Why Dinghy Repair is a Skill Every Boater Should Master
Owning an inflatable dinghy opens up a world of marine adventure, but like any dependable vessel, it's only as reliable as the care you give it. Whether you're a recreational paddler, an offshore angler, or someone who uses their True Kit inflatable boat as a yacht tender, knowing how to perform basic repairs is a great skill. With regular use comes inevitable wear and tear, minor leaks, abrasions, and valve issues can all be managed swiftly with the right knowledge.
Learning the art of inflatable dinghy repair isn't just about saving money, though it certainly helps. It's about confidence and self-reliance on the water. If you're a proud owner of a True Kit inflatable boat, you're already equipped with a premium craft engineered for performance and durability.
Signs of Dinghy Damage and How to Spot Them
Understanding the root causes of damage is the first step toward proper inflatable dinghy repair. Common culprits include UV degradation, sharp rocks or coral, improper storage, and overinflation. While True Kit boats are constructed with premium materials like Valmex® fabric and thermo-welded seams, no inflatable is completely immune to environmental stress and misuse.
Regular inspections are always recommended. Before every outing, check for any visible damage.
How to Locate and Identify Air Leaks in Your Inflatable Dinghy
Detecting air leaks is a simple but essential diagnostic task. Here is an informative video outlining our recommendations.
- Start by inflating your boat to full pressure
- Ensure the boat is clean
- Sometimes large leaks can make a hissing sound. If you can’t hear a leak, mix a small batch of soapy water and spray it on suspect areas (the valves are a great place to start). Bubbling foam indicates escaping air. Remember - if you cant find the leak to start, patience is key. Go from section to section ensuring the soapy water create a thin film over the entire surface.
Mark any trouble spots clearly with a marker or tape so you can easily locate them when it’s time to patch.
Essential Tools and Repair materials for a Inflatable Boat Repair
Before you can tackle repairs confidently, you’ll need to ensure you have all the appropriate materials and tools. At a minimum, your inflatable dinghy repair kit should include temporary adhesive glue, repair patches, and a valve wrench.
Glue & Prep:
For permanent repairs we recommend sourcing the correct glue locally. For True Kit boats, this is a two pot heat-activated PVC glue. In the True Kit workshop we use Bostik Unigrip 999 and the desmodur hardener. Ensure to follow the instructions on your specific brands product.
A solvent is required to clean and prepare the surfaces. We use Bostik number 4. However, you can use other products like MEK or Acetone. (Methylated spirits can be used if you have no other option).
Fabric:
Ensure you have the correct fabric for the repair. Reach out to the boats Manufacturer if you don't have any spare fabric.
Tools:
- Heat Gun (or hair dryer)
- Masking Tape
- PPE (Gloves & Mask)
- Scissors or Stanley Knife (Cutting the patch to size)
- Pen
- Brush (for application)
- Rag (for solvent application)
DIY Inflatable Boat Repair for Small Tears, Punctures, and Seam Issues
- Once you’ve identified the leak, you need to properly prepare.
- Before doing anything on you boat you need to make sure your boat or at least the effected area is clean. You can do this by simply washing your boat down with soapy water, make sure your boat is completely dry before proceeding.
- Cut a patch so it's at least 20mm from the leak point on all sides. Round the corners to prevent peeling.
- Place the patch over the leak where you want it positioned and trace with a pen
- Apply the masking tape - following the lines. Depending on the size of the leak you can deflate your boat now to make masking easier.
- Avoid touching the area - clean both the patch and leak with solvent.
- Prepare the glue following the manufacturers instructions.
- Using the brush apply the glue to the patch and affected area (ENSURE THE CHAMBER HAS NO PRESSURE & IS COMPLETELY DEFLATED).
- Wait for the glue to tack off - usually around 5-10 minutes then rip the masking tape off.
- Apply heat to the patch and affected area, then carefully place the patch in position. Apply constant pressure. You can then apply more heat if you think it's necessary (Too much heat can damage the fabric).
- Let the patch set for at least 24 hours before inflating.

How to repair a large tear on your inflatable boat
Seam Issue Repair
For seam separation, follow the same steps, using extra care to align the surfaces properly.
Seams are often the Achilles' heel of most inflatable boats, but not with the True Kit range. We thermo-weld all of our seams, creating a bond that is stronger than the fabric itself. Don’t settle for glued seams.
Valve Repair and Replacement
Slow leaks can often be traced back to faulty valves. With repeated inflation/deflation cycles, sand or salt can compromise the seal. First, check for debris around and in the valve. Sometimes a spray of a lubricant like CRC fixes a sticky valve. If the valve appears loose, tighten it using a compatible valve wrench.
If the chamber is still losing pressure after tightening, spray with soapy water to confirm its the valve. You may need to reseal or replace the valve entirely. Most valves unscrew with two-part components. After removal, clean the threads, inspect, and reinstall with a bit of heat. For True Kit inflatable boats, OEM valve systems ensure performance and reliability, so match components when sourcing replacements.
Please watch this video for an in-depth review on how valves work and how to replace them.
When to DIY vs. Professional Boat Repair Services
DIY repairs can work well for small issues such as minor punctures, slow leaks, or cosmetic scuffs. However, more complex damage — including delaminated seams, deep gashes, or transom failure — should always be handled by a professional. Attempting these types of repairs without the right experience and equipment could compromise both the safety and performance of your boat.
As a rule of thumb: if the damage compromises a load-bearing structure, is larger than a dollar bill, or affects the floor or keel inflation chambers, it’s best to have it assessed by a professional. Certified inflatable boat repair shops use industrial-grade tools and processes that most DIYers simply don’t have access to.For True Kit owners, deferring to a professional when needed is also important to protect your warranty. Contact us if you have any questions about issues or warranty.
Inflatable Dinghy Maintenance Tips
Regular maintenance doesn’t just prolong life, it preserves performance. Always rinse your dinghy with fresh water after each use, especially in saltwater environments. Dry it completely before storing to prevent mold or mildew.
Check inflation levels periodically, and avoid storing the boat in extreme temperatures. Don’t stack heavy items on top. Apply Protectant or a similar UV guard for extra protection.
For seasonal checkups, inspect seams, valves, and accessories like the bimini or rod holders. Make sure mounts are still sealed and functional. True Kit’s resources section has more tips and expert care guides.
Smart Accessories to Reduce Wear & Tear on Inflatable Dinghy
Accessories don’t just add convenience, they can extend your boat’s lifespan. Launching wheels are a great example of this. Avoid dragging the boat and invest in quality wheels for ease and protection.
True Kit’s accessories collection includes high-durability upgrades like the Permatrim performance foil to reduce cavitation, or premium seat bags that double as storage and reinforcement. Lightweight options like the Railblaza rod holder integrate seamlessly with fishing setups.
Keep Your Adventures Afloat With Confidence and Know-How
Whether you're launching from a pristine shoreline or using your inflatable as a tender in rugged marinas, knowing how to execute and prevent repairs is a great skill. Even with the durability of a True Kit inflatable boat, nature, and usage will eventually leave their mark. But with the right tools and know-how, you're never more than a couple days away from getting back on the water.
