Boat Cover Material Showdown: 7oz vs 9oz vs Sunbrella

Choosing the Right Fabric for Your LaPorte Products Boat Cover

At LaPorte Products, we understand that choosing the right material for your boat cover is just as important as the craftsmanship behind it. Your cover isn’t just a piece of fabric — it’s protection for your investment, your time on the water, and the memories you make there.

We offer three trusted fabric options: 7oz, 9oz, and Sunbrella. Each one provides a unique balance of strength, appearance, and longevity, so you can select the perfect fit for your needs and boating lifestyle.

 

1. 7oz: Lightweight, Reliable Protection

Our 7oz solution-dyed polyester is a durable, everyday option designed for easy handling and dependable protection. The solution-dyed fibers mean the color runs all the way through the fabric — offering superior fade resistance compared to traditional surface-dyed materials.

This lightweight material is easy to install, remove, and store, making it a great choice for boaters who want practical coverage with a sleek look.

If you store your boat in a covered area or want a simple, protective option that looks sharp and performs well, the 7oz cover is an excellent value.

 

 

2. 9oz Solution-Dyed Polyester: Built for the Long Haul

For added strength and long-term performance, our 9oz solution-dyed polyester steps up the protection. This heavier-weight fabric is ideal for boats stored outdoors or in high-exposure environments, offering exceptional resistance to UV rays, moisture, and mildew.

It’s a customer favorite for good reason — it’s durable, breathable, and holds its shape beautifully over time. When properly cared for, many of our customers have enjoyed their 9oz covers for over 10 years, far exceeding the standard warranty period.

If you’re looking for a hardworking, long-lasting cover that can withstand year-round use, the 9oz polyester delivers the best balance of performance and value.

 

 

 

3. Sunbrella Solution-Dyed Acrylic: Premium Marine Performance

When only the best will do, Sunbrella is the ultimate choice. Known throughout the marine industry for its unbeatable fade resistance, breathability, and luxurious feel, Sunbrella is made from solution-dyed acrylic fibers that are designed to perform beautifully in harsh marine conditions.

This fabric resists UV degradation, mold, and mildew, while remaining soft and flexible. It’s ideal for those who want a premium look and maximum longevity from their cover.

Sunbrella combines performance and style — protecting your boat while maintaining its refined appearance year after year.

 

 

At LaPorte Products, our mission is simple: to help boaters protect what they love. Whether you choose the reliable 7oz, the proven 9oz workhorse, or the premium Sunbrella, every cover is backed by expert craftsmanship and the highest-quality marine-grade materials.
