If friend, the colored strips mean those of our flag. MGR acronym in Castilian of the NAVY OF WAR REVOLUTIONARY, although I believe that this ship is of the TGF troops guard borders. And forgive the delay in answering, I was in Cuba and there the internet is something prehistoric. I think we agreed on dates there. A greeting. Captain Carlitos.

Thank you Manuel. I've changed the title and category per your comment. Should new information become available I will adjust accordingly.

I'm pretty sure she is the cuban coast-guard ship 'BGC 080'.

Thank you for your input. The red/white/blue stripe (colours Cuban flag) on bow suggest official/government vessel....? If Navy, the title might read something like MGR 080...? I PM'd Captain Carlitos several days ago hoping he might be able to positively identify. Thanks again for your comments.

The presence of a kind of official seal on the side of the bridge and painted lines on the bow seems to point a coast guard or customs ship.

The number is 080.
