Erwankerauzen, Are there any particular numbers that you are considering other than weight. Beam width? SailArea? Mast height? I think 140kg would be achieveable with no jib for a home builder even when building from ply. However I think the jib is an assett that would be sadly missed when doing distance races or courses other than windward leeward. Regards, Phill
I know that the voices in my head aint real, but they have some pretty good ideas. There is no such thing as a quick fix and I've never had free lunch!
