Our introduction to Cuba was a little hectic. No answer when we called ahead at the 12 mile limit, which is protocol for entering Cuban waters. This was not unexpected. We had been told to just call again at maybe 3 miles. Anyway after a few tries no one answered and we just continued into the Harbor. Perhaps it was best to just call the marina we found out later. After getting in near the marina a small boat came by and waved us to continue in. They motioned for us to anchor, we did and soon the Harbormaster came by and told us to pull in alongside the dock. We came in and again all they used were hand motions to tell us what to do. No one had a radio to call us to tell us what they wanted. Eventually we got the message to drop our anchor way out from the dock and back up to where they were standing. Sailboats generally don't back up easily so I suppose we were resisting a little after what we had been told to tie up on the port side. It all ended well and soon the officials came on board. First the doctor who only asked if anyone was sick. A very nice man who gave us a few pointers like drink the bottled water and not to buy food from street vendors. Next came the Harbormaster who needed to see passports, write everything down, and take all kinds of pictures of everything in the boat, including us. Finally another individual came by with a dog who walked around everywhere at least twice. Everyone was very welcoming and courteous. No one even hinted of wanting any kind of a tip. We found out later that it would cost them their jobs if they accepted anything from us. By this time is was getting dark and we were all tired, and the mosquitoes and no-see-ums were invading. We were settling in for the evening when we got one more visitor from Customs. This was a surprise. He informed us that when we do leave the marina to go into town or whatever we must take with us only personal items, no import he keep saying. He was very clear about this rule. We found out later that this was a new rule as of Jan. 2018 to prevent any boaters from bringing gifts of any kind to the Cuban people. Money was OK but nothing else. We had some items we had intended to give to Cuban friends but now could not. They made it clear they would check our bags when we left the marina grounds and that they did. Not every time but we took no chances.
