Cargo must be securely fastened to the LCAC cargo deck to eliminate the possibility of what happening?

The importance of securely fastening cargo to the LCAC (Landing Craft Air Cushion) cargo deck is primarily to prevent the cargo from shifting during transit. When cargo shifts, it can disrupt the stability of the vessel and potentially lead to dangerous situations, including capsizing or losing control of the craft. Properly securing the cargo keeps it in place, ensuring that the craft remains balanced and that the crew and equipment are safe while navigating.

While damage to the cargo, falling overboard, and theft are concerns, the primary issue with unsecured cargo in a moving craft is how the cargo's shifting impacts the overall operation and safety of the vessel. Securing cargo is a critical step in maintaining operational integrity during transport across water, especially on a vessel that experiences unique dynamics like an LCAC.
