I know of an incident that occurred 15 years ago. A friend was the owner of the particular charter boat. It was on a mooring at Saba rock. The occupants went to bitter end for dinner. On the way back across the channel between Saba and beyc their dingy was hit by a high speed power cruiser. Several dinghy passengers were killed on impact. Litigation transpired for years. I don't recall the outcome. But nobody needs to be at risk for this sort of mishap. To travel without a light is illegal reckless and puts people's lives At risk. It's stupid.
