History

edit

Marine Alutech was founded in 1991, although boats had already been manufactured under the Teijo shipyard since 1985. Niko Haro succeeded his father as managing director in 1998, and the company turned toward international markets. During its first 30 years (1991–2021), Marine Alutech delivered 522 boats. Its boats have been sold to several countries.[5]

In late 2025, Marine Alutech and the German company Schiffswerft Gebrüder Friedrich Kiel signed an agreement under which Marine Alutech’s boats would begin to be manufactured at the German shipyard in Kiel.[6]

Products

edit

Marine Alutech specializes in fast boats approximately 5–25 metres in length, with hulls made of aluminium and composites. Many of the boats use waterjet propulsion and reach top speeds of over 40 knots (~74 km/h), and even up to 50 knots (~93 km/h). The company’s customers are mainly military and government authorities, so the boats can be equipped with many types of systems and weapons, such as machine guns. The boats are outfitted, for example, for patrol, rescue, and combat use.[7][8]

Among Marine Alutech’s best-known products are the Watercat series boats, which include the Finnish Navy’s Jurmo-class (Watercat M12) and Jehu-class (Watercat M18) transport and landing craft.[7][8]
