I use a 10' closet dowel. Plasti-dtipped about 2' of one end, put a point on the other, and rubbed the whole thing down good with vegetable oil. I still use an anchor up front, but pin the back to avoid turning on the anchor in slick water.
One thing I've learned, the rope or whatever you use needs to be able to slide up and down the pin easily or any wave action will pluck it out of the bottom right quick.
If you're not living on the edge, you're taking up too much space!
