A common question when kayaking, especially for beginners, is “how much weight can a kayak hold?” This is one of the factors you need to consider when choosing a kayak, as going over your kayak weight limit could cause it to perform poorly, or worse, increase the risk of capsizing.
The question of how much weight a kayak can carry does not have a simple answer. This is because there aren’t any universal standards to measure the weight of a kayak. Each manufacturer provides its own maximum weight capacity, but how they arrive at this metric varies from one manufacturer to another.
Considering this fact, you should note that a manufacturer’s provided weight limit just shows how much weight the kayak can hold while remaining afloat. It doesn’t mean that this is the efficient weight for the kayak. Loading the kayak to its maximum weight could negatively impact maneuverability and efficiency in the water.
This article aims to break down what a kayak weight limit is in more detail so you can know just how much weight to load when kayaking.
How Much Weight Can a Kayak Hold: The Ideal Weight
As stated earlier, your kayak will perform poorly on the water if you put the maximum weight on it. While the kayak can remain buoyant, it will suffer from numerous performance problems.
Imagine a pickup truck with a loading capacity of 2,500 pounds loaded to the brim. Of course, the truck will still be able to move, but it will be a lot slower and put additional stress on the engine. This can negatively impact fuel efficiency.
This same principle applies to a kayak. When fully loaded to its maximum capacity, the kayak will sit lower in the water and move sluggishly. It will be a lot more difficult to paddle a fully loaded kayak around. The additional weight will sacrifice stability and maneuverability. Plus, you are more likely to get wet as a result of this.
What Should Be a Kayak’s Correct Weight?
A kayak’s ideal load is typically about 25 to 30% less than the rated maximum capacity. This doesn’t mean you can’t load your kayak less than that. What it means is that going beyond this recommended number will negatively affect your kayak’s overall performance.
What Goes Into Calculating a Kayak’s Weight Limit?
There are three important factors that manufacturers take into account when determining a kayak’s maximum weight. They are volume, width, and length.
Volume has to do with the kayak’s overall carrying capacity. When a kayak is said to be high volume, it means that the boat is generally stable and is a great craft for newbies. However, what it gains in stability, it loses efficiency.
Generally, higher volume crafts have larger weight capacities but are not as efficient as low volume kayaks.
Width or Beam
This refers to a kayak’s width at its widest point, which is typically its middle. A kayak’s beam has a significant influence on its overall stability, and a wider beam means that it can take on a higher load capacity.
The longer the kayak’s overall length, the higher the kayak weight limit will be.
How Much Weight Can a Kayak Hold: Common Weight Limits of Kayaks
From what we’ve covered so far, you should have a better understanding of how a kayak weight limit is calculated. One thing to always note is that there are various types of kayaks and the weight limit of one would differ from the other, even if they are constructed by the same manufacturer.
Inflatable kayaks are water rafts that have made leaps and bounds in recent times. They have become a viable option for individuals searching for a lightweight and highly portable kayak that can be carried around in duffel bags.
All inflatable kayaks are not created equal. They tend to differ widely in overall quality, features, and design. However, due to their high buoyancy, they generally have higher weight limits compared to hard-shelled kayaks of the same length. It isn’t surprising to see an inflatable kayak with a maximum weight capacity of 500 pounds.
A tandem kayak is named so because they are to support two people. These kayaks can either be sit-on-top or sit-in designs. They are generally much wider and longer than single-occupant kayaks.
By design, a tandem kayak is typically as long as 12 feet or more, and that means they are going to have a larger kayak weight capacity compared to others.
A fishing kayak is designed to be stable and tough. By their designation, you can tell that they were created to be stable fishing platforms. These kayaks typically have extremely wide beams to offer users the required stability to stand up when casting off.
These kayaks also require a higher weight capacity compared to other types. A fishing kayak has to hold plenty of fishing gear, trolling motors, reels, and rods. The additional stability and weight ensure that users can catch and reel in larger fish without the fear of capsizing.
These kayaks are generally sleeker, longer, and designed for long-distance paddling in a vast array of water conditions. They can be used in the ocean owing to their capability to handle rough weather.
Considering that touring kayaks are mostly used over long distances and trips that tend to span days, they are designed to hold a significant amount of gear. The gear can be stored in the hull or the stern without negatively affecting the kayak’s efficiency or speed. They tend to have a weight range from 295 pounds to 360 pounds.
These kayaks are designed to be used in calmer waters. They promote casual paddling as their design leans towards stability rather than efficiency or maneuverability.
Recreational kayaks were designed to aid beginners. The crafts help newbies to feel comfortable in the water, which is why they favor a generally wide design. Since they are designed to be used by beginners, they tend to have a kayak weight limit between 200 to 350 pounds.
How Does Weight Correlate with Optimal Performance?
If there is one thing we can deduct from what we’ve covered so far, it is this: a kayak’s optimal maximum load is different from the manufacturer’s maximum kayak weight limit. This might make you wonder how to balance loading up your kayak without affecting its optimal performance.
Well, a kayak’s optimal maximum load is typically lower than the manufacturer’s maximum weight limit. While the actual number will differ from one kayak to another, a kayak’s performance weight limit is typically just 65% of the maximum weight capacity given by the manufacturer. If you have a kayak or are thinking of purchasing one, you can use the following formula to determine the optimal performance kayak weight limit:
Manufacturer maximum kayak weight limit x 0.65 = Performance kayak weight limit
Certain manufacturers include this number along with the maximum weight limit. When calculating this, you should bear in mind that the total weight of a kayak also includes everything that is inside the kayak. This will mean the people, kayak paddles, supplies, and any other gear.
Here is a breakdown of the manufacturer’s weight limit to performance weight limit:
- 250 pounds to 163 pounds
- 300 pounds to 195 pounds
- 350 pounds to 228 pounds
- 400 pounds to 260 pounds
- 500 pounds to 325 pounds
If you are new to kayaks, all of these numbers and calculations might seem a bit strange to you. So let’s provide a real-world example.
Let us say you weigh 180 pounds and you typically carry about 30 pounds of supplies and gear with you, then you will optimally want a kayak that has enough capacity to carry all of your gear without sacrificing performance.
To find a kayak like that, you will have to take the combined weight of the supplies and yourself and divide it by 0.65 (the 65% performance weight ratio).
This would mean you need a kayak that has a manufacturer’s stated maximum weight limit of at least 323 pounds. Taking this example into consideration, you will discover that quite a bit of the kayak’s manufacturer’s weight limit capacity is sacrificed. This philosophy is something that most newbies to kayaks do not understand and that causes them to purchase a kayak with a completely inadequate maximum weight capacity.
While getting a kayak with a low kayak weight capacity is not ideal, there are a few things you can do to provide stability to the kayak. This can be done by installing a form of outrigger that increases stability and buoyancy. You could also place floatation bags in the stern and bow to increase floatation without increasing the bulk.
