Coosa® and ATL Composites’ Role in Australia’s Composite Evolution
Across modern boatbuilding and structural composite construction, the shift away from traditional timber cores is accelerating — driven by performance demands, lifecycle durability, and weight reduction.
At the centre of that evolution sits Coosa® Composite Board, globally recognised for its high-performance structural panels. In Australia, that technology is supplied and supported by ATL Composites, the authorised distributor of Coosa®.
For more than a decade, ATL has worked closely with boatbuilders, refit yards, and composite fabricators to integrate Coosa® Bluewater into next-generation marine structures — replacing plywood with advanced composite alternatives engineered for longevity.
Engineering a Better Core
Manufactured by Coosa Composites in the United States, Bluewater panels are
constructed from high-density, closed-cell polyurethane foam reinforced with
continuous and woven fibreglass.
The result is a structural panel that delivers exceptional durability while achieving significant weight reduction — typically 30 to 50 percent lighter than plywood.
This weight saving translates directly into performance advantages on the water, improving vessel efficiency, speed, and payload capacity, while reducing fuel consumption over the vessel’s operational life.
Equally critical is Bluewater’s resistance to water ingress.
Unlike timber cores, the composite structure will not rot, swell, delaminate, or absorb moisture — eliminating one of the most common causes of long-term structural degradation in marine builds.
As Jay Arnold, VP Sales & Marketing at Coosa Composites, explains:
“Coosa panels comprise two main components — polyurethane and fibreglass. Together, these make the panels lightweight, strong, and water resistant.”
Leadership Driving Global Expansion
Arnold joined Coosa Composites four years ago, bringing with him a strong background in sales and marketing across the sporting goods, golf, and field sports sectors.
His appointment signaled a strategic push into new international markets and applications beyond the company’s traditional marine stronghold.
Today, Arnold is charged with leading Coosa through its next phase of global growth and product innovation — expanding distribution partnerships and developing new industry adoption pathways.
Though Coosa may cost slightly more upfront, the long-term savings can be exceptional, Arnold notes. “In marine environments, the no-rot feature means customers don’t need to worry about replacement or rebuild”.
Expanding Beyond Marine
While boatbuilding remains Coosa’s largest and most established market, demand for composite structural panels is accelerating across new sectors globally. Growth areas include:
- Transportation flooring and structures
- Recreational and specialty vehicle builds
- Modular and mobile infrastructure
- Industrial structural components
- Custom architectural projects
These industries are increasingly specifying composite cores where weight, durability, and moisture resistance are critical performance requirements.
Arnold points to flooring as one of the fastest-growing applications, particularly in mobile environments where structural integrity must be maintained under constant load and exposure.
Why Bluewater Leads in Marine
Within the Coosa portfolio, Bluewater remains the premium structural specification for high-load marine construction.
Its additional woven fibreglass reinforcement provides:
- Enhanced compressive strength
- Improved screw retention
- Greater stiffness
- Higher impact resistance
This makes it ideal for structural components such as transoms, stringers, bulkheads, decks, and engine beds — areas where long-term reliability is critical.
Builders also benefit from ease of fabrication.
“The ease of cutting and shaping the material with traditional woodworking tools makes switching to Coosa an easy choice,” Arnold adds.
The ATL Role — Local Supply, Technical Integration
As Australian distributor, ATL Composites plays a key role in supporting Coosa’s growth within the region.
Beyond supply, ATL provides:
- Local stockholding and warehousing
- Reduced lead times
- Technical guidance
- Composite system integration support
Bluewater panels are frequently specified alongside ATL’s broader composite material systems — including laminating resins, structural adhesives, and reinforcement fabrics — ensuring full laminate compatibility and structural performance.
This integrated approach reflects ATL’s broader value proposition: delivering lightweight, high-performance composite systems engineered for durability, precision, and reliability.
A Material Aligned with Modern Build Philosophy
As global industries continue shifting toward lightweight engineering and corrosion resistant materials, composite core technologies like Coosa Bluewater are transitioning from alternative option to design standard.
For boatbuilders and composite engineers alike, the benefits are measurable:
- Weight reduction
- Maintenance elimination
- Lifecycle cost savings
- Structural longevity
Through its partnership with Coosa Composites, ATL continues to bring these globally proven material technologies to the Australian market — supporting builders as they transition toward the next generation of composite construction.
