Change or Repair a Semi-Rigid Tube: Costs and Methods
The inflatable tubes of RIBs (Rigid Inflatable Boats) are essential components ensuring the buoyancy, stability, and performance of the boat.
However, over time, these tubes can wear out or sustain more or less serious damage.
For boaters, a crucial question then arises: should the tubes be repaired or replaced?
In this article, Orca Retail helps you see things more clearly by addressing the causes of wear, common risks, repair and replacement methods, and their respective costs.
Lifespan and wear of inflatable tubes
The lifespan of a RIB's inflatable tube is generally between 5 and 10 years, depending on several factors.
Usage, maintenance, and environment all play a crucial role in the longevity of the tubes.
For example, use in saltwater, without adequate cleaning after each outing, can significantly reduce the lifespan of a tube.
Similarly, exposure to UV rays can also accelerate the degradation of materials, especially for PVC tubes.
Regular maintenance, such as washing with fresh water and periodic inspection for potential signs of wear, is essential to prolong the lifespan of your inflatable tubes and achieve long-term savings.
During periods of heavy use, it is advised to check the tubes monthly, especially as the high season approaches. Regularly assessing the condition of the tubes helps avoid costly repairs or, worse, premature replacement.

Frequent risks and accidents affecting RIB tubes
RIB tubes are often exposed to various risks that can cause damage. Navigation accidents, such as collisions with floating objects or groundings, represent one of the main causes of damage.
Moreover, during launching or storage, friction with rough surfaces can cause holes or tears.
Young children or pets on board can also accidentally damage the tubes by pulling on them or playing with them.
Besides physical accidents, weather conditions can also be detrimental. Extreme heat, frost, or prolonged exposure to bad weather can affect the structure of the tubes, making them more fragile.
Finally, chemicals such as gasoline, engine oil, or certain cleaners can deteriorate the materials.
Knowing these risks allows for the prevention of incidents and, if necessary, quick action for repairs.

Change or repair? Solving the dilemma
When faced with a damaged tube, the question of complete replacement or repair often arises.
To determine the best option, it is essential to assess the extent of the damage.
Small punctures or leak detections can generally be repaired.
However, if the tear is significant or if the material is too worn, replacing the tube may become the best solution.
This decision must also take into account the cost of repair compared to the price of a new tube.
Repairing a semi-rigid often remains the most economical solution to extend its lifespan.
For a simple repair, such as a small hole or tear, expect to budget between 50 and 100 euros for labor depending on the complexity of the intervention, and between 100 and 150 € per linear meter of Hypalon repair fabric.
On the other hand, completely replacing a float requires a much more substantial budget.
Choosing a new tube in PVC:
- Price range: from 2,000 to 10,000 € depending on size (from 3.5 to 12 meters)
- Lifespan: between 8 and 12 years
Choosing a new tube in Hypalon:
- Price range: from 4,500 to 20,000 € depending on size (from 3.5 to 12 meters)
- Lifespan: between 20 and 30 years
Opting for Hypalon represents an additional cost compared to PVC, but it is primarily an investment for the future, as this material is far more resistant.

Method of replacing semi-rigid tubes
Replacing an inflatable tube requires precision and expertise. Here are the key steps to perform this operation:
Step 1: Removal of old tubes
-
Completely deflate the tubes.
-
Remove the fixings and gently peel off the used tubes from the hull. A specific solvent may be necessary to remove glue residues.
Step 2: Preparing the hull
-
Thoroughly clean the surface where the new tubes will be attached.
-
Ensure that there is no residue of old glue or impurities left.
Step 3: Positioning the new tubes
-
Place the new tubes on the hull to check the alignment.
-
Mark the attachment areas for precise positioning.
Step 4: Applying the glue
-
Apply a specific glue for Hypalon or PVC, depending on the material of the tubes, on the hull and on the new tubes.
-
Let it dry according to the manufacturer's recommendations.
Step 5: Fixing the tubes
-
Attach the tubes to the hull by pressing firmly to ensure optimal adhesion.
-
Use a roller to remove air bubbles and enhance adhesion.
Step 6: Drying and checking
-
Let it dry for 48 hours before inflating the tubes.
-
Check the watertightness and ensure that the tubes are properly fixed.
Repair method for tubes with Hypalon fabric
To effectively repair inflatable tubes made of Hypalon, follow these steps:
Step 1: Surface preparation
-
Thoroughly clean the damaged area with fresh water and a mild detergent.
-
Dry completely and lightly sand the surface with fine sandpaper.
Step 2: Cutting the Hypalon fabric
-
Cut a piece of Hypalon fabric in a circular or oval shape, larger than the tear.
Step 3: Applying the glue
-
Apply special Hypalon glue to the piece and the area to be repaired.
-
Let it dry for a few minutes.
Step 4: Assembly
-
Firmly press the fabric piece onto the damaged area.
-
Use a roller to remove air bubbles.
Step 5: Drying time
-
Let the repair dry for at least 24 hours before reinflating.

Conclusion
In summary, the choice between changing or repairing a tube of a semi-rigid depends on the condition of the floats and the severity of the damage.
Sometimes, a simple repair can extend the life of the tubes, while being more economical.
However, when the safety and integrity of your boat are at stake, do not overlook the importance of making the right decision!
