What We Do: From Fixes to Fabrication

Hull & Skin Repairs

When your hull is marred by impact, abrasion, blistering, or osmosis, we restore it to its original condition. Our technicians assess damage, remove compromised laminate, and rebuild with marine-grade fabrics and resins. The result is a restored shell that retains strength, integrity, and hydrodynamic fairness.

Gelcoat & Finishing

A structurally sound hull isn’t enough; aesthetics matter. We color-match and apply gelcoat with careful blending, sanding, and polishing to erase scars, match adjacent areas, and maintain a seamless finish. Whether patching stress cracks or dealing with cosmetic blemishes, we treat appearance as part of performance.

Custom Parts & Fabrication

Need a deck hatch, custom fairing, instrument pod, intake scoop, or ladder bracket? We produce custom fiberglass parts to spec. Using molds, plug patterns, or hand layup techniques, we ensure each part aligns with your vessel’s geometry, fits flush, and bonds reliably.

Thruster Tunnel & Bow Thruster Installs

Thruster tunnels demand precision. We cut, reinforce, and fit tunnels with accurate curvature, integrate with hull core and skins, and reinforce around openings. We also create flanged bolt-in mounting systems and custom fairings for seamless integration.

Composite Reinforcement & Overlays

We apply strengthened overlays — carbon, Kevlar, biaxial, or multiaxial fabrics — over areas that experience high stress, impact zones, wet exhaust cavities, or abrasion-prone regions. These overlays enhance durability without adding excessive weight.

How Pacific Fiberglass Delivers Value

At Pacific Fiberglass, we combine two essential elements that define quality marine repair—exceptional craftsmanship and rigorous structural discipline:

The Process You Can Expect from Pacific Fiberglass

  1. Damage diagnosis & mapping
    Using moisture meters, visual inspection and core samples when necessary, we precisely define the impacted area.

  2. Cut-out and preparation
    The damaged skin or core is selectively removed, the edges feathered, and the surfaces prepared for bonding.

  3. Layup & reinforcement
    We carefully rebuild the laminate stack, integrating core, reinforcements, and skin layers in sequence.

  4. Fairing, finishing & gelcoat
    After curing, we fair the surface and apply gelcoat, matching blends, color, and finish to the surrounding areas.

  5. Fit & integration of components
    For installations (like tunnels or pods), parts are trial-fitted, trimmed, bonded, and sealed.

  6. Final QA & sign-off
    We perform non-destructive checks, dimensional verifications, and ensure aesthetics meet high standards before release.

If you’re looking for a fiberglass specialist who can handle anything from a cracked hull panel to a new thruster tunnel or custom structural overlay, Pacific Fiberglass – Fiberglass Works is your partner. Let us bring precision, durability, and marine expertise to your next project.

Client Testimonials

“Kudos to Doug and his team for doing an amazing job! We had only scheduled Pacific Fiberglass to check the rudders, as we were planning on doing the rest of the work ourselves. After hauling out and realizing it was a bigger project than we could handle, they gave us a very reasonable quote, jumped on the job and we were out of the boatyard in 6 days! Amazing work! Thanks to your team!”

Scott Helfen

Client Testimonials

“I brought my sailboat in to Pacific Fiberglass for structural hull and stringer repair after a hard grounding and the work they completed was top-notch. They did all the coordination with Canal Boatyard for travel lift work and kept in good communication with me through the entire process, staying on schedule and on budget. My boat went back into the water better than ever and I couldn’t be happier. It’s nice to see a small business such as this be able to stay in business in Seattle. They would be my first choice for any future fiberglass work I might need done.”

Client Testimonials

“Doug and his team did me proud. I took my boat in for bottom paint and some other minor repairs. The weather wasn't cooperative so we had a couple minor delays. But once they completed the work, I was very happy. Under budget and done right. Robert especially was key, he kept me informed and up to speed on the job. I'm glad I decided to go with Pacific Fiberglass. Thanks guys.”
