Personally, I support the "child's wagon" approach. I'd let you climb aboard and pole it along if you like and I also like the sail idea. But I think it follows you and therefore it doesn't go anywhere if you climb aboard.
HOWEVER, I think you could "share" the spell with your familiar and climb aboard while the familiar moves ahead of it with the disk following the familiar.
