The ﬁeld of ‘Craft Sciences’ refers to research conducted across and within diﬀerent craft subjects and academic contexts. This anthology aims to expose the breadth of topics, source material, methods, perspectives, and results that reside in this ﬁeld, and to explore what unites the research in such diverse contexts as, for example, the arts, conserva-tion, or vocational craft education. The common thread between each of the chapters in the present book is the augmented attention given to methods—the craft research methods—and to the relationship between the ﬁeld of inquiry and the ﬁeld of practice. A common feature is that practice plays an instrumental role in the research found within the chapters, and that the researchers in this publication are also practitioners. The aut-hors are researchers but they are also potters, waiters, carpenters, gardeners, textile artists, boat builders, smiths, building conservators, painting restorers, furniture designers, il-lustrators, and media designers. The researchers contribute from diﬀerent research ﬁelds, like craft education, meal sciences, and conservation crafts, and from particular craft subjects, like boat-building and weaving. The main contribution of this book is that it collects together a number of related case studies and presents a reﬂection on concepts, perspectives, and methods in the general ﬁelds of craft research from the point of view of craft practitioners. It adds to the existing academic discussion of crafts through its wider acknowledgement of craftsmanship and extends its borders and its discourse outside the arts and crafts context. This book provides a platform from which to develop context-appropriate research strategies and to associate with the Craft Sciences beyond the bor-ders of faculties and disciplines.
Dokumentation av båtar
(2019-05-23) Leijonhufvud, Fredrik; University of Gothenburg/Department of Conservation; Göteborgs universitet/Institutionen för kulturvård
The subject of this thesis is documentation of boats. Traditional boats and boat building skills are valuable assets of the cultural heritage and there is an urgent need of documentation and safeguarding. The aim of the study is to test and develop methods for the documentation of boats. The technology of digital Photogrammetry has evolved strongly in the field of heritage documentation and visualization, and in this study photogrammetry is evaluated as a method to record the complex shape of the boats hull. The possible advantages and disadvantages of photogrammetry as a tool for documentation are analyzed in comparison with traditional manual methods of recording a boats shape. The methods for digital documentation are refined trough the study and a work flow is created of how to record the boats shape in photogrammetry and export it to a CAD/boat design software. In the CAD/boat design software a conventional lines plan of the boat is produced. All documented boats in this study are built in the Nordic clinker boat tradition. In order to improve the methods of boat documentation on a general level a forensic perspective is used. The forensic perspective is a way to acquire as much information as possible from an object, using a palette of methods and perspectives. In this study the photogrammetry is one of these methods, mainly used to record the boats geometrical properties. In addition to the observed differences in technical properties and time/cost efficiency there is also an analysis of other impacts of each documentation method. The different methods impact on the interpretation and experience of the object is analyzed in the light of theory from the field of craft science. Tacit knowledge, tradition, intangible heritage and knowledge transfer are concepts often used in craft science, and in this study they are used to explain how objects can act as containers of knowledge and possibly even work as tradition bearers in a time-gap apprenticeship, learning craft skills from objects made by our ancestors. The important role of craftspersons in the interpretation of craft objects is stressed, especially in the interpretation of the objects craft properties and in documentation aiming for reconstruction of objects or craft processes. The study identifies a number of pros and cons of the digital photogrammetry and presents guidelines to improve a good practice of boat documentation. These guidelines can be helpful in documentation of other craft objects as well. A general conclusion is that photogrammetry can be a cost-effective and efficient method for the documentation of boats, but to reach a good practice of documentation it must be used with an awareness of its shortcomings and in combination with other methods of documentation.
I båtbyggarnas kölvatten: Tolkning och rekonstruktion av en hantverkstradition i Stockholms Skärgård
(Acta Universitatis Gothoburgensis, 2025-09-18) Fredrik, Leijonhufvud; Leijonhufvud, Fredrik
Through an analysis of old boats and craft reconstructions, this thesis explores historical boatbuilding traditions in the Stockholm archipelago and how craftsmanship skills were shaped and transmitted in the past. The thesis investigates how these and other craft traditions can be understood and reconstructed when no living tradition remains. The focus of the thesis is on the practical reconstruction process, where the interaction between boatbuilders, materials and functions in local waters is central, and on the historical context, where archival material provides insight into the lives of 19th-century boatbuilders. The öka boats in the Stockholm archipelago, a local variation of Nordic clinker boat traditions, were chosen as a case study. The öka boats are open, clinker-built vessels designed for both sailing and rowing, serving as versatile boats for fishing and transport from the outer skerries to sheltered waters. The thesis is based on diverse source material consisting of historical original boats and archival sources, which complement each other and are interpreted through reconstructions. These reconstructions contribute to an iterative reinterpretation that constantly develops understanding of the subject, in this case the boatbuilding tradition in the Stockholm archipelago. The theoretical framework is mainly hermeneutic, inspired by Hans-Georg Gadamer’s philosophy of interpretation and prejudice (1960). The affordance concept developed by James Gibson (1979) is used to analyse the relationship between the craftsman, materials, environment and tools. As a result of this research, the boatbuilding tradition is understood as a system of measurements and procedures but at the same time a system of flexibility – a set of rules of thumb rather than rigid standards. The variation in the shape and construction methods reflects both geographical differences within the archipelago and the practical conditions (affordances) that builders had access to. Certain misunderstandings about the construction of these boats are clarified; forgotten nomenclature is brought to life. This thesis shows that a particularly challenging area is reconstructing the abstract knowledge that the boatbuilder carries – the tacit knowledge of design and judgement that cannot easily be expressed in words or measurements. In summary, the thesis is an in-depth investigation of an older boatbuilding tradition of the Stockholm archipelago, where practical craft skills and historical research are combined to make visible and protect a multifaceted tradition. It highlights the complexity of cultural heritage, the need for new research methods and the importance of preserving non-living intangibles or traditions as part of a cultural heritage.
