In this study, the relationship between service quality, customer satisfaction, and behavioural intention is investigated within a specialised nautical sports centre that offers kitesurfing in Portugal. Using a path analysis model, this study aims to evaluate the effect of the dimensions of service quality on satisfaction and behavioural intention, as well as the effect of satisfaction on the customer’s behavioural intention. According to the results, customer satisfaction is influenced directly by service quality dimensions such as responsiveness, assurance, empathy, and tangibility. This, in turn, positively impacts their behavioural intention to make future purchases. The responsiveness dimension directly affects behavioural intention, while empathy contributes to it indirectly through customer satisfaction. This study addresses a gap in current water sports research by examining the antecedents of customers’ behavioural intention, for the first time, to a nautical sports centre, deriving important managerial implications. Thus, to increase customer satisfaction and increase the likelihood of repeating their experience, it is advised that the sports centre implement clear work procedures, offer training to staff on responsiveness and empathy, and regularly gather feedback from customers to facilitate continuous improvement of their service design.
