Anybody else notice the head on the mainsail on the Infusion? Fairly big head, little roach.

This pic illustrates it well. Its shows the Older Hobie F18 main vs the Infusion main. IMG_7296.jpg

Then look at this http://www.ullmangz.it/ENG/Product_F18.asp

Wouter mentioned the hull shape and the mast, I would argue that the hull shape changes are insignificant compared to the rig and sail changes.

Changes in terms of importance in my opinion
1. mast
2. sail
3. race ready setup
4. hull shape
