How many life boat flares should be available on board?

The requirement for the number of life boat flares on board a vessel is based on safety regulations that ensure adequate emergency signaling capability. The correct answer indicates that vessels are typically required to carry a minimum of 12 flares. These flares are essential in emergency situations, as they provide a means to signal for help and increase the vessel's visibility in distress situations, ensuring greater chances of rescue.

The specific number of flares mandated can depend on various factors including the size of the vessel and its area of operation, but 12 is a commonly recognized standard in many maritime safety guidelines. Carrying this number equipped on board provides a reliable means of distress signaling, as flares are considered a critical tool in maritime safety for both commercial and recreational vessels.
