When my glass guys stripped the "skin" off the transom of my 1997 268 Islander they took this picture for me. Rotated and blown up you can read "XL", "Lifetime Warranty", "quality audited".
Quick check with Google AI: This is "Greenwood XL" that GW used in 1997. Typical latent defect. Warranty only covers material - nothing else. GW will say it's not their fault. Material did not perform anywhere close to their specification. But don't worry...it's nothing that can't be fixed for about $12,000.


Greenwood XL marine plywood (often branded as XL or XL-50) features a specialized pressure-treatment and waterproof glue formulation designed to resist fungal decay, rot, and insects. It carries a manufacturer-backed limited lifetime or 50-year warranty against rot, though coverage typically applies only to replacement of the raw wood material and excludes fiberglass, epoxy, or labor costs.

Quality Audit & Performance
- Core Construction: Manufactured with void-free inner plies and weather-and-boil-proof (WBP) bonding agents to stop moisture infiltration from the inside out.
- Treatment Process: Uses a specialized pressure-treatment that alters the wood cell structure rather than standard off-the-shelf treatments, minimizing leaching.
- Field Longevity: Widely adopted by prominent boat and pontoon builders (such as Grady-White and Bennington) for transoms, stringers, and deck panels with high historical success.
Warranty Scope & Limitations
- What is Covered: Structural failure or fungal rot of the Greenwood XL plywood panel itself.
- What is Excluded: Labor, fiberglass delamination repair, gelcoat work, secondary hardware damage, or costs to tear down and reinstall the panel.
- Transferability: Varies by the original boat or vehicle manufacturer; some brands permit transfer to a second owner within a specific initial window (e.g., first 10 years), while the raw wood guarantee relies on the original Greenwood Forest Products specification guideline.
