In the Roman world, those who ran was considered a loser, someone to be pitied, if not really despised. It seems that the wisdom of our ancestors can be useful to us, in all fields of our life, even in the nautical one. During a live Instagram of Fluid / us with Riccardo Sassoli, a nautical expert, clear directions emerged for the sustainable development of the sector. Analyzing how boating can embrace the need for sustainable development, it became clear that the real problem lies in the immeasurable consumption of diesel that today's boats produce, compared to this, the fact that most of it is made of fiberglass, a non-material material. easily disposed of, it becomes a false problem. When an average boat of 20/30 meters consumes something like 700/800 liters of diesel per hour, it becomes clear how the improvement can lie primarily in the search for other ways of propulsion. Of course, you can calm down and wait for some willing legislator to propose a speed limit, but you risk making the horse die as the grass grows. The alternation exists and the automotive world has already married it, the electric motor is a reality, it is not yet powerful enough to meet the needs of much heavier vehicles such as boats, but given the great progress made in the last few years. years, it is to be expected that soon a solution will arrive from that sector that can be translated into the nautical world. In the meantime, one looks with amazement and growing interest at the unexpected fact that, thanks to new technologies, good, dear, old sailing boats have now become faster than motor boats. Could the solution be hybrid? Combined wind and electricity? Will an electric wind propel the boats of the future?
