SSY is based in Gävle, a city in the heart of the historic ‘iron kingdom’ dating back to the 6th century. Gävle is also a city with a proud tradition of shipbuilding. Along the Gävle River during the 1800s, there were a number of major shipyard companies that mass-produced merchant sailing ships. By the middle of the century, four of the six largest Swedish shipyards were in Gävle. This period was the peak of the city’s shipping industry, with five of the country’s largest shipping companies based in Gävle.
Briggen Gerda was built in Gävle in 1869. The ship was the last Swedish merchant sailing ship. A copy of Briggen Gerda was built in the early 1990s as a large social labor project.
SSY has revived boat building in Gävle and we hope to continue the city’s ship building tradition into the future. Our premises are located in the Gävle’s old shipyard area.
Håkan Rosén has always had a keen interest in the sea and boats. He started sailing at an early age and has owned a number of recreational boats later in life. He has been most passionate about wooden boats - although wood now has competition from Sandvik’s steel.
The family left hectic Stockholm in 2011 in favor of quality of life in Gävle. It was about then he heard about Sandvik’s new stainless steel, which is extremely resistant to corrosion.
“It should be possible to built boats from this material,” he reasoned. He first considered a sailing yacht in stainless steel, but realized it would be too heavy. He then began to consider how the Vikings managed to sail the seas in wooden longships over a thousand years ago.
These thoughts led to the idea of incorporating the Viking’s flexible hull construction in the structure of a steel boat. This began the development of the flexible longitudinal and now patented stringers, which together with Sandvik’s new steel, made it possible to build an extremely lightweight boat entirely from stainless steel.
The boat construction is tough and its lightweight ensures low fuel consumption. The new steel’s extremely smooth surface has also overcome a problem in the boat building industry. All metal under the waterline is mirror polished, which ensures that marine organisms that have attached to the hull are removed either with a low-pressure hose or at speeds as low as 5 kn. This therefore avoids the need for environmentally hazardous and expensive anti-fouling paints!
In January 2014, SSY moved into spacious premises in Gävle’s old shipyard area and began to build their first steel vessel. At the same time, a supplier was contracted to manufacture the interior modules for the prototype vessel.
Behind SSY is a group of specialists who have further developed Håkan
Rosén’s original concept. All have the vision to together develop an extremely environmentally friendly steel ships with superior characteristics compared with current plastic and aluminum ships.
SSY also has long-term plans to develop electric powertrains based on a micro hybrid turbine to avoid the need for diesel engines. This will be another significant step toward providing high-speed ships with even lower environmental impact than is currently possible with conventional diesel engines.
