This paper proposes a design methodology for the manufacture of complex, double-curved surfaces based on the digital reconstruction of traditional structural and constructive elements of Chiloean boats. It also suggests a beneficial association between digital design and CAD CAM for manufacture using locally crafted construction techniques. The incorporation of innovated contemporary digital design and fabrication tools into traditional construction systems, aims to optimize and perpetuate traditional artisanal craft construction of complex shapes developed in the south of Chile. The importance of this research in budget-restricted economies, lies in the possibility of applying local construction and assembly techniques to new sophisticated designs that may satisfy the country's architectural needs. Scale models are used to record the design process and constructive development while information flow charts document the design methodology for the construction of complex geometries.
