Looks like the luff is at least a foot too short (maybe even 2 feet), hence, doesn't fit the boat. Check rigging manuals for the boat type, but usually the luff distance should equal (or around) the distance from the hoist point to the spin pole.

Anyone google or have the rigging manual for that boat, should be some indication on pole height / luff length, I'm doubtful that the pole is two feet low...


Looking at the pic, that kite almost look symmetrical with an offset douse patch... I'm with Paul on this, that ain't an F18 kite.
