For the time being, there is no way to operate a ship like Tambora without burning fossil fuels – by the ships’ main engine, to thrust the ship forward when there is not enough wind, and by its auxiliary engines to generate the electric power required to illuminate rooms and cabins, keep food fresh, prepare meals, fill dive tanks, and many others. While the usage of diesel cannot (yet) be avoided, we have gone to extreme length to keep it as low as possible. This means lower carbon emissions into the atmosphere. It also means no need for fuel surcharges.
Tambora’s propulsion system has been engineered for maximum fuel efficiency. At the heart is a new, genuine marine engine, which is significantly lower on fuel consumption. The five-blade propeller has been custom-designed and fabricated from a special, stiffer alloy, minimizing power losses due to both internal vibration and unnecessary slip. |
