Marstrom Composite AB

Active: 1982 – Present


As a beacon of innovation and precision in the world of marine composites, Marstrom Composite AB has carved out a distinctive niche, revered by yachtsmen and industry professionals alike. From its roots in competitive sailing to its current standing as a multidisciplinary composite expert, the Swedish builder embodies a relentless pursuit of lightweight strength and cutting-edge technology.

Marstrom Composite AB was founded in 1982 by Göran Marstrom. A formidable figure in the sailing world, Göran Marstrom secured a bronze medal at the 1980 Olympic Games, competing in the Tornado catamaran class. His firsthand experience as an elite sailor fueled a clear vision: a profound dissatisfaction with the existing Tornado catamarans spurred him to build something better. This drive for superior performance and construction laid the groundwork for Marstrom Composite, initially focusing on improving the very boats that defined his competitive career.

History and Evolution

The company's journey is marked by a steady evolution from a specialized boat builder to a leading composites manufacturer. While initially focused on Tornado catamarans, a significant milestone occurred in 1992 with the pioneering production of carbon fibre spars, establishing Marstrom as an early adopter and innovator in autoclaved composite technology. This expertise in high-quality carbon fibre products quickly became a hallmark of the company. By 1996, their reputation for advanced spar construction led them to build a spar for a 73-foot ULDB (Ultra Light Displacement Boat) designed by Pelle Peterson, a testament to their growing influence in performance yachting.

Over the decades, Marstrom Composite's proficiency in lightweight composite constructions expanded far beyond the marine sector. They diversified into other demanding industries, applying their expertise to aerospace, automotive, defense, and general industrial applications. This inter-industry knowledge exchange has undoubtedly enriched their marine offerings. More recently, Marstrom Composite AB has become a subsidiary of Scandinavian Astor Group AB, further solidifying its position in the market. The company continues to expand its marine operations, signifying a renewed focus on its core passion.

Design Philosophy and Identity

Marstrom Composite AB holds a formidable reputation in the sailing world, largely known as a world leader in the development and production of high-quality carbon fibre products. Their overarching design philosophy is deeply rooted in "Marine Passion and lightweight design," a principle that guides their work across all applications. They are celebrated for their expertise in lightweight composite constructions.

What truly sets Marstrom apart is their sophisticated construction techniques, particularly their pioneering work with autoclaved carbon fibre spars. This method allows for exceptional strength-to-weight ratios, crucial for high-performance sailing. The company operates as a contract manufacturer, boasting in-house design and stress calculation resources, enabling them to serve clients through the entire process from concept to completion. Marstrom Composite has also collaborated with renowned names and projects in the marine industry. Their long-standing design philosophy has fostered collaborations with entities like Dutch Xtender. They have also contributed to cutting-edge projects such as the V_REX, a visionary sailing vessel conceived by Peter Steinkogler, and have been instrumental in providing specialized components like the rig, bowsprit, lifting keel, and rudder for the high-performance Shogun 50.

Iconic Models and Legacy

While Marstrom Composite AB's legacy is often defined by its highly specialized components rather than entire production yachts, their impact on the marine industry, particularly in performance sailing, is undeniable. Their roots in the Tornado catamaran laid the foundation for their expertise in high-performance multihulls.

The company's most significant contributions lie in its production of advanced masts, booms, and other critical carbon fibre components that empower some of the fastest yachts on the water. Their spars have graced numerous high-profile vessels, including a 73-foot ULDB designed by Pelle Peterson. Marstrom's involvement extends to supplying integral parts for modern performance cruisers and racers, such as the Shogun 50, where they provided the rig, bowsprit, lifting keel, and rudder. They are also associated with the HH 88, described as a flagship model, indicating their ongoing commitment to top-tier yachting projects. Beyond new builds, Marstrom Composite actively supports the racing community, undertaking projects like rebuilding carbon fibre rudders and manufacturing new masts and booms for competitive teams like Pro4u. This extensive portfolio of components highlights their crucial, often behind-the-scenes, role in elevating the performance capabilities of a wide array of sailing yachts.

The Builder Today

Today, Marstrom Composite AB continues to operate from Västervik, Sweden, as a prominent subsidiary of the Scandinavian Astor Group AB. The company maintains its position as a leading contract manufacturer, leveraging its in-house design and stress calculation capabilities to deliver comprehensive solutions. Marstrom's current operations reflect a strategic expansion of its marine activities, catering to a sophisticated clientele that demands the highest standards in lightweight composite construction.

Their modern offerings appeal strongly to performance-oriented sailors, racing teams, and yacht designers who seek to push the boundaries of speed, efficiency, and durability through advanced materials and engineering. While specific details on a formal "owner community" are not explicitly stated, the nature of Marstrom's high-performance products and their involvement in competitive sailing implies a dedicated and discerning group of clients who value the unparalleled expertise and quality that Marstrom Composite AB brings to the world of yachting.
