Cam's advise is correct. You might consider following that Moran tug with the barge on the hip. He'll be waiting for slack water as well. Note that slack water is not the same as high or low tide. Consult your tide and current tables. I offer the idea of following a tug/barge, if present, as advise due to the fact that they'll give you a good visual ahead of what the current is doing. Hell Gate is not misnamed.
