If you like the idea of electric assist but do not want extra weight sitting on the board or mast top plate, this is the part that makes the Duotone system feel so clean on the water.\u003c\/p\u003e\n\u003cp\u003eInstead of putting battery weight onto the board, Duotone moves it onto your hips in a waterproof battery box attached to a purpose-built harness.
