How Much Weight Will Your Pontoon Boat Need To Carry?

Gas

Gas is frequently overlooked when you are considering how much weight your pontoon boat will need to carry. Gas typically weighs about 6 lb per gallon.

The average pontoon boat carries between 20 and 35 gallons, which amounts to between 120 and 210 lb of weight.

If you want to carry extra fuel on board so that you can refuel as you go, you will need to consider this weight as well. 

Live Well

If you will be using your pontoon boat for fishing, a live well either for bait or to keep fish fresh is likely something you’ll want on your boat.

Generally, a live well holds between 15 and 30 gallons of water. Big livewells designed to hold a lot of fish can occasionally hold up to 50 gallons.

A gallon of water weighs 8.6 lb, so a 15 gallon live well weighs about 130 lb, a 30-gallon live well can weigh 250 lbs, and a 50 gallon live well can weigh a whopping 430 lb.

This is a significant additional weight for your pontoon boat that can be easy to overlook. 

Accessories

The wide range of accessories that you may want to add onto your pontoon boat all contribute to the weight. The bimini, anchor, ski deck, and more all add to the overall weight. 

While these accessories may not significantly increase the weight, when added together, you can expect them to result in at least a couple hundred pounds of added weight. This is worth considering if you are trying to fully load your pontoon boat

Supplies

Most people do not take their pontoon boats out for very long voyages, so the weight of supplies is usually not a hugely important element to consider. However, if you are trying to work out your boat’s weight to the last ounce, it is certainly worth keeping in mind the average supplies you’ll be carrying with you. 

A 24 pack of beer or soda generally weighs about 36 lb. If you’ll be bringing several 24 packs with you, this weight can add up. High-end coolers like the Yeti weigh around 30 lb, and when filled with ice, food, and drinks they can easily way 60 or 70 lb. 

Skis or wakeboards, surfboards, and other things you may want to take on board will also contribute to the overall weight.

Engine

Needless to say, an engine is an absolutely essential part of your pontoon boat. However, it also contributes to the overall weight of the boat. 

When the engine is in the water, it may not contribute to the weight of the boat as much, but when you lift it, it can weigh down your boat. How much your engine weighs depends on how much horsepower it has.

An engine of around 40 horsepower will typically weigh around 220 lb. An engine of 150 horsepower can weigh as much as 460 lb.

An engine of 300 horsepower can weigh a whopping 575 lb, a significant contribution to the overall weight that your boat is carrying.

People

Perhaps the most obvious and important weight that you’ll be considering for your pontoon boat is the weight of people.

It can be pretty awkward to ask your guests how much they weigh before they get on the boat, so you will typically be left estimating how much your guests weigh in order to know how many people to invite. 

Once you add up all the things that can contribute to the weight that your pontoon boats can carry, make sure you err on the side of caution when inviting people to make sure that they don’t overwhelm your boat. 

How To Tell If A Pontoon Boat Is Overloaded

The best way to avoid overloading is to look at the maximum amount of weight that your pontoon boat can carry and stay inside that weight.

However, if you have had trouble with your estimate or somebody brought a friend unexpectedly and you’re wondering whether they put the weight over the capacity but aren’t sure, you can look at your pontoon boat to determine whether it is overloaded.

Unfortunately, when it comes to pontoon boats, they often look fine even when they’re overloaded. This is thanks to how high they tend to sit in the water and the stable platform.

At a glance, it may appear that your pontoon boat is stable even though it is severely overloaded.

However, by looking at the water line against the pontoons, you can help determine whether the boat is overloaded. The water line should not go above the middle of the pontoons. 

Furthermore, the water line at the stern should be lower than the water line at the bow. The stern should be lower than the bow so that the pontoon boat will be able to cross over waves instead of taking water over the bow.

A boat that is overloaded at the bow will tend to nosedive into waves, which can result in the boat sinking.

Weight Distribution

The overall weight on your pontoon boat isn’t the only thing you need to keep in mind when you are trying to decide whether your boat is loaded safely. How weight is distributed is also extremely important. 

This most often comes into account when people are moving around on your boat. Because a pontoon boat has a flat surface that makes it comfortable for people to move around, it can be very easy for people to throw off the weight distribution. 

Everyone may enjoy riding at the bow when the boat is underway, which can overweight the bow and cause it to take on water.

Your group may run to the side of the boat if they see something interesting, which can cause your pontoon boat to list to that side. 

Usually, these changes in weight distribution don’t cause serious problems and can quickly be corrected by telling people to move.

However, if everyone moves forward at the same time as a big wave comes, it can result in your pontoon boat taking on a lot of water.

Don’t be afraid to be straightforward with your passengers about why it’s important that they distribute their weight.

Is It Okay To Load Your Pontoon Boat To The Maximum Capacity?

As a rule, you should never allow your pontoon boat to be loaded up to its maximum capacity. Even though it may be fine starting out, a change in weather can quickly cause problems for a boat that is loaded up to the max. 

A pontoon boat at maximum capacity will be less agile and tend to sit lower in the water, which means it can take on water from waves more easily.

Your pontoon boat can become swamped and begin to sink faster than you may expect. 

There’s no hard-and-fast rule about how far below the maximum capacity you should keep your pontoon boat, as it depends on the expected conditions such as weather and waves.

However, it’s a good idea to always leave at least several hundred pounds of leeway between the maximum weight and how heavily you load your boat.

Enjoy Loading Up Your Pontoon Boat

Inviting all of your family or friends out on the boat is one of the reasons you got a pontoon boat in the first place. After all, this is one of the most passenger-friendly boats that you’re likely to find.
