Ohhh no, you do not want to play in the Mona Passage! Been there, done that, was called Tropical Storm Claudette the next morning. Also, Mona is kinda off-limits, I don't remember if it was military or research
or something, but they do allow you in for hiding from the weather
You really want to go east to the Spanish Virgins with Culebra as the hang-out. If you want to go further, sail all the way up to Virgin Gorda. If you want more, look north of Gorda on your map for that one island most cruisers skip.
