Black Boats are a Naval Unit, developed by Black Hole to transport troops as well as supply and repair units. Each Black Boat is able to repair 1 HP of a unit each turn, draining 10% of the unit cost from the player, regardless of the unit; naturally if the player does not have the funds, he is unable to repair. They are also much like APCs as they are both non-combat units, they both supply units and are able to transport Infantry and Mech units. As opposed to the APC, Black Boats can transport 2 units instead of one, but do not supply adjacent units at the start of each turn.
