What types of VDS are there?

The types of Visual Distress Signals (VDS) used for boating safety are categorized as pyrotechnic and non-pyrotechnic. Pyrotechnic signals include flares, rockets, and other devices that burn brightly to attract attention, especially in emergency situations. These are effective for long distances and can be seen from far away, making them crucial for signaling distress.

Non-pyrotechnic signals, on the other hand, encompass various devices such as signaling flags, reflective mirrors, and electronic devices like whistles or lights. These types of signals do not rely on combustion and can be used repeatedly, providing an alternative for boaters in need of assistance without the need for explosive materials.

This classification is essential for understanding the appropriate tools to use in emergencies on the water, as each type serves specific circumstances and environments. The other options, while they may involve differences in signaling methods, do not appropriately represent the recognized categories of visual distress signals in the context of boating regulations and safety protocols.
