How many miles north of Fort Niagara must vessels pass to avoid the Niagara Bar?

To safely navigate and avoid the hazards presented by the Niagara Bar while approaching from the south, vessels must pass at least 1.7 miles north of Fort Niagara. This distance is crucial because the Niagara Bar is an underwater formation that poses a significant risk to vessels that come too close, particularly during fluctuating water levels or adverse weather conditions. Understanding this distance helps mariners ensure their safety and the safety of their vessels as they navigate the waters of Lake Ontario. Proper awareness of navigational markers and safe distances from such hazards is vital for effective seamanship and maintaining safe travel routes.
