So now that your sail is reefed, what do you do with the lowered panels of the sail that are no longer set? On Nikki, I use dedicated buntlines: small-diameter lengths of line that pass through a horizontal series of cringles in the sail, between the reefed tack and the reefed clew, and tied with reef knots. Their only purpose is to store the "bunt" — that excess sailcloth that hangs down from the finished reef — to increase visibility from the helm and reduce flopping. For mainsails without buntlines, the sail can be gathered and secured with sail ties rove through the appropriate reef points, or through cringles in the sail, which serve the same purpose. Either way, buntlines or sail ties should never be pulled tight before tying, because they will strain and eventually tear the sail at the cringles. Your reefed sail should be left loose-footed, although the buntlines or ties can be knotted under the boom or only around the bunt itself, which I prefer. When I race Nikki, I leave the bunt untied because it doesn't get in the way and it reduces the time to take another reef in or shake it out.
