There are lots of things that could be done. The restaurants could get together, and pay for someone to man the dock, and take care of things, The authorities could be more active.. or perhaps just active!

The old saying, "Lock it or Lose It!" always applies.

You would not leave $7000 cash just sitting on the dock, so why leave a tender there, unsecured (Same value).

Also, Bring your own padlock from home. All Sunsail padlocks use the same key... Kinda scary fact...

Be safe!
