I was in Trinidad in 2010 when the first attacks on the Trinidad to Grenada run (86 nm open water) started. A group of cruisers asked the Trinidad government to send a patrol boat once a week between Grenada and Trinidad so we could convoy. The government didn't think it was their problem. In 2010 there were 4,000+ boats stored in Trinidad. I understand there were approximately 1,000 boats in 2015. We left as did many of our friends.
Trinidad has a natural advantage for summer boat storage because it is below the hurricane zone. In 2010 it had a major boat industry with competing vendors in most categories. Much has changed.
