Soft Spots & Delamination Repaired to Solid.

A soft spot is a symptom, usually of water getting into the core through a fitting, crack or old repair, or of the skin letting go after an impact or years of flexing. We moisture-test and sound the area to map how far it runs, then remove the bad core and re-laminate from solid material to solid material.

Delamination is when layers of fiberglass separate from each other, so the hull no longer works as a single skin. It often sounds dull when tapped and can show up as cracking or bulging in the gelcoat. We cut away the separated layers back to a sound bond, lay up new structural glass, then fair and gelcoat to match.

Once water reaches a balsa or plywood core, it wicks outward every season and the wood starts to rot, losing its grip on fasteners and fittings. Injecting resin over wet core only traps the moisture, so we open one skin, remove all wet material back to dry edges, bond in new marine-grade core and re-laminate.

Sometimes the core is still intact but the fiberglass skin has let go of it, often after an impact, an old repair or years of flexing, and the panel loses its stiffness. Small, dry separations can sometimes be injected and locally re-bonded. Larger or wet areas are opened up, the core replaced, and the skin re-laminated to it.

The spot you can feel is rarely the whole problem, because water spreads through the core well beyond it. Before any cutting, we take moisture meter readings and tap the area with a hammer: dry, bonded laminate rings, while wet or separated laminate sounds dull. That map shows the true size of the repair before you commit to it.
