We chartered a Moorings 474 PC from the 5th to the 17th of May. During the boat check-out, I asked about a lock for the dingy. I was told "no, just take the little plastic clip on the coiled wire with you". I left it at that and that is what I did. My biggest concern was the Full Moon Party at Trellis Bay. No problems at all. Secretly I thought, it would have been a good thing if someone stole that dingy with that awful junk motor! Not really, because we experienced a dingy theft about 12 years ago and that was a big hassle! Incidentally, it was impossible to lock the boat! It would lock, but the lock could be easily defeated by sharply lifting up and sliding left at the same time. If you must lock things up, bring your own cable locks. One for the dingy and one for the boat. I'll say it again, we had no problems.
