Someone from Autodesk posted an Excel to create points for this.
You set Inventor to automatically create a 3D Spline through the points on import for your sweep path. I meant to keep this one as this question comes up often, but now I can't find it.
If you find the url to the thread please post it here.
I only tried it with a circular profile, not a rectangular profile like your fin. I would be concerned that the fin orientation might twist. If it does then sweep with guide surface might be the ticket. The other concern I would have would be the number of loops.
Hope someone here turns up that Excel.

Here is one, but this isn't the one by the 'Desker. At the time I didn't realize that Inventor could automatically create the spline. http://discussion.autodesk.com/forums/thread.jspa?messageID=6053371?

Here is a solution. I didn't experiment with the dimensions to try to get to look like yours. Good luck.
