Sewn boat

A sewn boat is a type of wooden boat which has its planks sewn, stitched, tied, or bound together with natural fibre rope (e.g. coir in the Indian Ocean) tendons or flexible wood, such as roots and willow branches. Sewn boat construction techniques were used in many parts of the world prior to the development of metal fasteners, and continued to be used long after that time for small boats to reduce construction costs where metal fasteners were too expensive.
