What is the regulation governing the placement of draft marks?

The regulation governing the placement of draft marks is found in 46 CFR 97.40-10. This regulation specifically outlines the requirements concerning the draft marks on vessels, which are essential for ensuring proper compliance with navigation and safety standards. Draft marks are important indicators of the vessel's draft, or the vertical distance between the waterline and the bottom of the hull (keel), and they play a significant role in maintaining stability and safety in various water conditions.

Regulations like this are crucial for port state control inspectors to verify that vessels adhere to established safety guidelines, which helps to prevent accidents related to vessel stability and draft issues. Proper placement and visibility of draft marks are essential for the crew and officers on board to monitor the vessel's loading condition effectively, ensuring safe navigation in confined or shallow waters.
