Vies Braves (Sea Swimming Lanes) is a pioneer company in designing, promoting, and revitalizing open water and marine itineraries which are protected by buoys, and dedicated to health, leisure, educa- tional and environmental protection activities. The management team's strategic priority is the implementation of new Vies Braves in new coastal locations. In this paper, we propose a fuzzy decision-aiding ap- proach, using hesitant linguistic term sets to study the viability of new potential coastal locations. The proposed approach considers main eco- nomic, political, environmental and social criteria to nd similarities between each new alternative and existing ones.
