I am trying to make up my mind about a furling screacher on the pole versus a spinnaker . I would like to leave it in place virtually all the time but would like to understand more about the likely windage effect. (if I need to drop it when going upwind then it seems a bit pointless) Also what weight of sail cloth to go for, in the hope I can have something very light that might furl tighter and be less clumsy. Are there any Farrier sailors with experience of keeping a furled screacher more or permantly out there who might be able to advise me?
