The harbor lock is still under repair. Currently, there are no ships worth seeing in the harbor. Just an old shipwreck. So, nothing really worth seeing.

The Harbour gate failed in a recent storm due in part to a long-term lack of maintenance. As a result, the ships that were in the harbour all have been stranded every time the tide goes out. They have recently put shipping containers filled with aggregate where the gate was to keep water in as a temporary "fix"
