My snubber is about 20 feet long; when deployed, the point attaching to the chain is under water about ten feet in light winds/currents (I cannot see it, but the water here is very polluted). The main reason for the "snubber" (for me) is to take all the load off the windlass and put it on the main deck cleats, not to snub the anchor chain (absorb tension in the rode). I let out more chain (have more scope) for that purpose.
