Sculling is a pretty cool thing to do. If the idea appeals the obvious thing to do is rig up a pair of thole pins (to be honest a rowlock will suffice) on the stern of your dinghy and have at it.
Does depend somewhat on your dinghy of course. Inflatables are not the best nor are today's typically lightweight and tippy fibreglass things but something with good directional stability is worth a shot.
Succeed and admiring glances will be your reward. Fail...well lets just say that standing in a dinghy in the middle of a mooring field going round in circles does not increase your overall standing in the community.
Trust me, I know.
btw....skulling a sub 30' engineless craft is a whole heap different to trying to punt something with a bloody great lump of cast iron under the cockpit, !!!!
