Technical information

Weststream is committed to design and development. We have chosen to use the highest quality materials on the market and advanced manufacturing methods. In this way, we aim to offer you the highest quality inflatable rubber boats on the market.

Valmex® PVC 0.9mm, 1100 decitex

Valmex® comes from Mehler Texnologies of Germany. Mehler has been producing high quality PVC for over 60 years and is leading the way when it comes to materials for inflatable boats. Mehler works with the most advanced technology to ensure that Valmex® PVC is flexible, durable, resistant to abrasion, chemicals and UV. Valmex® has high adhesion and high air tightness. Mehler Texnologies is a pioneer in weldable fabrics for rubber boats. Made in Germany. Ideal for inflatable rubber boats.

Thermo welded seams

A thermo-welded seam is four times stronger than a glued seam. In addition, the seam will be stronger than the fabric itself, due to the creation of a mechanical bond rather than a chemical bond. It is important to remember that the seams of an inflatable boat are under constant pressure, and every time a glued seam is exposed to UV radiation, it becomes weaker. Our production is done with the latest technology, and we have chosen to use thermo-welded seams to ensure high quality and durability.

The reason why not all inflatable rubber boats have welded seams is that:

  1. Many PVC materials do not hold for welding
  2. It is a much more skilled manufacturing process
  3. The cost is higher

Rapid drain system

2 automatic self-bailing aluminum transoms. These are located at the bottom of the hull, one on the right and one on the left side of the transom. This means that even if the boat is slightly tilted, any water will drain directly from the boat. The higher position of the colander also prevents water from entering during normal handling. From a security point of view, this is an optimal solution. Whether you drive hard, leave the boat and it rains, the water runs out. Even when towing and if a wave breaks, the water drains out for maximum safety. In addition, this design makes it easy to clean the interior of the boat.

Transom in aluminum

We have carried out extensive tests on both closed and open transoms. By testing different materials such as marine plywood, fiberglass and tubular structures, we have concluded that for most users a closed transom is significantly more beneficial. Closed transoms provide a much more rigid and safe boat compared to open versions. At Weststream, our transoms are made of aluminum. Aluminum is a material that resists moisture, does not rust, and is both strong and light. In addition, our unique self-bailing system is positioned in the transom to empty the boat at lightning speed. The rigidity provided by our aluminum transoms also means that all the power from your outboard is effectively transferred to the water. In addition, a closed transom keeps your feet dry and ensures that your belongings remain safely on board!

The oars are easily placed in their annual toll

We have chosen to use a strong annual duty that meets tough requirements. This makes the boat easy to drive and therefore easy to row. Moreover, these holders are standard on all our boats. In other words, you can expect the same high quality and performance no matter which model you choose.

5 air chambers, incl. Floor

Our pontoons are separated in several air chambers for extra safety. Each tube has 2 chambers and the floor has one, a total of 5 separate air chambers. Should the accident occur, it is a great security that there are several tubes that have the air left. We use high quality valves with a pump position and a locking position.

Side protection / Spray protection

Solid rubber strips around the entire boat's tubes, protect your inflatable boat from abrasion from other boats, rocks and quays. The list also works as a spray protection from water splashes.

High pressure floor

High-pressure flooring made of dropstitch material consists of several hundred thousand nylon threads that hold the flooring together. This means that you can pump it hard (0.68bar / 9.8psi), it becomes light, stiff and stable. When the air tire is inflated to working pressure, it feels as hard as a hard floor, when it is emptied of air, you roll it up easily, which makes it easy to store.

Valmex® Diamond anti-slip protection on the entire floor

We have equipped all models with anti-slip protection from Valmex®, to provide a non-slip surface and extra abrasion protection on the floor. Nice, safe and protective at the same time.

Heavy Duty tube protection

Along the entire length of the tube, there is a strong tube guard that protects the tube from damage. Moreover, since a catamaran goes high in the water, it allows you to go closer to the shore or up the beach, cliff, etc. Therefore, it is good to have such protection to avoid damage and extend the life of the boat. Inflatable rubber boats with tube covers are perfect for adventure.


Three D-rings in the bow to be able to tow and most D-rings placed to be able to secure bags, cans etc. in the boat. Also the opportunity to hang in the davit.

Oar velcro holder inside

Most often you use your inflatable boat with an engine and then it is nice to be able to attach them inside the boat. 2 velcro locks per tube are available to attach the oars. Never go out on the lake without oars.

Toft of aluminum

To sit stably, all boats are equipped with a strong tuft of aluminum, it is attached to the two brackets on the tube. The boats can also be used without tuft as it is easy to remove.
