The 3D model and documentary film detailing the building of the Bahari Yetu, Urithi Wetu ngalawa accompany an article on building a Ngalawa, a double outrigger logboat. The article documents master logboat-builder Alalae Mohamed’s construction of a ngalawa fishing vessel in Bagamoyo, Tanzania, in 2019. The ngalawa is an extended logboat with double outrigger and lateen sail: used by low-income, artisanal fishers. It is the most common marine vessel type of the East African coast. This article follows the construction process from Alalae’s selection and the felling of the tree(s) to the launching of the vessel. It outlines the tools and materials used, details the sequence he followed, and presents his choices and considerations made along the way. It is accompanied by a documentary film recording the construction process, a 3D digital model of the vessel and detailed construction drawings.
