Unfortunately I don't have a good mechanism setup for localization yet. The diplomatic dialog could be localized pretty easily, but not the UI.
No, there's no victory condition yet.
Currently only the Humittes have boats. Build a Trade Port and have an army interact with it (either through the Interact action, or just right click). The army will then embark on the boats, and can sail around on the sea. They can disembark from the boats, and leave them behind.
