“Kayak House” manufactures and sells catamarans, motorboats and kayaks. Their solution envisages the construction of a solar catamaran for navigation on Serbian rivers and lakes, especially in areas where boats with internal combustion engines are prohibited, which will contribute to the development of ecotourism. Promotional tours and workshops will be organised for children with disabilities and children without parental care, enabling them to learn about the production of catamarans, renewable energy sources and environmental protection.
