Forget the highly-complicated chart plotters. All information & interaction is managed on a 12-inch multi-touch screen. The result is a fully integrated experience. We build our own PC Motherboards and write the code from inception. Height, roll and pitch are controlled by a specially in-house developed computer and software which constantly fine-tune the hydraulic controllers operating at an update frequency of 100 Hz. Take-off, cruising and landing are fully automated. The combination of all these innovations in a brand-new boat design allows us to optimize the benefits of each concept, something not attainable by just trying to modernize an existing hull. A carbon fiber hull, deck and structure reduce the total weight of the boat, including 230kg of batteries, to under 1300kg. Ultra-light shell materials are used to compensate for the weight of the battery and to further reduce the power requirements. The position of the actuators controlling the front and rear foils is updated at a frequency of 100 Hz (100 million operations per second), which allows very smooth and steady driving even in difficult wind and sea conditions. The boat is by nature inherently unstable in roll and height. “3圆" (position, speed and acceleration with respect to the position in x, y and x and rotationĪround the same axis) using advanced sensor fusion algorithms. Movements from 7 separate sensors: laser, inertial and gyroscopic determining the state matrix The performance and reliability of the flight is based on the control of the boat's The rear foil is retracted by a double rotational movement and protected by the bathing platform. The front foils are retracted vertically and protected by a step in the hull. Transporting on a trailer or especially for the storage in the garage of a large yacht respecting security and regulatory constraints A unique retraction mechanism solves problems encountered in shallow water or when A patented foil control system for height, roll and pitch, which is exceptionally reliable and Fully submerged foils also provide smooth cruising without wave slapping and with a minimum The reduction in energy consumption allows an electric propulsion with an excellent range. Hydrofoils reduce energy consumption by 50%. The concept is based on the following inventions and technologies: Several patent applications have been filed. It is the first electric pleasure boat in the world with electronically managed foils. Like a fighter plane: The the foils angle are adjusted 100 times per second. Manufacturer's remote intervention via a dedicated site monitored by PC orĦ. Very low maintenance costs thanks to a less complex electric power-train and the A per kilometer cost 95% lower than a comparable fuel-powered boat.ĥ. Virtually no wake protecting the coastlineĤ. Flying over the waves, avoiding the discomfort of slapping wavesģ. In addition to solving the range problem, the boat has the following features:ġ. A very lightweight design using carbon composites and construction techniques particular to An advanced control system which makes a naturally unstable boat incredibly stableģ. The Flying Boat concept which reduces friction by half compared to a conventional boat.Ģ. The reduction of energy consumption is achieved by adopting:ġ. The range achieved by Candela is ~4 times greater than that of the best electric boats currently on the market and is close or equal to that of combustion boats of the same size The challenge proved to be purely intellectual.īy the end of 2016, a full-scale prototype was launched and, following a few adjustments, the objective of surpassing 100 kilometers distance at a cruising speed of 45 km/h was achieved! This was the first time an electric pleasure boat managed to achieve such a feat. Today, we have, without doubt, the most advanced boat in the world. Therefore some of the world's brightest minds in their repected fields were brought together to develop state of the art: hydrofoil technology, carbon composites, transmission design, power electronics, dynamic modeling, self-learning, control theory and a lot of software development. However to meet the challenge - designing the world's first electric boat delivering speed and range - we had to think differently. The current market for electric boats is therefore small, estimated at less than 1%.īoat builders generally employ boat builders. IT IS INHERENTLY DIFFICULT TO DESIGN ELECTRIC BOATSĪ 7.5 m long pleasure boat consumes 12 to 18 times more fuel than a family car.Īt the same time, one kg of gasoline contains about 15 times more usable energy than one kg of the most compact batteries.įor this reason, electric boats are not considered a viable alternative to combustion-powered boats.Įxisting models obtain either speed or autonomy.
