Inflatable boats come in a wide range of shapes, sizes, and types. But did you know they also come in a range of different materials?
These materials play a crucial role in your boat's performance and durability, and picking the right one will ultimately affect how you enjoy your time on the water.
Why Does Boat Material Matter?
If you're in the market for a new inflatable boat, several considerations will influence your choice of material, such as:
-
Durability
-
Weather resistance
-
Intended purpose (where you will sail your boat)
-
Cost
-
Availability
Each material offers unique advantages and disadvantages that you should weigh carefully, as choosing the wrong one could mean replacing your inflatable boat sooner than expected.
The 4 Different Types Of Boat Material
There are four key types of material used for inflatable boats:
1. TPU (thermo-polyurethane)
TPU is a rising star in the inflatable boat market thanks to its excellent balance of durability, weight, and longevity.
It's highly abrasion-resistant and doesn't suffer tears and punctures easily, making it a great choice if you like to take your boat out into rugged, rocky environments.
TPU is also highly weather resistant. It's better than PVC for UV resistance and remains flexible even when the temperature drops to freezing.
To increase the level of UV resistance, it's possible to treat TPU with UV inhibitors and prolong your boat's life.
TPU cost and availability
A TPU inflatable dinghy is generally more expensive than those made from traditional PVC, and you can expect to pay between 20% and 50% more for TPU models. On the plus side, TPU is cheaper than Hypalon.
While it's not yet as widely available as other materials, demand is growing for TPU boats.
For example, Takacat boats, including the Takacat LX series, are now available in TPU by special order.
Who should get a TPU inflatable boat?
TPU is a great choice if you like boating in harsh environments. Plus, its ability to withstand freezing temperatures offers an advantage to those living in colder climates.
Additionally, TPU is more environmentally friendly than PVC, making it ideal for eco-conscious boat enthusiasts.
2. PVC
PVC (Polyvinyl Chloride) is the most commonly used material for inflatable boats.
PVC is a lightweight material that offers moderate resistance to abrasions, scrapes, and punctures. However, prolonged exposure to UV rays and cold temperatures can lead to degradation, stiffness, and cracking.
A better alternative to standard PVC is Heytex 5509 PVC, which is what the inflatable tubes of our Minicat boats, such as the 420 and 460 models, are constructed from.
Heytex 5509 PVC is more durable, offers excellent air-retention properties, and superior UV and weather resistance. Manufactured in Germany, the material is held to strict quality control standards, making it an incredibly reliable alternative.
However, keep in mind that PVC is raising serious environmental concerns and is very hard to dispose of or recycle. As such, some countries and regions are starting to phase it out or ban it entirely.
PVC cost and availability
PVC boats are the cheapest and most widely available. For instance, our Minicat 310 Sport starts at $5,200, while the Minicat Guppy is $4,500.
But, when buying an inflatable boat, remember that PVC fabric may eventually be outlawed.

A PVC boat offers an affordable entry point into the world of inflatable sailing. It's a good choice for budget shoppers and occasional recreational use.
3. Hypalon
Hypalon fabric is a type of synthetic rubber material initially developed by DuPont in the 1950s.
Performing better than PVC, Hypalon boats offer excellent resistance to UV rays and can easily withstand harsh environmental conditions. Plus, the use of neoprene adds flexibility while maintaining air tightness.
Hypalon is also a better alternative to PVC for use in rigid inflatable boats.
However, Hypalon has a significant drawback: the boat's construction relies on glued rather than welded seams.
The adhesive does not perform well in hot temperatures, and some lakes prohibit the use of glued-seam boats. This is because the lakes are treated with high-temperature sprays to keep invasive species at bay and the heat will degrade glued seams.
Due to this flaw and environmental concerns, DuPont discontinued production of Hypalon in 2010, although a similar formula is still produced by other manufacturers.
Hypalon cost and availability
Hypalon is one of the most expensive materials for an inflatable boat. For instance, a small-sized dinghy will set you back around $2,000, while a rigid inflatable boat can cost as much as $20,000 or more, depending on its size and features.
Hypalon used to be widely available, but with DuPont discontinuing production, it's becoming harder and harder to find. You may have an easier time finding a Hypalon model on the pre-owned market.
Who should get a Hypalon boat?
Given its durable nature, frequent users and coastal boaters should consider Hypalon. However, lake boaters should probably avoid it.
Hypalon's temperature resistance means it's also great for those living in cold climates.
4. Vulcanized Rubber
Used in our Happy Cat boat range and Grabner Canoes and Kayaks, vulcanized rubber consists of a combination of synthetic and natural rubber that has been pressure-heated.
The result is an inflatable boat with incredible elasticity, strength, and resistance to environmental factors without suffering degradation, including damage from UV light and a wide temperature range. This toughness and high abrasion resistance contribute to its long lifespan.
Furthermore, given its use of natural materials, vulcanized rubber can be considered a more environmentally friendly option.
Vulcanized rubber inflatable boat cost and availability
Vulcanized rubber boats are widely available from notable manufacturers such as Grabner.
At a higher price than TPU or PVC, the payback is enhanced quality and performance. For instance, the Happy Cat sailboat range starts at $9,500 and goes up to $17,995 for its carbon models.
Who should get a vulcanized inflatable boat?
Anyone with high-performance needs should consider a vulcanized rubber inflatable boat. It's suitable for recreational boating but can also withstand the heavy use of adventure sailing.
However, given that the material is slightly heavier and much more expensive than other materials. These boats are an investment into a hyper durable and reliable boat that will last decades.
Which Boat Material Lasts The Longest?
A popular myth is that a Hypalon boat will last forever, while PVC boats are only good for a season or two.
While Hypalon and vulcanized boats last a long time, like any other boat, they have a limited lifespan. Similarly, PVC can last for over a decade if well-maintained.
Here's how long you should expect your boat to last:
-
TPU: 5 - 15 years
-
PVC: 5 - 10 years
-
Hypalon: 15 - 20 years
-
Vulcanized rubber: 20+ years
How Is The Market Evolving?
As the inflatable boat market evolves, we can expect to see PVC phased out in favor of more sustainable alternatives.
We will also see the increased use of nanocoatings and hybrid fabrics (like TPU) to improve weather and abrasion resistance. Self-healing materials and modular designs are also exciting advancements that will extend the life of inflatable boats.
How To Clean And Maintain Your Inflatable Boat
Each type of inflatable boat requires careful cleaning and maintenance to keep your boat in good shape:
-
Clean regularly: After each use, especially after using it in saltwater, take a soft brush and scrub gently to get your boat clean. Then, rinse it with fresh water and let it air dry before storing.
-
Use mild detergent: Inflatable boats do not like harsh chemicals. Only use mild soap solutions or specialized cleaners when removing dirt.
-
Apply UV protectant: This isn't essential, but applying a protectant will prolong the lifespan of your inflatable boat.
-
Store properly: To prevent mold and mildew, the boat must be dry before folding and packing. Store away from direct sunlight and heat sources.
-
Inspect: Regularly check your boat for punctures, seam tears, and other signs of wear. Repair your boat as needed.
