Marstrom shipyard, founded in 1984, is known for producing high-quality carbon masts. Although it is little known, it is highly regarded at Olympic level. Marstrom won a bronze medal at the 1984 Olympics, thus obtaining a monopoly on the Olympic Tornado and most of the equipment in the Europa class, with over 4000 masts produced. These masts are known for their exceptional durability, maintaining the same dynamic bending values even after many years. Initially, the production of carbon masts was limited and mainly intended for the Olympic sector. However, with the move to the new premises in Vastervik, the company expanded its production, making carbon masts its core business and targeting new markets.
The shipyard has a marina with a capacity of over 100,000 m², capable of accommodating more than 200 prestigious boats; It also stands out for its in-house engineering studio, which uses finite element analysis (FEM) to design and develop structures. Marstrom collaborates with companies such as Dehler, Sweden Yacht, Baltic and Swan, and has attracted investment from Saab Aeronautics for innovative projects, such as the supply of masts for the Baltic 68’ Café Racer.
A unique feature of Marstrom is the use of female molds and autoclaves in the production of masts and hulls for multihulls. This technique eliminates aerodynamic interference and ensures the linearity of the external layers of the laminate, which respond to tensile and compressive stresses. The molds, made of the same material as the laminate, prevent slippage and intralaminar detachment, maintaining the stability of the stresses. After internal reinforcement, the molds are closed and fired in an autoclave at 6.5 atmospheres and 125 degrees, creating a monolithic product without the use of glues or fillers. Marstrom can produce one-piece masts up to 35 metres and will be the first company to use this technology for an America’s Cup mast. The steel fittings are produced by a specialist company in the group, allowing for customised solutions. Marstrom works with leading rigging companies, such as Nitronic and the increasingly popular “carbon rigging”, which allows for customisation for extreme cruising and racing. The mast supply includes a custom mast jack and accessories such as instrument holders and carbon steering wheels, combining lightness with advanced technology.
