Continuing on last weeks tip of locking your dinghy to your boat or tender sometimes you need to lock it to a dinghy dock as well.
We also carry a really long thick double loop security cable (something like this but I think ours is thicker - we got it at home depot) as well for places we are worried their really is a threat of the dinghy going missing. It fits through most chalks and/or through small spaces on the dock making it easy to find a place to lock the dinghy too. We can slip it around something and lock it right bake to the engine. This has worked well for us. Many people carry chain but that gets heavy and there is always a rust factor. We've had very little rust on the cable lock so we don't mind using it for locking the dinghy to the boat as well (unfortunately yes, they do go missing off the back of boats all the time.)
