Marine Fabrics vs. Standard Outdoor Fabrics: What’s the Difference?

For years, marine fabrics have been mistaken for regular outdoor textiles. But while outdoor fabrics are made to withstand occasional exposure to the elements, they aren’t built for the extreme, year-round conditions of marine environments.

Marine fabrics are engineered to endure relentless sun, salt, and moisture—the very factors that cause standard outdoor materials to break down. They do more than just look good; they protect your boat’s interior and provide long-term durability while maintaining a healthier onboard environment.

The Power of Indanthrone Dyes

Color durability is just as important as fabric durability when it comes to marine textiles. That’s why high-performance marine fabrics use Indanthrone dyes, a class of highly stable, fade-resistant pigments. These dyes offer key benefits that make them ideal for marine environments:

• UV Resistance – Maintains color vibrancy even under relentless sun exposure.
• Saltwater Durability – Withstands constant contact with salty air and seawater without fading or degrading.
• Weather Resilience – Holds up against extreme heat, humidity, and fluctuating temperatures.
• Non-Bleeding & Non-Degrading – Prevents color from washing out or transferring onto surfaces.
• Deep, Rich Color – Provides a lasting, high-quality finish that enhances the aesthetics of marine fabrics.

Unlike standard dyes that fade quickly, Indanthrone Blue ensures long-lasting color stability, making it an essential component of true marine-grade textiles.

Soledad One, Pero Marine, Hvar, Dalmatia, Kvarner and Kornati collection products are ALL Indanthrone.

Why?

Because this is the only way to go when it comes to marine environments.

And it is especially important for upholstery fabrics as they are meant to last and serve.

 

The Problem with Sponge Upholstery on Boats

In outdoor settings, many lounge chairs and seating sets are made with sponge fillings. Likewise, many boats still rely on traditional sponge-based upholstery. To protect it, some use laminated acrylic waterproof fabrics. While this prevents water absorption, it also traps heat, making the cushions unbearably hot in the sun—not to mention the added plastic, which is neither eco-friendly nor comfortable.

On land, this might not be a big deal—you can simply head inside and relax on your regular couch. But on a boat, that’s not an option. Your summer life happens in the cockpit, and if your cushions are rotten, damp, smelly, or dirty, they can ruin the entire experience.

In this setup, comfort is sacrificed just to keep the sponge intact. But does that really make sense?

You shouldn’t have to choose between comfort and durability. You deserve both.

To conclude - Why Sponge Isn’t Ideal for Boats?

Sponge upholstery might work on land, but on a boat, it’s a recipe for trouble. When exposed to moisture, sponge:

• Deteriorates over time
• Loses its shape
• Absorbs odors

There’s a better way.
