Ascreacher[1][2] is asail that combines the features of aspinnaker and a reacher.
Its similarity with a spinnaker is that it is not attached to astay along itsluff, and typically has a slightly larger curvature than agenoa. Luff shape and tension is maintained by thehalyard and abolt rope which is woven into the sail itself, and it is this stiff tensioned rope which allows the sail to be furled on itself. In addition, many screachers aregybed by allowing the sail to fly free and pass in front of the bolt rope and invert, much in the same way that an asymmetrical spinnaker is gybed. Tacking with a screacher may require furling and re-setting. The similarity with a genoa is that it is typically a white sail, and theclews always overlap the mast.
