Re: "Class jib", "working jib"
You are dealing with a wide range of different definitions here. A 100% jib fills the entire foretriangle. It may or may not be the "class jib". The class decides what the "class jib" is. It may be a 90% jib, filling 90% of the foretriangle, or it may be a 110% jib, more than filling the foretriangle. A class could have a 125% "class jib". It depends on the class. A "working jib" is another thing entirely. It would be the smallest jib that is used regularly. It would probably be a 100% jib or less; it depends on the boat and what the skipper considers his standard-use sail. Essentially, you have brought up three different ways to descriibe headsails: percentage of foretriangle, class rules, and working sails. They all overlap, so it is confusing. Seaparate them in your mind, and it should become clearer.
