On a boat, if your refer is old enough, it has the old school kid-killing latches to keep it closed. (The refers are pretty small usually, so only fairly young children can be killed in them, and possibly not at all, if they're wearing their PFD as they should be and therefore will not fit.)
Newer ones will have a jerry-rigged hook-and-eye latch or some variation screwed inappropriately into the brightwork. Brand new ones will have nothing, and then they will have a jerry-rigged bungee cord wrapped awkwardly around it about 12 minutes after leaving the dock.
Sailors will be still on the pier arguing with the harbormaster, "what do you mean you stopped selling block ice?"
