I believe the SX wings can be retrofitted for older Hobie 18's, but this would involve structural strengthening plates under the crossbeams and reinforcing anchor points for the wings. Again, this is not a cheap option for the 18, but a comfortable one (not a good performance addition). If you are really serious about wings, you could always build something to the effect of what is on the Hobie Fx. It has an extended trampoline past the hulls maybe 2 feet and is at an angle. It is supported by small beams from the crossbeams I believe.
What would be really interesting is to try this with windsurf mast sections for the carbon beams, and retrofit trampoline material, kind of like a sling raised at a 30 degree angle going out from the boat.
I guess my belief is that unless you purely desire comfort and more room for people on board, then by all means go with wings, but if you are looking at the performance spectrum, then ditch the wings and invest in good trapeze gear.
