We are chartering out of Antigua in a couple of months one way to St. Martin and want to drag a couple of lines whenever we're sailing. I tried to check on the government website for each island to see what the regulations are, but they are less than clear so I decided to email the charter company. According to the charter representative we will not need a fishing license for any of the islands we will be transiting - which include Antigua/Barbuda, St. Barths, St. Martin. There are marine reserves at least at St. Martin and I think probably the other two islands where you are not allowed to fish, or at minimum would require a license. FWIW, we were also informed that spear fishing is not allowed in Antigua.

The above said, I am watching this thread too see if Zanshin comes back with the same information that I received from the charter company.
