Bamboo Mat

The Bamboo Mat is a non-collideable Ship-decorative object which is currently only obtainable by crafting.

Once crafted, the Bamboo Mat can be placed anywhere on your boat. When "equipped" (right-click the icon in your inventory), hover your mouse on any surface of your boat to preview the placement.

Like most ship-decorations, the Bamboo Mat can be rotated using E (default key) while selected.
