We have underwater lights and see tarpon at virtually every anchorage in the BVI. We saw a small feeding frenzy at daybreak one morning last November in Soper's Hole. We kept hearing rushing water and splashes, looked out the escape hatch and there were dozens of tarpon after a bait ball. After several minutes between the hulls the frenzy moved behind the boat, it went on for 10 - 15 minutes.
