Pirat dinghy flat pattern

Pirat is an old German dinghy design with the aim of simple construction and forgiving handling for beginners. Its overall length is 5 m, sail area is 10 sqm. This model is the flat pattern of the boat for plywood stitch and glue construction (which was not available at the time of design, but would align with the design intent). Only a scaled down paper model was built yet, but it seems to work. For the 3D design, I used the drawings available at holzpirat.org: https://www.holzpirat.org/wp-content/uploads/2015/02/Bauplan-Pirat-SUI-534-Spant-01234.pdf https://www.holzpirat.org/wp-content/uploads/2015/02/Bauplan-Pirat-SUI-534-Spant-5678.pdf https://www.holzpirat.org/wp-content/uploads/2015/02/Bauplan-Pirat-SUI-534-Spant-91011.pdf
