No, a drydock does not have to be made of wood. How would battleships and aircraft carriers be built if they had to use floating docks? All that is required of a drydock is that it can be closed off and the water pumped out. Or bailed out in the case of the ancient versions, I guess. The Greeks probably didn't have 'pumps' and had to use buckets. :) But I had the impression that drydocks were a fairly late innovation. Ancient ships used to be small enough that you could just build them on the shore and then drag them into the water.
