How many flotation devices must a legal working boat possess?

A legal working boat must possess one flotation device per person on board. This requirement ensures that in the event of an emergency, each individual has access to a flotation device to enhance their chances of staying afloat and being rescued. The primary focus of this regulation is safety; therefore, having at least one flotation device available contributes significantly to reducing risks while on the water.

While the other options suggest having more than one flotation device, the minimum standard required for legal compliance is simply one device for each person in the boat, rather than a specific number like two, three, or four. It's essential to check local regulations as they may vary, but the guideline for a legal working boat centers on ensuring adequate flotation devices aligned with the number of people on board.
