Ship Customization Items are a way to make personal touches on a player's boat. Most of these categorized placeables have more properties than only being visually impressive. A player can rest in a bed, get light from deck fire pits and have storageable chests and crates stacked anywhere on all boats, besides the Sailing Raft and Small Sailboat.

Some of these customization items are only gained by crafting, others by trading and some by Quests.
