Customized boat construction





The hybrid sail passage catamaran, “ECOSAIL”, built at the Dalmau Shipyards and inaugurated in Puerto de Barcelona in January 2019, it has been functioning in Barcelona since April 2019, with great success for his innovation at the sustainability and for the best panoramic views of the coast of Barcelona.

The propelling system has two electric motors and two diesel engines, that together with their sailing system, make this catamaran develop a silent navigation, comfortable and respectful with the environment.

Comfortable seats have been designed to be multi-purpose with the aim to adapt the boat every time, facilitating the development of events, tourist excursions, presentations of companies… and to have a sensation of walk with the private yacht.

The boat has been built to offer a quality experience, the maximum comfort of the passengers in order that have the sensation to sail alone boat, based on the innovation of the ecology and the conservation of the environment.
