A line management system for an outrigger structure is provided for guiding outrigger cords through cord passages to maintain an independent longitudinal displacement in order to prevent entanglement. The system includes a plurality of outrigger cords, cord management units, and retention devices. The plurality of cord management units are coupled to the outrigger structure and are longitudinally spaced one from the other along the outrigger structure. Each of the cord management units defines a plurality of transversely offset cord passages respectively guiding predetermined ones of outrigger cords to maintain an independent longitudinal displacement relative to the outrigger structure.
