The Boat is the most basic naval unit. Moving a land unit onto a port will turn it into a Boat. The health of a Boat is determined by the unit it carries.

A Boat can be upgraded into a Ship for five stars, and a Ship can be upgraded into a Battleship for 15 stars once Navigation is researched. (The total cost of upgrading a Boat into a Battleship is 20 stars.) Upgrading a naval unit does not heal it.


  • Carry: The Boat can carry another unit inside it. This unit will be released if the Boat moves to a land tile.
  • Dash: The Boat can move and attack in the same turn.
  • Float: The Boat can move on water tiles. If the Navigation technology is unlocked, it can also move on ocean tiles.
