A Firm Step Towards Sustainable Mobility

21 July 2025
Our innovative hybridization solution now enables the Catamarán Ciudad de San Sebastián to sail across La Concha Bay with zero emissions—marking a key milestone on the path towards sustainable maritime mobility. This strategic collaboration between Finanzauto and Catamarán Ciudad de San Sebastián not only transforms navigation in the bay, but also brings together two key players with a shared vision: driving the transition towards a cleaner, more efficient future.
As a symbol of this partnership, the vessel has been renamed Catamarán Finanzauto Ciudad de San Sebastián, reflecting a solid alliance that highlights technology, sustainability, and a joint commitment to the environment. Thanks to this transformation, the catamaran is set to consolidate its position as a benchmark for responsible and sustainable tourism in the region.

A Hybrid Solution Serving the Environment
The cornerstone of this advancement lies in the integration of a hybrid propulsion system, combining the traditional engine with a newly engineered electric unit, specifically designed to meet the operational requirements of this type of vessel. This achievement has been made possible through Finanzauto’s technical expertise and innovation capacity, delivering a tailor-made engineering solution adapted to the demanding conditions of the maritime environment.
Key benefits of this new system include:
- Zero-emission navigation within the bay, protecting the local ecosystem.
- Significant reduction of noise and vibration, enhancing onboard comfort for both passengers and crew.
