it was right between that Lighthouse at the bottom of City Island and Kings Point. Go through there all the time along with probably hundreds of other boats a week and no issues!
You were SOUTH of Steppingstone!!! If you've done this before and not hit a rock you were lucky. There is a large triangle littered with rocks marked by the lighthouse and two buoys near the Kings Point shore. Only safe route is north of the light or south of the two buoys.
