A sewn boat is a type of wooden boat which is clinker built with its planks sewn, stitched, tied, or bound together with 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.

Stitch and glue is a simple boat building method which uses plywood panels temporarily stitched together, typically with wire or zip-ties, and glued together permanently with epoxy resin. This type of construction can eliminate much of the need for frames or ribs. Plywood panels are cut to shape and stitched together to form an accurate hull shape without the need for forms or special tools. This technique is also called "tack and tape", or "stitch and tape". Seams are reinforced with fiberglass tape and thickened epoxy.
