I noticed there are no fishing poles on the stern pulpit railing. It isn't as easy for a sailor to fish as it was when I was a kid, but I did find this article, if you're interested in a little self-caught dinner while adventuring through the islands.
Fishing regs in the Caribbean
"Fishing in the Caribbean can be a little confusing, as one island requires a permit and is strictly catch and release, and just on the horizon, the neighboring island nation is a complete free for all.
But don’t get your lures in a bunch. We compiled a list of all the Moorings Bases in the Caribbean, what to expect fishing-wise from each destination and how to get your fishing permits."
I don't know what "Moorings Bases" refers to, I haven't explored the rest of their website, but it seems like a yacht rental company. However, this is a decent start to getting a grip on Caribbean fishing laws.
