Thanks Pascal, but it might have been gone something wrong in my phrasing of my question. Your information is in relation to handicaps. In my question I mean single-handed as sailing alone and not as sailing with a single hand. What i am trying to find out is a good size jib for a Edel IV. A sail easier to handle when tacking. I thought to look at the used sails here in the online sites.
Best regards
