Coracles are small, round boats. Generally formed like baskets, woven tightly or covered with hide or fabric, and sealed with bitumen or paint. 

They are working boats that were re-invented across the globe. Native Americans in the Great Plains built coracles of thin branches, and wrapped them in buffalo hides. Coracle culture thrived in the British Isles, where regional variations of the coracle arose to suit different needs and available materials.The wide form of the coracle displaces much water, and can transport considerable weight. They were used for quick and convenient river crossings, for fishing, and also for poaching by the light of the moon on lands reserved for royalty. 

Today, wide, open-formed coracles are frequently used as sea-faring fishing boats in South Asia.
