The One-Third Rule on Fuel Use

It is always important to ensure you monitor your fuel supply and carry extra fuel. When operating a watercraft, always abide by the 1/3 rule: use 1/3 of your fuel to get to your destination; keep 1/3 of your fuel to get back to shore; and keep the other 1/3 as a reserve in case of emergency.


REMEMBER: The basic guideline for estimating the amount of fuel needed for a trip is one-third for the trip out, one-third for the return trip and one-third as reserve.
