🔍 Key Concepts

• Inland navigation lock regulations for vessels waiting to lock downstream • Safe stopping distance and room needed for large commercial vessels exiting a lock • Why rules require a minimum distance above (upstream of) the lock for waiting downbound vessels

💭 Think About

• Think about how much clearance a large tow or commercial vessel might need to safely exit a lock and maneuver before encountering small craft waiting to enter. • Consider that the required distance is set for safety and traffic flow, not convenience—would it be relatively short, or more conservative? • Ask yourself which distance seems consistent with keeping the approach to and from the lock completely clear for larger, less maneuverable vessels.

✅ Before You Answer

• Verify what the Corps of Engineers / inland lock rules specify as the minimum upstream distance for downbound boats awaiting their turn. • Make sure you are thinking of descending (downbound) traffic ABOVE the lock, not below it. • Check if the distance sounds large enough that a vessel exiting the lock at slow speed would have ample room before reaching the waiting line of boats.
