The objective of this paper is to recover and highlite the constructive processes and the assembling of Chiloean wooden sea crafts, through the establishment of relationships between the design and digital specification for manufacturing of double curve roof, and traditional construction techniques of boats. The research is based on the exploration of digital constructive techniques, which integrate the design and the manufacturing systems of double curvature surfaces. By means of the reinterpretation of the constructive processes and the structural system of the Chiloean sea crafts.
