Bernard Crick said this quote

Monarchy is like a splendid ship, with all sails set it moves majestically on, but then it hits a rock and sinks for ever. Democracy is like a raft. It never sinks but, damn it, your feet are always in the water. That is a good metaphor, for raft, he implies, is simply swept along by the tide or the current; one can with a paddle or a plank steer a little to stay afloat, trim forward direction slightly to left or right, perhaps even slow down or speed up a little, but there is no turning back against the current of democracy.
