Compare Coosa Board Options
| Feature | Bluewater 20 | Bluewater 26 |
|---|---|---|
| Density | Approx. 20 lb/ft³ | Approx. 26 lb/ft³ |
| Weight | Lighter option | Heavier, higher density |
| Structural performance | Strong lightweight structural panel | Higher strength and rigidity for demanding applications |
| Best suited for | General marine construction, panels, cabinetry, deck cores | Transoms, highly loaded structures, premium marine and industrial parts |
| Water resistance | Excellent | Excellent |
| Rot resistance | Yes | Yes |
| CNC machinable | Yes | Yes |
| Typical choice | When low weight is a priority | When higher strength and stiffness are required |
Bluewater 20 is generally chosen where reduced weight matters, while Bluewater 26 is better suited to applications requiring increased density, stiffness and load carrying performance.
| Feature | Coosa Board | Marine Plywood |
|---|---|---|
| Rot resistance | Yes | No |
| Water absorption | Very low | Higher |
| Weight | Significantly lighter | Heavier |
| Mold resistance | Yes | No |
| Dimensional stability | Excellent | Can warp or swell |
| Core material | Closed cell polyurethane reinforced with fibreglass | Timber veneer construction |
| Suitability for wet environments | Excellent | More vulnerable over time |
| CNC machining | Suitable | Suitable |
Coosa Board is commonly selected as a marine plywood alternative where reduced weight, moisture resistance and long term durability are important.
