Set sail for the high seas in your Boat and when it returns you will be rewarded.
After creating Equipment on the Dock, load up your boat with the Equipment and set sail. Once your boat returns from the high seas you will be rewarded with Ingredients and Crates.
The Ingredients (Salmon, Avocado, Saffron, Shrimp, Lobster, Coconut, Pineapple, & Caviar) you will be rewarded with and the amount you receive will depend on the type and amount of Equipment you load your boat with. Crate rewards will vary depending on the length of time you are sailing. You will need to claim all your rewards from the Boat before you will be able to set sail again.
