Choosing the best fabric for a boat cover is about more than picking a colour or finding the cheapest option. The right material needs to protect your boat from Australian sun, rain, moisture, salt, dust and the stresses of towing.
A high-quality boat cover should balance UV resistance, water resistance, breathability, durability, colour retention and strength. The right choice can help protect your boat and extend the useful life of the cover.
“For Australian boat owners, investing in a purpose-built marine-grade boat cover fabric is particularly important because covers may face intense sunlight, changing weather and regular road travel.”
What Is the Best Fabric for a Boat Cover?
There isn't one fabric that is perfect for every boat or application.
The best boat cover material depends on:
- Whether the boat is stored indoors or outdoors
- How often it is towed
- Exposure to Australian UV
- Rain and moisture levels
- Saltwater exposure
- Required breathability
- Boat size and configuration
- Whether the cover is designed for towing or storage
For premium marine applications, solution-dyed and UV-stabilised marine fabrics are commonly selected because they are designed for demanding outdoor conditions.
Covercraft uses premium marine-grade fabrics including Sunbrella and Recacril, selected for marine and outdoor applications.

7 Things to Look for in Boat Cover Fabric
1. UV Resistance
Australian sunlight can be particularly harsh on outdoor fabrics.
Your boat cover should help protect the boat from prolonged sun exposure while resisting fading and material degradation.
Look for fabric with:
- UV resistance
- UV stabilisation
- Good colour retention
- Outdoor durability
This is particularly important if your boat spends long periods outside.
Covercraft's marine fabrics are UV stabilised and designed for outdoor and marine environments.
2. Water Resistance
A boat cover needs to deal with rain and moisture effectively.
However, choosing a fabric simply because it is described as "waterproof" isn't enough.
A good marine cover should also manage moisture and condensation appropriately.
The goal is to keep external water away from the boat while allowing trapped moisture to escape.
The best boat cover fabric should provide strong water resistance while still allowing appropriate breathability.
This balance is particularly important for boats stored outdoors for extended periods.
3. Breathability
Breathability is one of the most overlooked factors when choosing a boat cover.
A completely sealed cover can potentially trap moisture underneath, particularly when temperature and humidity change.
Breathable marine fabrics allow airflow and help reduce moisture build-up.
This can help minimise the conditions that contribute to:
- Condensation
- Mould
- Mildew
- Musty odours
- Moisture-related interior issues
Covercraft specifically highlights breathable fabric construction as part of its marine material technology.
4. Tear and Abrasion Resistance
If you tow your boat regularly, fabric strength becomes even more important.
During towing, the cover can experience:
- Wind pressure
- Road vibration
- Repeated movement
- Highway speeds
- Environmental debris
A fabric that performs well in stationary storage may not necessarily be the right choice for frequent towing.
For a boat travel cover, prioritise durable marine-grade fabric combined with secure fastening and a precision fit.
Covercraft's travel covers are developed using model-specific patterns and marine-grade materials for towing and storage applications.
5. Colour and Fade Resistance
A boat cover is exposed to the same environment as your boat.
Over time, low-quality fabric can fade or lose its appearance.
Solution-dyed fabrics are designed so colour is incorporated into the fibres rather than relying only on a surface coating.
This can provide better long-term colour retention in demanding outdoor environments.
Covercraft states that its solution-dyed fabrics, including Sunbrella materials, are designed to help maintain colour and performance over time.
6. Fabric Weight Isn't Everything
A common mistake is assuming:
"The heavier the fabric, the better the boat cover."
Not necessarily.
A good boat cover needs the right combination of strength, flexibility, breathability, UV resistance and durability.
An excessively heavy material may add unnecessary weight, while a lightweight fabric may not provide sufficient durability for demanding towing conditions.
7. Match the Fabric to How You Use Your Boat
This is perhaps the most important consideration.
For outdoor storage
Prioritise:
- UV resistance
- Water resistance
- Breathability
- Fade resistance
- Long-term durability
For regular towing
Prioritise:
- Tear resistance
- Strong stitching
- Secure fastening
- Model-specific fit
- Durable marine-grade fabric
For long-term marine exposure
Consider:
- UV resistance
- Moisture management
- Breathability
- Salt exposure
- Durable construction
For premium custom protection
Look for:
Marine-grade fabric + precision fit + quality stitching + appropriate fastening system.
Marine-Grade Fabric vs Cheap Outdoor Fabric
| Feature | Marine-Grade Fabric | Basic Outdoor Fabric |
|---|---|---|
| UV resistance | Designed for marine/outdoor use | Varies |
| Water resistance | Designed for weather exposure | Varies |
| Breathability | Available in purpose-built marine fabrics | May be limited |
| Colour retention | Better-performing options available | Can vary significantly |
| Towing suitability | Suitable fabrics available for travel covers | Not always suitable |
| Long-term marine use | Designed for demanding environments | May deteriorate sooner |
| Custom applications | Excellent | Limited depending on fabric |
The key point: Don't choose a boat cover based on price or fabric thickness alone. Choose the material according to where your boat is stored, how often you tow it and the level of protection you expect.
What Fabric Does Covercraft Use?
Covercraft uses premium marine-grade fabrics from trusted manufacturers including Sunbrella and Recacril for its boat covers.
These fabrics are selected for outdoor and marine applications and are designed to provide protection against sun exposure, rain, moisture and everyday environmental conditions.
Covercraft also manufactures its covers at its Bayswater, Victoria workshop, combining marine-grade materials with pattern development, CAD technology and experienced marine trimming.
This combination matters because premium fabric alone does not create a premium boat cover.
The fabric, pattern, stitching, fastening system and final fit all contribute to the finished product.
Why Fabric and Fit Should Be Considered Together
Even the best boat cover fabric cannot perform properly if the cover doesn't fit your boat correctly.
A loose or poorly fitted cover can:
- Move during towing
- Create unnecessary fabric movement
- Allow gaps
- Increase wear
- Reduce overall protection
Covercraft develops model-specific patterns to provide a secure fit across different boat models and configurations.
Even the best boat cover fabric cannot perform properly if the cover doesn't fit your boat correctly. For boats requiring a precision-fit solution, explore custom boat covers designed for your boat
Is an Expensive Boat Cover Fabric Worth It?
If you use your boat regularly or store it outdoors, investing in better-quality marine fabric can be worthwhile.
A premium cover can help reduce exposure to:
- UV damage
- Rain and moisture
- Dirt
- Salt
- Environmental debris
- Premature wear
