Group hug!
Sorry don't have any info about Cuba except a friend sailed to Mexico then on over to Cuba, the Cubans put their stamps on a slip of paper which was placed in her passport. She was advised that she could throw it away when she leaves Cuban waters. I am told this was the way it is done for Americans. However, this was over ten years ago
Anyone have a similar experience? Also knew a guy that lost his boat on a reef in Cuba, he was rescued by the cubans and sent home by the Americans, he did not mention any repercussions about cruising in cuban waters (that was 12 years ago). Sorry my info is so out of date.
