Expert Fibreglass and Gelcoat Repairs for Yachts, Launches, and Multihulls

Work with us

Fibreglass is the backbone of modern boat construction, valued for its incredible strength, durability, and versatility. However, even the best built boats can suffer damage over time, whether from a minor marina mishap, a sudden grounding, general wear and tear, or the long-term effects of water ingress.

At Quayside Boatyard, we provide professional fibreglass repair services for monohulls, multihulls, and cruising yachts. Our focus is on restoring both the structural integrity and the original finish of your vessel. Whether you are dealing with a minor cosmetic scratch or a major structural project, our experienced team has the practical knowledge to assess the damage and deliver the right solution.

Fibreglass Repairs Done Properly

Not all fibreglass repairs are created equal. While surface damage can sometimes look straightforward, underlying structural issues can easily remain hidden beneath the gelcoat.

This is where our traditional boatbuilding background makes a real difference. Because we understand exactly how fibreglass vessels are engineered and put together, we do not just patch over a symptom. We identify the root cause of the structural issue and execute a repair that restores the boat's original strength. The result is a clean, long-lasting repair that protects both the safety of your crew and the long-term value of your vessel.
