You would have thought they might have asked for help and looked for it! I had a interesting experience once at Sandy Isle where a powercat pulled up next to us and dropped about 12 feet of chain out in 8 feet of water. They jumped in the dinghy and went ashore to hike the island. Took about 2 minutes for the 15knot wind to start moving the boat. Once the water got to 12 feet it took off! Surprising how fast a boat will drift. We jumped in the dinghy and retrieved it. While we were anchoring it properly they came back from their hike and starting screaming like lunatics about us stealing their boat!
