@ tost,,, hmm,, could be. I watched the AIS moving along the berth and it matched the location and showed the Punta Espada name. But I know there is a patrol vessel by the name 7.de Agosto too. Here in the port is also the 11 de Noviembre and 20 de Julio. Somtimes even AIS signals jump,,means when ships are very close, they interchange.

It's PZE-47
