I did drag my crew once and it was a pretty frightening sight. We had capsized and I had just climbed back on board, my crew was struggling to get over the front beam, lost grip and slipped back into the water. The boat was still moving slowly through the water as I had not yet gotten everything situated after righting the boat, and crew exited from under the rear beam. My thought at this point was "holy crap, now my crew is separated and I've got to get the boat turned around to make a pick-up". The wind was a solid 20+. By freak coincidence, the knot at the end of the righting line snagged the crew's trapeze hook just out of reach from behind the boat and the crew at this point was being dragged with just enough tension on the line to prevent it from being unsnagged from the harness hook. The dragging was actually forcing her underwater despite the lifejacket. Keep in mind that all this took just a few seconds to take place. Another couple seconds later and I had the boat was stopped enough to unsnag the righting line, get her back on board and all ended well.
