What is the characteristic of Georgetown Reach Range Rear Light?

The Georgetown Reach Range Rear Light is characterized by its light pattern of an isophase red light that flashes every six seconds. This is indicated by the term "Iso R 6s," where "Iso" refers to isophase and "R" designates the color red, with "6s" specifying the duration of the flashing sequence. This distinctive pattern helps mariners identify the light and its location, distinguishing it from other navigational lights that may have different flashing sequences or light characteristics.

Understanding the specific characteristics of navigational aids, such as the Seattle Planning and Scheduling Professional (PSP), is crucial for effective maritime navigation and safety. The accuracy of identifying such characteristics relates to ensuring proper communication and operation within maritime environments, which is of utmost importance for mariners navigating through the Georgetown Reach area and others.
