Boat hull construction templates including longitudinal profile and transverse ribs. I’ve included 20 individual rib sections, all numbered to keep things simple during assembly. The file features a nested layout ready for CNC or laser cutting, plus the raw side elevations & profile views. Everything is in metric (mm) & suits plywood, aluminum, or steel builds. Covers the main frame profiles, stations 1 to 20, and the rest. Just a clean set of 2D vectors for a custom marine project. Compatible with CAD 2018 versions and up.
