The Magnum basically just added a welded construction wing to a standard H18, the wing is the same length as the distance between cross bars. The H18 SX has a longer wing (maybe 18" in front of and behind the cross bars) and is rivetted together instead of welded. The longer wing is nice for getting weight to the back of the boat, and easier to have 2 people on the wire. A true SX also has a longer mast, vertical cut sail and had a spin option.
At some point, in the late 80's I think, they started adding reinforcement to the hulls at the shroud connection points and where the cross bars connect to the hulls. Not sure if this was for the wings or just needed in general. They added steel plates on the outside, not sure if they added fiberglass on the inside or not.
