The First opportunity for this will be after defeating the Bear in the Siberian Wilderness. You will progress through an ice cavern and Lara will remark on a Byzantine ship. These are optional and not on the direct path forward so you will need to go out of your way to reach this. The first is not real hard, simply solve the puzzle and get to the top, you will need to break ice using the ships parts to climb up. At the top there is a treasure book at the helm which will also reward you with a skill perk, this one is rapid fire arrows. Reading the book will complete the challenge tomb and unlock this achievement.
