Drijflags

Drijflags are a type of nautical marker used to indicate submerged obstructions or hazardous areas in waterways. Unlike standard buoys that are typically anchored to the seabed, drijflags are designed to float freely on the surface of the water, often tethered to the obstruction they are marking. This free-floating nature allows them to move with currents and waves while still providing a visible warning. Their primary purpose is to alert mariners to potential dangers such as submerged rocks, wrecks, or debris that could cause damage to vessels. Drijflags are often brightly colored, commonly red or yellow, to enhance their visibility. They may also be equipped with reflective materials or lights to be seen at night or in low-visibility conditions. The term "drijflag" itself is believed to originate from nautical terminology, with "drij" potentially relating to drifting and "flag" referring to their flag-like appearance. Their use is particularly important in areas with fluctuating water levels or where traditional fixed markers might be impractical or impossible to install. By providing a visible and mobile warning, drijflags contribute to navigational safety and the prevention of maritime accidents.
