You need Dredge refined metal in order to upgrade your hull to tier 2, so you might wonder where to get this particular resource. It's a curved metal sheet that the Shipwright can use to upgrade various aspects of your fishing vessel, so you can take a few more hits or crash into a few more cliffs before your ship is completely destroyed.
Dredge tasks you with taking to the ocean and living your best fishing life by exploring a cluster of islands and getting to know the locals. It's not all plain sailing, though, as the sea hides some less-than-friendly creatures, and if you misjudge a turn while docking your boat, you risk damaging it beyond repair. It really does pay to upgrade as soon as possible, so here's where to get refined metal in Dredge to upgrade your hull.
