Marstrom Mulltihull spars, all sizes, racing or cruising doesn’t matter, we produce it all! We have a range of tools from A-Cats, (9,3m) up to - 90 footer (40m) for the moment; there is no limit in size. All masts are produced with the same female tooling and "one shot process", no joints and all reinforcements on the inside of the tube. Rotating masts were the first type of masts we produced back in the 80's. Almost all types of configurations have been tested during the years and we are willing to share the experience with you.
