This is becoming quite tedious-
I looked up the definition of broad seeming as anyone could.

"Broad seeming is when you build curvature into the sail surface, you do this by building the sail in panels, (see link above), only instead of a straight seam, that produces a flat sail, you fuse the panels together on a very, very slight curve.
Too much curve in a sail that is broad seamed results in a sail that will keep that shallow "bowl" shape even on the wrong tack, unless the wind is strong enough to punch it in."

Now whether this helps or not I don't know nor do I care but as to date this conversation seems to be about the definition of an English word when one person's first language is not English.

How about you two either get your own forum or call it half time and continue this conversation in Dutch and leave the rest of us in peace.

BTW:- If this has already been covered I still don't care. Instead of working on my new boat I think I'll go ride my bike.
