Description
Ensure diver safety with our Alpha: Diver Down, Keep Clear flag, a critical maritime signal used to indicate that divers are in the water. Whether operating in open water or near busy channels, this flag helps communicate a clear warning to nearby vessels to proceed with caution.
This Alpha flag is manufactured in the United States from high-quality nylon for reliable performance in marine environments. Its lightweight build allows it to fly with ease in light winds, while its bold blue and white design ensures strong visibility on the water. Double-stitched seams reinforce high-stress areas for nautical use.
Available in sizes 0, 2, 3, 7, 10, and 14, this flag can be tailored to your vessel’s size and visibility needs. Multiple finishing options, including bronze snaps and rings, brass grommets, or line and toggle, allow for easy attachment and compatibility with your existing rigging.
