use a lobsterman's bait bag
I've had good luck using a lobsterman's bait bag stuffed with 3-6 pounds of rocks --- scoop the rocks up on the shore, keep 20' of rode in a second biat bag, dump the rocks out overboard before the paddle home.
It's a cheap and simple rig --- good for a guy as cheap and simple as I am.
Also I don't have to worry about getting bruised, nicked, or falling on grapples, nor have to deal with one more piece of bulky equipment in the car for the drive to the put-in.
