This is easily done in Rhino3D
Example:
Use the command 'Transform-Flow along curve' select letters, enter, select orig backbone, select new backbone, - done.
For best results the new backbone should be the same length as the orig backbone.

Great site Mike !!
Neat part is you can pick an airfoil, click on it and it opens in Notebook, now delete the heading and save the file as a .txt file.
Mastercam can 'Convert - Read' an ASCII file - select the airfoil txt file - read it in as points and 'voila' :
Welcome to the forum !!
I think I would draw 3 or 4 cross-sections of your blade (in the correct place and orientation) and then do a lofted surface between. Maybe a network surface to finish the blade end.
Alternatively, draw the cross-sections and a spline of the parting line and use network surface to make the top and bottom surfaces.
I don't see a need for a sine curve.
Good luck !!
Maybe try some google searching of 'boat props' for more ideas.
.
Again, use Rhino3D for that. Add control points, rebuild the spline, edit weight of control points, remove control points, move 1 or many control points at a time etc.
Rhino3D = great compliment to MC
