Sure would be interesting, even stupid, if English speaking kite companies printed "mast" on their LEIs referring to the STRUTS!
Of course they would never as it is simply the wrong term!
And it has become common practice to use the term "strut less" for LEIs with out said vertical structural element.
Can you fathom referring to this component as a "mast"?
Wake up people, just because the worlds leading Kite Board Hydro Foiling country uses the word "mat" does NOT make if correct to keep calling it such in English!
In addition it is so easy to see who could be the founding father of the base of most all of our current designs calls this part.

He would have NEVER even considered calling a STRUT a mat (French) mast (English)!
