Do the International and Inland Rules apply to both international and inland navigation?

• A. International Only
• B. Inland Only
• C. Both International and Inland
• D. Neither

Answer: (C)

There are two sets of rules for preventing collisions, and which one you use depends on the waterway you’re in. The International Rules govern ships on the open sea and in international waters, covering international voyages. The Inland Rules cover navigable inland waters within a country, like rivers and lakes. Because a voyage can span both environments, you follow Inland Rules on inland waters and switch to International Rules when you’re in international waters. So, both sets apply, depending on your location.
