Which statement is true concerning lighting requirements for Great Lakes vessels?

The statement about lighting requirements for Great Lakes vessels specifying that an all-round white light may be carried in lieu of the second masthead light and stern light is accurate. This provision allows for flexibility in meeting the lighting requirements, especially for certain types of vessels that may not be equipped with all traditional lights. In situations where a vessel is unable to carry the full array of lights, using a single all-round white light in place of the two specified lights helps ensure that the vessel remains visible and can be safely identified by others navigating the waters.

This adaptability is particularly relevant in maintaining safety and compliance while navigating the varied conditions found on the Great Lakes. It is essential for vessels operating in these waters to follow regulations that allow for proper visibility to prevent collisions. The use of an all-round white light, when correctly positioned, can effectively indicate the presence and orientation of the vessel to other vessels in the vicinity.
