My name is Jeroen Van der Knijff, since 1998 I have been active in the Dutch maritime sector. Throughout these years, I have explored many facets of the water sports world, with a special interest in repairing damages to polyester vessels, plastic, and composite objects.
SPECIALIZATION AND EXPERIENCE
Since 1998, I have increasingly specialized in damage repair, initially mainly on-site and later also in my own workshop for larger projects. My expertise includes not only fiberglass but also carbon fiber. In the early years of my career, I learned a lot about building carbon sandwich constructions and using vacuum and infusion techniques. Among other things, I have worked in the high-end windsurfing industry and with Nacra Sailing on the foiling Nacra17, the current Olympic catamaran.
From 2002 to around 2021, I worked intensively with the importer of Corsair Marine benelux (Jan de Boer Catamarans) where I gained extensive experience with models such as the F24, F27, F28, and F31 (sandwich composite construction). During this period, I assembled dozens of new boats and repaired countless damages, both structurally and cosmetically.
Over the past 10 years, I have further specialized in gelcoat repairs. This outer layer of a boat, which is difficult to repair and color match, can in most cases be invisibly repaired thanks to my extensive experience.
A NEW CHAPTER IN SPAIN
In 2026, I will also start new chapter on the Spanish coast. Here, on the Costa Blanca, the expertise and experience I have gained in the Netherlands will also be brought to Spain to offer the same high-quality service.
With "Fiberfix.es," I am ready to help customers with all their polyester and composite repair needs, with the same dedication and craftsmanship that my customers in the Netherlands and around the world can expect from me.
