Monohull masts... We have produced many hundreds of spars since the end of the 80´s. Marstrom was one of the first builders in the world able to produce high performance masts by using pre-preg and autoclave technology. We have a serie of moulds which will meet your demands, from 30 to 100 foot yachts. We also have an inhouse mould production that can meet any demands on the market.

In the course of the years; we have developed, designed, manufactured and delivered over 5,000 carbon fibre masts of different configurations and sizes; from 5,5m E-Dinghy masts to specially developed masts for America's Cup boats. Spars up to 35 m can be cured in our longest autoclave.
