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!
