Extend Your Range with Auxiliary Fuel Tanks

Auxiliary fuel tanks can help you fish farther and longer.

Most modern sport-fishing boats offer plenty of fuel capacity for a day of fishing. Yet on occasion, you might need more, particularly if you plan on multiday trips to distant, remote areas such the Dry Tortugas west of the Florida Keys, the uninhabited islands of the Bahamas or down the Pacific coast of Baja California.

Fortunately, a number of products lets you safely add auxiliary fuel capacity and more fishing range. The operative word is “safely,” particularly when it comes to the highly flammable nature of gasoline. Never store fuel in anything other than containers designed for such purposes, and never stow gasoline containers in a cabin or bilge where a leak or vented fumes might lead to a catastrophic explosion or fire.

Also, be careful about adding and placing the weight of extra fuel in your boat. Remember that gas weighs 6.1 pounds per gallon, while diesel displaces 7.1 pounds for every gallon, and a large, full fuel cell can shift a boat’s center of gravity, and affect a boat’s performance and seakeeping ability.

Let’s look at some ways to carry more fuel, without tearing your boat apart to install larger tanks, when you want to extend your fishing range.
