About Marex

Premium production

Norwegian family-boat builder founded in 1973 and now built in its own factory in Kaunas, Lithuania — seven cabin cruisers from the 9.5-metre 310 Sun Cruiser to the 13.7-metre 440 Scandinavia, with the Smart Canopy that closes the cockpit in under a minute.

Marex was founded in Norway in 1973 by Eyvin Aalrud, a former export manager for local boat builders, who started production at Rykene together with Joda. The first model, the 24 Sun Cab, was built in fibreglass on a Joda hull; the yard says 42 were sold at a single boat show and 432 in all between 1974 and 1987, and the 32 Friendship that followed became the largest Norwegian fibreglass boat of 1975. When the factory burned down in March 1979, production moved to Fjord's factory at Fevik in southern Norway, where the first Sun Cruiser 27 began a concept the yard has kept through more than five generations; the 77 Holiday of 1983 started the aft-cabin line. After the 1987 crash stopped sales in Scandinavia, the founder's sons Espen and Thomas built up dealers further south in Europe. Eyvin Aalrud died in 1998 and Espen took over, looking for manufacturing partners in Lithuania; the Scandinavia concept, with its wide glass sliding door and opening sunroof, arrived with the 330 Millenium in 2000, and production moved model by model to Kaunas, beginning with the 270 Estremo. From 2009 Espen Aalrud led development with Nikl Design, producing the 310 Sun Cruiser, 320 Aft Cabin Cruiser and 360 Cabriolet Cruiser, and in 2020 he began work with VOM Creation and the Alpha Group in Slovenia on the flagship Marex 440. Today the main facility in Kaunas has 28,000 m² of production area and, the yard says, 420 boatbuilders.
