Transmaçor was founded on 22 December 1987, from the merging of smaller operators that operated within the waters of the central group of Azorean islands. These included the Empresa das Lanchas do Pico, Lda., operator of the inter-island launches Espalamaca and Calheta; Empresa Açoriana de Transportes Marítimos, Lda, that operated the yacht Terra Alta; and Transcanal - Transportes Marítimos do Canal, Lda, owners of the traditional seagoing launches Picaroto and Manuel José. Transmaçor operated with 80% social equity in the operation, while the regional government held the remaining common shares. In 2011, the Regional Government of the obtained 88.37% of the common shares, with the remaining 11.63% stake taken by Empresa Açoriana de Transportes Marítimos, Lda. On 22 November 2012, the regional secretary for Tourism and Transport, Vítor Fraga, indicated the need to integrate and coordinate inter-island travel between land, air and maritime traffc, resulting in an Integrated Plan for Transport. Fraga indicated that it was necessary to "rationalize the system, evolving into an integrated management of Atlânticoline and Transmaçor, by fusion, that permitted the desired economies of scale and a better optimization of operational results", noting that "on concluding, the construction of two new mixed-transport vessels for passengers and vehicles" was necessary. By the beginning of 2014, the proposed merger of the inter-island operators had not occurred. While maintaining the brand Atlanticoline, the Government of the Azores would reform the new entity at the end of the mandate of the old Atlanticoline administrative council on 31 December 2013, but maintain the daily operation independent. The arrival of the two new RORO-enabled mixed-use vesselsGilberto Mariano and Mestre Simão at the end of the summer, in the colours of Atlanticoline did not indicate a separate-but-equal operation of the new operator.
