Which of the following locations is a common anchorage during storms on Lake Ontario?

Cape Vincent is recognized as a common anchorage during storms on Lake Ontario due to its strategic geographic positioning. This location provides significant protection from strong winds and rough waters that can occur during storms, which is critical for vessels seeking safe harbor. The natural features of Cape Vincent offer an inlet that allows boats to anchor securely and avoid the harsher conditions present on the open lake.

While Port Weller and Buffalo are also important ports on Lake Ontario, they do not offer the same level of shelter from storm conditions as Cape Vincent does. Windsor, located on the opposite side of the lake in a different body of water, is not ideal for vessels navigating the challenges posed by stormy weather on Lake Ontario specifically. Therefore, Cape Vincent stands out as the most reliable location for vessels in need of refuge during inclement weather.
