Given that this print is 55 years old the identity of this vessel is a mystery. It does not appear to be either the famous Vasa or the Mars so it is perhaps a creation based on a written description from an earlier text. The word Kravel (or carvel in English) refers to a type of construction 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 pre-eminence of Western European sea power during the Age of Sail and beyond.
