Ahoy there me hearties! I have been on test solid since the ship customization hit. Here is my basic guide to ship customization. First the basics: Ship materials are obtained from ships sunk at sea. Any Warship can drop a materials chest. Bounty-hunters drop a regular materials chest, and Warships drop Rare materials chests. One chest dropped per ship sunk. Open fire and take cover require iron, canvas and gold at rank 1. Full sail requires canvas and gold. Rank 2 open fire, and take cover require silk and steel, and gold. Rank 2 Full sail require silk and canvas.
