Understanding and using sound signals are important for safety aboard, and sound signals are required to be used in certain situations. On this episode, we once again welcome Robert Rice to tell us which sound signals are most likely to be needed by Loopers, and which they are likely to hear on the waterways of the Great Loop. The Great Loop is the boating adventure of a lifetime! Loopers travel 6,000 miles aboard their own boats, cruising the New York State Canals, the Great Lakes, the inland rivers, the Gulf of Mexico, the Atlantic Intracoastal Waterway, and Chesapeake Bay. The route circumnavigates the eastern U.S. and takes most Loopers a year or more to complete.
