Åsmund Lien on the Oselvar boat-building tradition of Os, Norway

Åsmund Lien is the manager of Norway’s Oselvarverkstaden, or the Oselvar workshop, where beautiful, hand-crafted Norwegian boats are built in a tradition that has endured for almost 2,000 years. The Oselvar workshop is located in the town of Os on the mouth of the Os River, for which the boat was named 250 years ago.

The significance of boat building in Os is not surprising—the town is situated on the western coast of Norway in Hordaland county, which is split from southwest to northeast by the long, deep Hardangerfjorden, one of Norway’s main fjords.

Åsmund has been the manager of the Oselvar workshop since it was established in 1997 with the aim of preserving the old artisan craft of boatbuilding that has been passed from generation to generation here since long before the Vikings. I, in turn, am delighted to pass on to you some of the Oselvar history that Åsmund shared with me when I visited the workshop last summer!

Meg: Can you describe a little bit about the historical significance of the Oselvar boat building tradition?


Åsmund: The Oselvar boat has a very long history. The boat’s current appearance has evolved from older types of boats, and it’s history goes back as far as there has been people living along the Norwegian coast. The clinker technique, a method of boat building where the edges of hull planks overlap, was introduced in Norway in the 3rd or 4th century AD—the Vikings used this same technique when crossing the oceans some hundred years later. Small boats from the Viking era are similar to the Oselvar boat in many ways, though you will find significant differences too. I believe that the Oselvar boat has been built using the same measurements for the last five or six hundred years.

The boat type got its name about 250 years ago, when two very skilled boat builders had their boat houses along the Os River. Oselvar means the boat built by Oselva. “Os” is an old Norwegian name meaning “river mouth.” Today Oselvarverkstaden is situated on the bank of Oselva, so the building of the Oselvar boats is located again at the origin of its name.

Meg: I know the device called a “Båtal” is essential to the boat’s construction—can you explain what the “Båtal” is?


Åsmund: All the measurements the boat builders need to build an Oselvar boat are marked with special symbols on this stick, which is called “båtal” – “boat ell.” {Ed. Note: an ell is an archaic measurement of length} This measurement stick is the complete plan for an Oselvar boat. I can give this stick to a boat builder and say: “Please, build this boat for me,” and he or she will be able to do that. I also need to know what type of usage is planned for each boat, in short, what characteristics I want for the boat.

Boat builders still use the “ell” as the main unit of measurement, but they use an “alen” dating back at least to early 1500. An ell in the boat builder’s vocabulary is 21 Norwegian inches, or 55 cm.

The Oselvar boat can be built in many different sizes, and there is one “båtal” to each size. The measurements on the stick are standard measurements. To “tailor-make” a boat, the boat builder needs to know if it will be used in the fjords or on open sea, if it is going to be sailed or rowed, whether any special fishing equipment will be used, and so on. Then the boat builder knows how much the measurements have to differ from the ones on the stick. If a fisherman for example is using a long line or net in deep water, he needs a boat that is wide and is able to lift a heavy weight. When you are using a long line and taking it up with many fish it is very heavy. When going up and down on the waves a wide built Oselvar will lift the long line and do the heavy work for the fisherman.

The boards in the boat are fastened together with rivets. Between the overlapping boards there is placed a cotton tread dipped in pine tar or oil, to make the boat tight. No glue is used in the boat.

The boat builders do everything from picking out the trees to make the boat ready to be launched. They go into the woods with their chain saw and tractor, they slice the timber logs into boards and planks, then build the boat, treat it with pine tar or oil before eventually putting it on sea–ready to be rowed or sailed. Constructing the Oselvar boat is to be done by hand and by eye. The throat of the boat, the bottom planks fore and aft, have a twisted shape and are cut with an axe. The boat builder starts with a plank of three inches and ends with a twisted board of about half an inch thickness. Each boat takes about 350 hours to make.

Meg: I had never heard of the concept of “Economuseum” before visiting the Oselvar boat shop. Can you explain that concept and the origins of the Oselvar work shop?


Åsmund: Oselvarverkstaden, (the Oselvar workshop), was founded in 1997 by Os Municipality, Hordaland County Council and Os Boat Builder Guild. The goal is to save the craft of building Oselvar boats and bring the skill to new generations of professional boat builders. The Oselvar boat is representative of the Norwegian clinker boat tradition, and of one that still is being built in the traditional way with the complete knowledge of building tradition alive.

When Oselvarverkstaden was established, the employees included two boat builders still earning a living from building Oselvar boats, together with two young, skilled wooden boat builders, who hadn’t built Oselvar boats before. The younger ones learned the Oselvar tradition by working together with the older ones. During the years since the work shop was founded, six apprentices have graduated, and three of them–two men and a woman–are now employed as skilled boat builders. One of these four original boat builders is still employed.


In 2008 Oselvarverkstaden joined the Economusee network. It is originally a Canadian network, based in Québec, and Oselvarverkstaden was the second company outside Canada to join the network. Now several enterprises in the North Atlantic area are members of the network. Economusees are handicraft enterprises producing traditional products of high quality with traditional tools and methods. The workshops have to be open for the public with an exhibition and access to see the artisans at work, and a shop where they can buy the products.

Meg: You were a co-founder of the Oselvar work shop—can you describe what motivated your involvement?


Åsmund: When Oselvarverkstaden was established I was in charge of the municipal office of cultural affairs. Os Municipality was one of the co-funders and was supposed to take care of the administration of the workshop, and thus I became the manager of the enterprise.

I have all my life been very interested in history in general and especially in local history, so I was glad to be given the opportunity to work on saving this very important craft, which is quite an important part of our national heritage.

Meg: Who are the clients of the Oselvar work shop and what do they typically plan to use the boats for?

Åsmund: A hundred years ago the Oselvar boat was the main fishing boat along the cost of Hordaland and western Norway, and it was used for all sorts of transport of people, goods and even domestic animals.

Until World War II, most families at the Norwegian coast were both fishermen and farmers. The wives ran the farm and the men fished. This way they always had a means to survive. During the 19th century the Oselvar became the main boat used by fishermen, who came from the islands at the coast of Hordaland to Os to have their boats built.

Historically the sea was the road and the boat was the vehicle. For hundreds and hundreds of years most all transportation of people and goods along the Norwegian coast and in the fjords was by boat on sea. In comparison the car’s history is not much more than one hundred years old.

Today the boat is used for leisure, rowing, sailing and fishing. Most of our clients are used to rowing or sailing this type of boat. If you love rowing you need to have a wooden boat. A plastic boat is built for an inboard or outboard motor, and a really bad fit for rowing.

The local market has always been most important for the Oselvar builders, i.e. the county of Hordaland and first and foremost the Hordaland coast. From about 1580, boat builders from Os and Tysnes delivered boats to Shetland, Orkney and Scotland. For the Os boat builders this was an important market for a period of 100 years or so, for the Tysnes boat builders close to 300 years. Today the same local market is the most important, but the workshop delivers boats to the rest of the country too, and also has clients in Denmark, Germany and the U.S.

The Oselvar boat has been famous for its characteristics as a good sail boat and a light row boat. Therefore the boat has been used for both sailing and rowing regattas. It is the oldest sail regatta class in Norway, and still there are arranged Norwegian championships in sailing Oselvar.

Meg: In researching the cultural traditions of Norway and Os in particular, I learned about rosemaling, a beautiful form of decorative painting on wood that uses stylized flower ornamentation and scrollwork. It was quite a serenipitous moment to see a boat embellished with rosemaling in the Oselvar work shop. Can you explain how that merging of these two traditions came about and whether or not the Oselvar boats are typically painted?


Åsmund: The rose painted boat in our reception area belongs to a musician called Orbo, who arranged a music festival last summer. When marketing the festival he wanted to combine the two strong and special craft traditions from this area, the Oselvar boat and the rose painting in the Os style. He bought this model of an Oselvar boat in scale 1:2, and asked one of the most prominent rose painters from Os to paint it. I have never seen a rose painted Oselvar boat before, but the painting itself is a very good representative for our rose painting tradition.

  1. Truly fascinating interview, Meg. I’ve long loved the water and boats, but this had so many interesting points about both making and using them. For example, the idea that the side-to-side undulation of a well-made boat can help the fisherman to sort of “pump” up a heavy net full of fish is brilliant.

    1. Thanks Jeff! It really is impressive how ancient man was so much more closely attuned to working with Mother Nature…vs against her, as so often seems the case these days. Norway is an incredibly pristine country and its citizens seem to really value her wisdom and bounty–both from a practical and recreational perspective.

  2. In 1732 Nicol Erasmuson of Pappa Little in the Shetland islands purchased a Yoal which is a Oselvar boat. These boats were made in Norway shipped in parts to the Shetlands and assembled by Norwegian boat builders. By 1732 the cod of the Shetlands had moved off shore so they had to rowed these boats more than 10 miles into the open ocean to catch fish. Nicol survived this dangerous fishing and as a result I’m living today. He was my many Great Grandfather.
