The Ocean is the core area of the game, and is the place the player will spend most of their time. Throughout the game, the Ocean is the main source of Materials, as it will continuously spawn Flotsam as long as the raft keeps moving. The main enemies of the Ocean are Sharks and Seagulls, though the Seagull is a bigger threat to the player's Food Supply as it attacks Crop Plots.
Despite the Ocean seeming infinitely vast, it spawns around the raft as it sails. In the same way, Islands are spawned in the cardinal direction the player is sailing in a specific radius to the raft. Lastly, the ocean floor technically exists, although it is completely barren and holds no Materials.
