Okay both me and the other half are British, the boat is British registered. We have been to Cuba, 2009 and 2011.
Obtained our B1/2 visas in Cuba, Havana. sailed on to Florida
in 2011. Immigration a little hostile but no problems.
We produced zarpe from Cayman Islands
, no passport stamps in Cuba.Nobody questioned the difference in dates.
We saw a number of US registered boats on the south side of Cuba. We met US citizens who were working in colleges and hotels in Cuba.
The dive resort at Maria La Gorda, in 2009, was full of US holidaymakers, they flew to Mexico
first and then on to Havana.
Cuba is a gem, the waters on the south coast are pristine, the fishing
is unbelievable and the people are delightful.
Go now before it opens up to the USA and changes forever :-)
