I was a couple miles away when it happened. I heard the radio call and looked around and saw the smoke and flames. There were several boats nearby. Someone (I assume the charter captain), called I'll be there in 30 seconds, and picked up two people. Another vessel had the third. Two fast boats near me headed that way ASAP as well. Kudos for everyone dropping what they were doing and pitching in. From radio traffic all three people were ok. The boat burned for hours, and I assume sunk. The only description of boat I heard was 21 ish fiberglass.
