In the Amazon region, hydrological transportation has historically played a crucial role. However, passenger water transportation lacks economic models that assist in the design and implementation of strategies for its viability. In this study, a cost model for passenger water transportation was developed based on activity-based costing principles and linear programming. The aim was to optimize costs and maximize profits, considering demand and service level constraints in a water transportation company in the city of Belém, Brazil. The model was applied to three crossings that operate passenger, cargo, and vehicle trips between Belém and Ilha de Marajó. Various simulations were conducted to explore opportunities and conditions for reducing operational costs. The objective was to find the best cost-profit relationship, with the model parameters including variable costs, profits, and the maximum number of possible trips. Based on the results, alternative cost reduction strategies were established to achieve maximum profit and the highest number of trips. The model proved to be useful through the analysis of viable and effective cost reduction strategies
