The metalworking needed to build a clipper in antiquity

In the proposed transition from triremes to clippers, woodworking skill is only part of the problem. A fine clipper hull would require iron components and joints that local producers would need to learn to manufacture. Existing ironworking and the bronze production used for large rams provide a starting point, along with some established production processes. Developing those capabilities could become a lifetime's work, with consequences for both warfare and ordinary transport across the Mediterranean.
