A sail furler with a recirculating halyard includes a foil having a longitudinal halyard channel and a longitudinal recirculating halyard channel formed within; and a halyard, having a first and second end, the halyard affixed at its first end to a slider, the slider affixed to head of the sail, the halyard rising to an upper end of the foil, leading through a top cap, and then descending downwards through the halyard channel to an exit of the halyard channel in proximity to a lower end of the foil, then ascending through the recirculating halyard channel, and terminating at its second end to the slider, so that the distance between the second halyard end and the head of the sail remains constant whether the sail is raised or lowered.
