I remember Fin & Tonic! Last evening, I called the phone number I got from SIM, and talked to the lady listed as the boat's captain (or at least the one who made the slip reservation). She lives in San Juan, Puerto Rico, which fits. I described the circumstances and what I wanted. She said she did not know anything about any drone, but said the operator might be her nephew and that she would talk to him and give him my phone number. I immediately followed up with a very detailed text message, and multiple ways to contact me. No joy yet.
