When must scuttles be secured?

Scuttles should be secured at all times except when open for inspection because this practice is crucial for maintaining the safety and integrity of the vessel. Securing scuttles prevents unauthorized access and minimizes the risk of water intrusion, contributing to the vessel's overall stability and buoyancy. When scuttles are not secured, there is a significant risk associated with them potentially being left open, which can lead to flooding, especially if the vessel encounters rough conditions or an emergency situation. The requirement to keep them secured when not in use ensures the crew can operate the boat safely and efficiently under a variety of conditions. This practice aligns with established safety protocols that ensure a vessel is always in a state of preparedness for any eventuality.
