When arriving at a navigation lock, what is the order of priority for vessels?

The prioritization of vessels at navigation locks typically follows the principle of commercial necessity, where commercial vessels receive precedence due to their importance in the supply chain and economic activity. Therefore, military craft are prioritized first. Following them, commercial vessels are next, reflecting their larger cargo capacities and the need to ensure that goods and services are efficiently transported. Next in line are fishing vessels, which play a vital role in the economy but are generally considered to have a lower priority than commercial shipping. Finally, pleasure craft are given the last priority, as they are not essential for commercial activities and usually require fewer resources and time to navigate.

This order of priority reflects the operational requirements of navigation locks to maximize efficiency and minimize congestion. Understanding this sequence helps boaters navigate these areas safely and in accordance with regulations.
