I purchased an Infusion this year and kept my 2000 Nacra 5.5. I would like to use the Infusion mast, Main Sail, boom, spinnaker, spin gear on the 5.5. Any reason why this would be a bad idea? I normally sail the 5.5 with a spinnaker solo but I like the idea of the F18 lighter wing mast. I set it up this weekend in the yard and it looks like it will only require minor tweaking to make it work.
