How much of your fuel should be reserved for emergencies according to the third rule?

Reserving a portion of your fuel for emergencies is crucial for safety while boating. The recommendation to reserve one-third of your fuel (1/3) aligns with best practices for ensuring that you have enough fuel to return to shore or reach a safe area in case of unexpected situations. This guideline provides a buffer in the event of changes in weather, mechanical issues, or needing to navigate away from unexpected hazards.

A reserve of one-third allows for some leeway in fuel consumption as well as the ability to adjust your boating plans in the face of unpredicted circumstances. It is essential to arrive at your destination without the risk of running out of fuel, particularly in remote areas where assistance may not be readily available. Following this guideline helps ensure that both the boater and passengers remain safe and are able to react appropriately should an emergency arise.
