 If the sail meets these conditions, then it may be suitable for use with a roller furling system; if the sail is not, then it may be possible to replace the sail with one of a design more conducive to furling.Jibs and genoas, for example, are generally suitable for furling, as they are relatively flat, while a gennaker, with its larger degree of camber, is probably not suitable for furling.In particularly windy areas, sometimes a separate smaller jib may be separately rigged as a Solent to avoid the disadvantage of a partially furled Genoa.
