# Find Vessels

Depending on your access permissions the list of Vessels might not be visible.

Open the **Vessels** module in the Master Data section.

There are several [sorting and filtering](/release-6.18/voyage-management-system/step-by-step-guides/sorting-and-filtering-lists.md) options available for you to narrow down what you include in the list view, including a "My Vessels" filter that shows all the vessels of which the logged in user is the operator.
