The Soldier Dock system is a special system built within the ship represented externally by the two giant plates marked with giant numbers on either side of the ship. It is a turn table of compartments of sorts that each contain a special device or vehicle that the Straw Hats can use. It is named like this because the vehicles stored within are (which are commonly released from the left-side plate), as Franky calls them, the soldiers of the Thousand Sunny.

   Channel Zero: Two compartments containing the paddle wheels to change the ship into Paddle-Wheel Sunny. It is powered by Cola. The wheels can rotate in reverse and are not connected to one another. With these wheels, the Thousand Sunny's heading can be changed easily. This was first seen being used in the manga when Franky showed use of it in order to pass a raging storm.[7] In the anime, it was first seen being used to escape from an illusion of a fleet of Marine ships.[8]
