There you go. Even easier.
I keep my boat on a mooring in Staten Island's Great Kills Harbor. Check out the chart. When the tide is going out, you can be faced with up to a 2 knot current. If the wind is in an unfavorable direction and you have to tack, it can be next to impossible. The channel is narrow and leaves you little room for error. Running aground is a real possibility. Faced with a dead engine, outgoing tide, and unfavorable wind, I would anchor outside the channel and wait for a tow from a passing boat or for the tides to change
