• Reduce flexibility
• Accelerate ageing
• Weaken seams

UV exposure is one of the biggest threats to inflatable boat longevity.

Saltwater

Salt is highly corrosive and can affect:

• Valves
• Fasteners
• D-rings
• Oar locks
• Accessories
• Adhesive joints

Even if the inflatable material itself remains unaffected, associated components may deteriorate.

Dirt and Sand

Sand and dirt particles can create abrasion that gradually wears away protective surfaces.

These materials can also become trapped in folds and seams.

Moisture

Improper drying can lead to:

• Mould growth
• Mildew
• Odours
• Staining

Moisture management is essential for long-term storage.

Cleaning Your Inflatable Boat Properly

Cleaning is the foundation of inflatable boat maintenance.

A simple cleaning routine after each trip helps prevent many common issues.

• Organic material

Allowing contaminants to remain on the surface can gradually damage materials.

Cleaning After Every Use

After each outing:

Step 1: Rinse Thoroughly

Use fresh water to rinse:

• Tubes
• Floor
• Seats
• Oars
• Valves
• Transom

Pay special attention to areas exposed to saltwater.

Removing salt immediately is one of the most effective maintenance practices.

Step 2: Wash with Mild Soap

• Bird droppings
• Dust

If a cover isn't available, seek shaded storage whenever possible.

Avoid Constant Outdoor Exposure

Leaving an inflatable boat exposed year-round can significantly reduce lifespan.

Whenever practical:

• Store indoors
• Use covered storage
• Keep the boat shaded

Reducing UV exposure can add years to the life of your boat.

Proper Storage for Inflatable Boats

Storage practices have a major impact on longevity.

Improper storage can create avoidable damage even when the boat isn't being used.

Short-Term Storage

For short periods between outings:

Store Partially Inflated

If space allows:

• Keep the boat slightly inflated
• Avoid sharp folds
• Maintain shape

This reduces stress on the material.

Keep It Clean

Never store a dirty boat.

Salt, moisture, and dirt continue causing damage during storage.

Protect from Weather

Store in:

• Garage
• Shed
• Covered area
• Boat storage facility

Avoid direct exposure whenever possible.

Long-Term Storage

If the boat won't be used for weeks or months:
