Zuiderzee NZ43 (ca. 1310)
This small cog was discovered during irrigation work along the western coast of the Zuiderzee in 1971. Aleydis Van de Moortel, who conducted a study of this hull a decade later, has produced a thorough analysis that included three-dimensional research and a complete investigation of the hydrostatic and hydrodynamic properties of hulls of this type.1
