Abstract: Environmental protection and the rational use of energy also require a place in shipping. Battery technology has undergone incredible development in recent years. Thanks to the new types of batteries, electric-powered boats have become stronger and faster, while also protecting their environment. In the spring of 2018, the successor to the Calandra yacht came to the planning table and a new shipbuilding project called Calistra was launched. Calistra made its debut at the Budapest International Ship Exhibition in the spring of 2020. With its unique structural elements, it provides a high degree of variability in terms of dimensions, its sleek, modern design world simultaneously provides an aesthetic experience and a high degree of functionality. A ship with a modern appearance, which, despite its special shape, offers a huge interior space for any type of navigation, is ergonomically carefully designed, and its propulsion is not only strong, but also quiet, environmentally friendly. After the successful debut of the prototype, the elements of the ancient template are currently being manufactured, in parallel with which the components of the first ships will be made. The first ships are expected to be completed in early summer 2021. With its versatility, the resulting vessel is a multi-purpose, low-cost, and economically viable vessel that meets environmental standards and related societal expectations, and is part of sustainable development through its forward-looking, environmentally friendly operation. Calistra 700 EP New winds are blowing in the waters. But now they are not kneading sails. Is gasoline steam, horsepower rumbling, and roaring engine noise slowly became the past? We are not here yet, but environmental protection and the rational use of energy in shipping are also taking their place, and manufacturers are reacting quickly. Battery technology has undergone incredible advances in recent years, and small engines that used to move only fishing boats have become energy bombs flying serious boats. Thanks to the new type of batteries, electric boats have not only become strong and fast - feel free to believe your eyes in the video below, they really water ski with it - but they can stay out on the water for significantly more time thanks to the favorable consumption of the engines. So maybe we are slowly changing style and yet Lake Balaton will become a motorboat paradise? Calistra program, 2018-2020. After the highly successful Calandra yacht, it is time for us to meet the challenges of the age, but above all the needs of our customers. In the spring of 2018, the electric successor came to the design table, and our new shipbuilding project called Calistra was launched. After an army of variations that came to light at the idea exchange, the final version was completed. The debut of a ship in the spring of 2020 at the Budapest International Ship Exhibition, which with its unique structural elements provides a high degree of variability in terms of dimensions, its clean, modern design world simultaneously provides an aesthetic experience and a high degree of functionality. The end result has been a ship with a modern look that, despite its distinctive shape, provides a huge interior for any type of sailing, is ergonomically carefully designed, and is propelled not only strong but also quiet and environmentally friendly. After the successful debut of the prototype, the elements of the ancient template were manufactured, in parallel with which the components of the first ships were made. The first ships were completed in the spring of 2021. Compared to the prototype, the final ship received a higher level of equipment, rounded glossy plastic surfaces instead of aluminum edges, and an upper sun deck.
