In a meeting situation on the Great Lakes, which vessel sounds the first passing signal?

In a meeting situation on the Great Lakes, the vessel that sounds the first passing signal is the vessel downbound with a following current. This is based on the navigational rules designed to promote safety and clarity when vessels are navigating in close quarters.

The reason the downbound vessel has the priority to signal first is primarily due to its momentum. A vessel traveling downbound is typically moving faster due to the assistance of the current, which puts it in a position to make navigational decisions more efficiently. By sounding the first signal, the downbound vessel communicates its intentions and establishes the passing protocol for both vessels involved.

Understanding this also emphasizes the importance of effective communication and adherence to navigational rules to avoid accidents, particularly in the sometimes crowded conditions found on the Great Lakes. The expectation is that the upbound vessel will respond and sound its passing signal afterward, following the established protocol. This orderly exchange reduces confusion and fosters safe navigation practices among vessels in transit.
