The Ma Ikkada was a very thin and crudely-constructed wooden raft, made out of barrel lumber with two rowing paddles.
The Ma Ikkada was created for the Donut Race. Sanji provided power for the raft by rowing at the beginning, then Luffy used his Devil Fruit ability to become a propeller, greatly increasing their speed, until Luffy grew weak from submerging part of his arms into the sea for too long. The raft was destroyed while escaping the Long Ring.
