Candela’s C-8 electric foiling boat has been named the European Powerboat of the Year 2023 at the European Powerboat Awards, also known as the ‘Oscars of the boat industry’.

The award presented at boot Düsseldorf last weekend recognises the C-8’s outstanding performance and innovation in the industry.

The Candela C-8 won the electric boat category thanks to its cutting-edge hydrofoil technology, which allows the boat to fly on water using only a fraction of the energy conventional boats need.

With a range of 50-plus nautical miles at 22 knots, the C-8 has two to three times the range of conventional electric boats and matches the performance of fossil fuel-powered speedboats.

Its active hydrofoil system ensures a smooth ride, while its onboard computer automatically adjusts for side winds and waves, providing a more comfortable boating experience.

The real game-changer lies in the C-8’s energy efficiency, according to its Stockholm-based manufacturer. With 80% lower energy consumption than conventional vessels and an almost non-existent wake, the C-8 causes minimal disturbance to marine life, Candela says.

In a recently announced partnership, Candela’s electric outboard engines will use batteries from electric premium car maker Polestar, which will allow the C-8 to achieve an even longer range, further pushing the boundaries of what is possible with electric boats.

“We’re committed to revolutionising the boating industry by creating electric boats that are not only more sustainable and environmentally friendly, but also outperform traditional fossil fuel-powered boats, thus accelerating the transition to sustainable boating,” says Mikael Mahlberg, Candela’s head of communications. “Winning the European Powerboat of the Year 2023 award is an important recognition for our work.”

The Candela C-8 is on display at boot Düsseldorf which closes today, Sunday 29 January. For more information visit candela.com.

After 16 months of intense development, the most ordered electric boat ever took off from the cold waters outside the Swedish tech company’s headquarters at Lidingö, Stockholm.

After reaching its designed take-off speed of 16 knots, the Candela C-8 prototype P-01 lifted off smoothly and flew noiselessly above the water at a cruise speed of 20 knots.

Smooth, and very, very silent, said Gustav Hasselskog, Candela’s CEO after piloting the C-8 on its maiden flight.

This first flight marks a huge moment not only for Candela, but also for the powerboat industry. The C-8 is not only designed to be the best electric boat, but it is also designed to be a far better experience than conventional powerboats. I hope we can drive the transition to emission-free boating at a very fast pace.

With Candela C-8, the Swedish tech company strives to disrupt waterborne transport by offering an electric boat that is better than ICE competitors, in all respects. 

The transition to zero-emission boats has been hampered by the inadequate performance of conventional electric boats. Propelling a planing, conventional speedboat through the water requires enormous amounts of energy, which drains even the biggest lithium-ion batteries after only 30-45 minutes of spirited driving.

Flying above the waves on computer-controlled hydrofoils – underwater wings – Candela’s craft use 80% less energy than conventional boats, which translates into far longer range and higher speeds on pure battery power.

What makes hydrofoils so effective is the dramatic reduction in drag. A typical planing hull has a 4-to-1 lift-to-drag ratio, while the Candela C-8 has a 20-to-1 lift advantage. Cruising at 20 knots, the C-8 can fly for 50 nautical miles on its 44 kWh battery – 2-3 times longer than conventional electric speedboats with 300% bigger batteries.

But the C-8 offers other and new benefits over any other boat.

Actively stabilized hydrofoils allow Candela electric boats to leave no trace; no pollution, no noise, no wake.

The C-8’s digital Flight control system automatically adjusts the foils to keep the boat level and steady, even in adverse weather conditions. The ride is silky smooth in choppy waves and side winds. The low energy usage directly translates into an almost non-existent wake. And the ride is silent, thanks to Candela's newly developed Candela C-POD direct-drive electric pod motor.

In an industry-first for leisure boats, the C-8 is equipped with fly-by-wire steering and has Autopilot features for more relaxed driving over long distances. When the driver lets go of the wheel, the boat will automatically steer the set compass course. More features will follow as the C-8 is upgradeable Over-The-Air.

The Swedish tech company has refined its hydrofoil technology and Flight control software since the open sportsboat Candela C-7 was introduced in 2019. With experience from the C-7, Candela’s 70+ engineers and technicians have designed the C-8 for rapid mass production, targeting a rate of 400 units per year in 2024.

As Afloat previously reported, Candela has received more than 100 orders since launching the C-8 concept last fall, which makes it the best-selling electric boat model in Europe, even outselling most other 28-foot ICE boats in the premium (€290 k) category.

This successful first flight brings us one step closer to serial production. We’ll now perform a rigorous flight test campaign to ensure reliability and maturity. We’re on track to deliver the first C-8 units this summer, says Gustav Hasselskog.

The Swedish tech company Candela has racked up more than 60 orders for its revolutionary, €290,000 electric boat, the Candela C-8. That makes the flying C-8 one of the fastest-selling 28-foot boats on the market.

The Candela C-8 is the next-generation electric boat from the Swedish tech firm Candela. Using a new version of the company’s patented hydrofoil system, C-8 flies above the waves with greater range than any other electric boat, powered by a new, silent pod thruster – the Candela C-POD.

Compared to the company’s first model, the smaller and hand-built C-7, the C-8 is made for rapid mass production which allows Candela to sell it for a price that is in line with conventional premium, fossil-fuel boats.

Five weeks after launching the C-8, Candela has more than 60 orders for it, which makes the novel electric powerboat one of the best-selling 28-foot premium boats in Europe.

According to the firm's data, the C-8 is the second or third fastest-selling powerboat in the 28-foot category in Scandinavia. Not just electric boats, but any type of power source. By year's end, we expect to have a real impact on combustion engine boat sales in this size category, says Mikael Mahlberg, Candela’s Communications Manager.

First long-range electric boat - intended for mass production

Candela’s first boat – the open Candela C-7 – was a sales success in its own right, but still a niche product. With 30 units delivered since production started in 2019, C-7 led premium electric boat sales in Europe on account of having longer range, higher cruise speed and smoother ride than other electric boats, thanks to the company’s hydrofoil tech that lifts the hull above the water friction and allows for long-range on battery power only.

Candela C-8 is a far bigger and more capable boat that will offer new features not found in other boats. Flying on computer-controlled hydrofoils that lift the hull above the waves and reduce energy consumption by 80% compared to traditional powerboats, the C-8 can cruise for more than 2,5 hours at 20 knots. The hydrofoils also reduce slamming by 90% compared to conventional hull boats.

  • The C-8 will not just have longer range than other electric boats, it will offer a better ride experience than any boat out there. In 3-4-foot chop, you’ll be able to drive at 30 knots without feeling the waves. It will be like a magic carpet ride, says Mikael Mahlberg.
  • The real game-changer is Candela’s new boat motor - the Candela C-POD. By putting the electric motors in a torpedo-shaped pod under the water, Candela gets rid of mechanical gears and the associated noise. Shifting to electric direct-drive also reduces the number of moving parts, making the Candela C-POD more efficient, and virtually maintenance-free. With 3 000 hours between overhauls, the Candela C-POD will last a human lifetime without maintenance.
  • The C-8 will be the first truly silent, fast motorboat. There’s no slamming, no noise from the transmission. You’ll be able to cruise along at 24 knots, with only the sounds of wind whistling past the windscreen, says Mikael Mahlberg.

First fully integrated boat

Candela’s 25-strong engineering team consists of experts in hydrodynamics, software, advanced computer simulations, mechatronics and electric propulsions systems, among other fields.

All software and most hardware – including the Candela C-POD motor and Flight controller that controls the foils in-flight - are designed in-house. Candela C-8 is a fully integrated boat, offering a seamless user experience. Gone are the myriads of physical buttons and knobs found in conventional boats. All features, from foil retraction to route planning, are managed by the 15,4-inch panoramic touch screen, which is running Candela’s intuitive User Interface. Boaters can also manage and monitor charging, route planning, heating etc from the Candela app. 

Foilborne without compromise

Thanks to the hydrofoils – two underwater wings – that lift the hull above the water friction, Candela C-8 can run for considerably longer distances than other electric, fast boats. At a cruise speed of 22 knots, the C-8 will cover more than 50 nautical miles (92 km) on one charge of its 45-kWh battery.

When foilborne, the C-8’s on-board computer, called the Flight Controller, adjusts and twists the hydrofoil about 100 times per second to maintain the best flight height and to counteract waves and side wind. This allows for an artificially stable ride, free from the slamming and pitching common in conventional motor boats.

In very rough seas that prevent hydrofoiling, the C-8 can also be driven as a conventional boat, albeit with reduced range. By pushing a button on the touch screen, the hydrofoils will retract into the hull. This feature is also useful when entering a shallow harbor, or when storing the boat on a trailer. When driving in Shallow Mode, the C-POD motor and C-Foil are retracted and fully protected from both fouling and hitting submerged objects.

Deliveries begin in 2022

The first Candela C-8 boat is being assembled in Candela’s Lidingö, Stockholm factory during December. First deliveries will start during spring 2022.

Ireland's Offshore Renewable Energy

Because of Ireland's location at the Atlantic edge of the EU, it has more offshore energy potential than most other countries in Europe. The conditions are suitable for the development of the full range of current offshore renewable energy technologies.

Offshore Renewable Energy FAQs

Offshore renewable energy draws on the natural energy provided by wind, wave and tide to convert it into electricity for industry and domestic consumption.

Offshore wind is the most advanced technology, using fixed wind turbines in coastal areas, while floating wind is a developing technology more suited to deeper water. In 2018, offshore wind provided a tiny fraction of global electricity supply, but it is set to expand strongly in the coming decades into a USD 1 trillion business, according to the International Energy Agency (IEA). It says that turbines are growing in size and in power capacity, which in turn is "delivering major performance and cost improvements for offshore wind farms".

The global offshore wind market grew nearly 30% per year between 2010 and 2018, according to the IEA, due to rapid technology improvements, It calculated that about 150 new offshore wind projects are in active development around the world. Europe in particular has fostered the technology's development, led by Britain, Germany and Denmark, but China added more capacity than any other country in 2018.

A report for the Irish Wind Energy Assocation (IWEA) by the Carbon Trust – a British government-backed limited company established to accelerate Britain's move to a low carbon economy - says there are currently 14 fixed-bottom wind energy projects, four floating wind projects and one project that has yet to choose a technology at some stage of development in Irish waters. Some of these projects are aiming to build before 2030 to contribute to the 5GW target set by the Irish government, and others are expected to build after 2030. These projects have to secure planning permission, obtain a grid connection and also be successful in a competitive auction in the Renewable Electricity Support Scheme (RESS).

The electricity generated by each turbine is collected by an offshore electricity substation located within the wind farm. Seabed cables connect the offshore substation to an onshore substation on the coast. These cables transport the electricity to land from where it will be used to power homes, farms and businesses around Ireland. The offshore developer works with EirGrid, which operates the national grid, to identify how best to do this and where exactly on the grid the project should connect.

The new Marine Planning and Development Management Bill will create a new streamlined system for planning permission for activity or infrastructure in Irish waters or on the seabed, including offshore wind farms. It is due to be published before the end of 2020 and enacted in 2021.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE.

There are a number of companies aiming to develop offshore wind energy off the Irish coast and some of the larger ones would be ESB, SSE Renewables, Energia, Statkraft and RWE. Is there scope for community involvement in offshore wind? The IWEA says that from the early stages of a project, the wind farm developer "should be engaging with the local community to inform them about the project, answer their questions and listen to their concerns". It says this provides the community with "the opportunity to work with the developer to help shape the final layout and design of the project". Listening to fishing industry concerns, and how fishermen may be affected by survey works, construction and eventual operation of a project is "of particular concern to developers", the IWEA says. It says there will also be a community benefit fund put in place for each project. It says the final details of this will be addressed in the design of the RESS (see below) for offshore wind but it has the potential to be "tens of millions of euro over the 15 years of the RESS contract". The Government is also considering the possibility that communities will be enabled to invest in offshore wind farms though there is "no clarity yet on how this would work", the IWEA says.

Based on current plans, it would amount to around 12 GW of offshore wind energy. However, the IWEA points out that is unlikely that all of the projects planned will be completed. The industry says there is even more significant potential for floating offshore wind off Ireland's west coast and the Programme for Government contains a commitment to develop a long-term plan for at least 30 GW of floating offshore wind in our deeper waters.

There are many different models of turbines. The larger a turbine, the more efficient it is in producing electricity at a good price. In choosing a turbine model the developer will be conscious of this ,but also has to be aware the impact of the turbine on the environment, marine life, biodiversity and visual impact. As a broad rule an offshore wind turbine will have a tip-height of between 165m and 215m tall. However, turbine technology is evolving at a rapid rate with larger more efficient turbines anticipated on the market in the coming years.

 

The Renewable Electricity Support Scheme is designed to support the development of renewable energy projects in Ireland. Under the scheme wind farms and solar farms compete against each other in an auction with the projects which offer power at the lowest price awarded contracts. These contracts provide them with a guaranteed price for their power for 15 years. If they obtain a better price for their electricity on the wholesale market they must return the difference to the consumer.

Yes. The first auction for offshore renewable energy projects is expected to take place in late 2021.

Cost is one difference, and technology is another. Floating wind farm technology is relatively new, but allows use of deeper water. Ireland's 50-metre contour line is the limit for traditional bottom-fixed wind farms, and it is also very close to population centres, which makes visibility of large turbines an issue - hence the attraction of floating structures Do offshore wind farms pose a navigational hazard to shipping? Inshore fishermen do have valid concerns. One of the first steps in identifying a site as a potential location for an offshore wind farm is to identify and assess the level of existing marine activity in the area and this particularly includes shipping. The National Marine Planning Framework aims to create, for the first time, a plan to balance the various kinds of offshore activity with the protection of the Irish marine environment. This is expected to be published before the end of 2020, and will set out clearly where is suitable for offshore renewable energy development and where it is not - due, for example, to shipping movements and safe navigation.

YEnvironmental organisations are concerned about the impact of turbines on bird populations, particularly migrating birds. A Danish scientific study published in 2019 found evidence that larger birds were tending to avoid turbine blades, but said it didn't have sufficient evidence for smaller birds – and cautioned that the cumulative effect of farms could still have an impact on bird movements. A full environmental impact assessment has to be carried out before a developer can apply for planning permission to develop an offshore wind farm. This would include desk-based studies as well as extensive surveys of the population and movements of birds and marine mammals, as well as fish and seabed habitats. If a potential environmental impact is identified the developer must, as part of the planning application, show how the project will be designed in such a way as to avoid the impact or to mitigate against it.

A typical 500 MW offshore wind farm would require an operations and maintenance base which would be on the nearby coast. Such a project would generally create between 80-100 fulltime jobs, according to the IWEA. There would also be a substantial increase to in-direct employment and associated socio-economic benefit to the surrounding area where the operation and maintenance hub is located.

The recent Carbon Trust report for the IWEA, entitled Harnessing our potential, identified significant skills shortages for offshore wind in Ireland across the areas of engineering financial services and logistics. The IWEA says that as Ireland is a relatively new entrant to the offshore wind market, there are "opportunities to develop and implement strategies to address the skills shortages for delivering offshore wind and for Ireland to be a net exporter of human capital and skills to the highly competitive global offshore wind supply chain". Offshore wind requires a diverse workforce with jobs in both transferable (for example from the oil and gas sector) and specialist disciplines across apprenticeships and higher education. IWEA have a training network called the Green Tech Skillnet that facilitates training and networking opportunities in the renewable energy sector.

It is expected that developing the 3.5 GW of offshore wind energy identified in the Government's Climate Action Plan would create around 2,500 jobs in construction and development and around 700 permanent operations and maintenance jobs. The Programme for Government published in 2020 has an enhanced target of 5 GW of offshore wind which would create even more employment. The industry says that in the initial stages, the development of offshore wind energy would create employment in conducting environmental surveys, community engagement and development applications for planning. As a site moves to construction, people with backgrounds in various types of engineering, marine construction and marine transport would be recruited. Once the site is up and running , a project requires a team of turbine technicians, engineers and administrators to ensure the wind farm is fully and properly maintained, as well as crew for the crew transfer vessels transporting workers from shore to the turbines.

The IEA says that today's offshore wind market "doesn't even come close to tapping the full potential – with high-quality resources available in most major markets". It estimates that offshore wind has the potential to generate more than 420 000 Terawatt hours per year (TWh/yr) worldwide – as in more than 18 times the current global electricity demand. One Terawatt is 114 megawatts, and to put it in context, Scotland it has a population a little over 5 million and requires 25 TWh/yr of electrical energy.

Not as advanced as wind, with anchoring a big challenge – given that the most effective wave energy has to be in the most energetic locations, such as the Irish west coast. Britain, Ireland and Portugal are regarded as most advanced in developing wave energy technology. The prize is significant, the industry says, as there are forecasts that varying between 4000TWh/yr to 29500TWh/yr. Europe consumes around 3000TWh/year.

The industry has two main umbrella organisations – the Irish Wind Energy Association, which represents both onshore and offshore wind, and the Marine Renewables Industry Association, which focuses on all types of renewable in the marine environment.
