Never got into naming the
dinghy. Maybe if my better half wants to name it something we will, but to me it's just "the dinghy". Our life jackets and harnesses have our ship's name on them.
You should make the
outboard and dinghy totally un-stealable though. Beyond locking it up, spray
paint it bright pink with yellow spots or something. If you have a
wood transom, get your Dremmel with router kit and write the
registration number in or something of that sort.
Use big chains, big locks, and keep it away from the jerk at the dinghy
dock with a cable full of meat cutters.
