What does the LCAC hand signal of the right arm extended downward moving to the horizontal position indicate?

The hand signal of the right arm extended downward and moving to the horizontal position specifically indicates "slow down." This gesture is commonly used in marine operations and training to effectively communicate with operators of various vessels, including LCACs (Landing Craft Air Cushion). The downward position of the arm represents a request to reduce speed safely, ensuring that operational safety is maintained during movements, particularly in potentially hazardous environments where precise control is essential.

Understanding these signals is crucial in maintaining safety and coordination onboard, especially in scenarios where verbal communication may be hindered by noise or distance. Proper interpretation and execution of hand signals help prevent accidents and ensure that all crew members are aligned in their actions, which is fundamental to successful maritime operations.
