How Much Weight Can a Kayak Hold?

If you’re currently looking for a new kayak, then you’ve probably come across the term weight limit or weight capacity in your research so far.

Maybe you’re curious about how flexible these weight limits are, or maybe even how manufacturers come up with the weight capacity for each kayak. 

Every kayak will have a weight limit, but not every kayak is the same, so maybe you’re wondering what sized kayak or what type of kayak would be best suited for your weight.

Well, if any of these suggestions have aligned with your thoughts then you’re just in the right place as we’ll be answering any questions you may possibly have about the weight capacities of kayaks.

What is meant by a kayak’s weight limit?

The weight limit of a kayak is the maximum weight number given to a kayak by the manufacturer to help consumers find out what type of kayak is best for them. This weight limit covers the weight of paddlers on board and also any gear or equipment that they may have with them.

However, the weight capacity of kayaks is not always determined in the same way by manufacturers and some just follow their own methods of assigning a weight capacity as there is so no set industry standard of how to work it out.

Ultimately, the weight capacity of a kayak is the total weight that the kayak can carry at once whilst still being able to float on the water. Although, if a kayak has a 300lb weight capacity, it doesn’t always mean that it is suitable for someone who also weighs 300lbs, we’ll touch on this more so further down.

How is the weight capacity of a kayak determined?

There are no set industry standards to determine the weight capacity of kayaks, however, three are three main factors that manufacturing companies take into consideration when assigning a weight capacity to a kayak - the length of the hull, the width of the kayak, and also the water displacement volume.

As a consumer, you won’t have to worry about using any of these factors, however, if you want to achieve optimum performance when paddling your kayak (high speeds, easier maneuverability) then you’ll need to do a small calculation to work it out.

The right size kayak for your weight should have a maximum weight capacity that’s around 125lbs more than your current body weight. Another way to work it out would be to reduce the manufacturer’s assigned maximum capacity weight by around 30-40%.

This is not the only thing you’ll need to consider though. If you’re going to be taking extra equipment and more than one passenger on board then you’ll need to add that into the calculation as well.

The formula you’ll want to use is:

Total Load Requirement/0.7 = Maximum Weight Capacity

So if we’re putting this formula into context, say you weigh 150lbs and you’re taking 20lbs of gear on board your kayak so the total weight on board will be 170lbs, you’ll need to multiply this number by 0.7, to figure out the recommended weight capacity of a kayak you should use, which will be around 243lbs.

Or if optimum performance is a priority, then you can use a different formula to work out the performance weight limit.

Maximum Weight Capacity x 0.7 = Performance Weight Limit

E.g 250lb weight capacity on a kayak x 0.7 = 175lb weight limit to get the best performance out of your kayak.

Should you max out the weight capacity on a kayak?

No, you should try your hardest to not max out the weight capacity on a kayak. If you’re maxing out the weight capacity, there’s a high probability that more water will come through the scuppers adding more additional weight to the boat and increasing the risk of the kayak starting to sink or capsize.

What happens If I go over my kayak’s weight capacity?

Going over the kayak’s weight capacity by a few pounds is not going to make too much of a difference. However, the more weight you add to the kayak the more difficult it will be to paddle as you’ll have to work your arms harder to shift the weight of the kayak around.

A kayak that is fully loaded to maximum capacity or over can also lose stability, which is not ideal especially if you plan on fishing on your kayak, if the weight is also not evenly distributed then you run the risk of it capsizing from merely leaning or turning around on the boat.

The extra weight will also make the boat sink lower in the water which will increase the risk of capsizing.

If you’ve overloaded your kayak, then you’ll find it more difficult to build high speeds, so if you want to participate in races on your kayak then you’ll want to have as little on board as possible.

What is the kayak with the largest weight capacity?

Here is a short list to give you an idea of the average weight capacity of various kayaks:

  • Recreational Kayak: 250-300lbs
  • Touring Kayak: 350lbs
  • Sit-on-top Kayak: 350-400lbs
  • Tandem Kayak: 500-600lbs

If you weigh between 175-200lbs you should seek out a kayak that has a weight capacity of 350-400lbs. If you weigh between 250-300lbs then a kayak that has a weight capacity of 500-600lbs will be best suited for you.

There are kayaks out there that are suited for heavier loads, for instance, the Sea Eagle 380x Kayak has a weight capacity of 750lbs.

Do single or tandem kayaks have a larger weight capacity?

Tandem kayaks have a larger weight capacity than solo kayas as they need to be able to hold the weight of more than one person at a time.

It’s important to consider the weight limit when choosing a tandem kayak as you’ll need to bear in mind the weight of both paddlers and any additional gear on board.

Ideally, both paddlers will be of a similar weight when on a kayak, otherwise the weight can be unevenly distributed and cause the kayak to sink down on one end. The heaviest passenger should always sit in the back.
