Carvel (boat building)
（重定向自Carvel built）
Carvel built or carvel planking is a method of boat building where hull planks are fastened edge to edge, gaining support from the frame and forming a smooth surface.
In contrast with clinker built hulls, where planked edges overlap, carvel construction gives a stronger hull, capable of taking a variety of full-rigged sail plans, albeit one of greater weight. In addition, it enables greater length and breadth of hull and superior sail rigs because of its strong framing, and is one of the critical developments that led to the preeminence of Western European seapower during the Age of Sail and beyond.
