Picture this: your desk, a tiny galleon riding laser-cut wooden waves, rigging stretched taut between masts. This isn't another generic ship puzzle—it's a desktop replica of the vessels that dominated Atlantic trade routes for 150 years during the Age of Exploration.
The galleon's design revolution? A lower forecastle and elongated hull that made ships faster and more stable than the carracks they replaced. You'll recreate that engineering in miniature: snap-fit plywood pieces form the hull, thread creates authentic standing rigging (the fixed lines that supported masts), and a sculpted wave base turns it into a conversation-starting display.
No glue. No paint required. Just 2-3 hours of focused assembly.
