 rowers (majhis). Motor engines are strictly prohibited. Competitors and spectators sing traditional Sari gan folk songs (such as Ronger Nao Ronger Boitha) to maintain a synchronized rhythm during the intense races. Bangladesh.
