Sealand

Because the beach at the campsite has been completely washed away by the heavy wind and waves in the spring, we thought that the Sealand would finally arrive to spray sand on the beach. So that we could play on the beach and bask in the sun again.
But it turned out that the boat is used for maritime and coastal services. It is especially for deploying yellow buoys. After these were turned off he left again without adding anything else.
