There are fleets of Cats at Cayo Coco on the north shore and a raft of Cats out of a place near Trinidad. There are a few out of Cienfuegos as well/ Santiago de Cuba, Cienfuegos are well protected and have facilities. Marina Hemingway is reasonable in a storm. Remember that if you are there, the south coast has over a hundred miles of mangroves. The Cats they have are all crewed yachts chartered mostly to Germans and Brits. They have not really lost any boats due to hurricane, but they are all manned during these times. Whether you could leave your boat without worry is another thing. I knew a few French Canadians that keep there boats year round, and you have to remember there are permanent live abards in Varadero and Marina Hemingway.
