Meet SARj and Andreas Cederqvist in discussions about environmentally smart solutions and good operating economics for ship propulsion. Environment and sustainability are in the spotlight. But what is actually the right choice in the commercial boating sector to achieve the greatest environmental benefit and at the same time maintain good profitability within the company. How will the ships of the future be equipped(?) electricity, hybrid, gas, or other biofuels? What driver systems and other technology solutions are available today and how can they create better profitability and control? This will be a journey in logical reasoning, insight into current suppliers' technology solutions and how SARj believes the marine sector will develop for small and medium-sized ships.
