I mostly boat for diving. Occasionally, I need to be able to get the boat moving quickly while anchored (drifting divers, medical emergency, etc.)
One little trick that comes in very handy is to have a float and a quick release of some sort at the bitter end of the rode. If you have to get going, simply untie (or uncleat) your rode from the boat, disconnect the bitter end, and toss the whole mess overboard. Tend to business, and come back later to retrieve.
This also works for non-divers who foul their hooks on the bottom: Leave the anchor and rode, and go looking for a diver to unsnag it for you.
