I'm sort of new to solidworks...

I'm trying to create a part in SW09 and I'm having trouble getting the loft feature to do exactly what I want.  I would really like to create this part without the split line through the middle but I am only able to create 2 seperate lofts instead of the 1 feature performing what I really desire.  The part isn't prfectly symmetrical, which also made it a little harder.  Perhaps there would be a better feature option to use in place of a loft?  Somebody help me, please!
