Candela C-POD

A new frontier
The Candela C-POD is the most efficient and long-lasting boat motor ever made. Two ultra-compact yet strong permanent magnet motors under the water provide unrivaled range and efficiency. Enough thrust to make our boats fly at a speed of 30 knots, in absolute silence.
Electric direct-drive means no noise from gears, no oil changes and no maintenance. The patent-pending Candela C-POD will last a lifetime, without needing service.

Candela C-POD –
The ultimate boat motor

  • Efficiency
  • Built to last
  • Whisper quiet
Candela C-POD is the first electric pod motor designed for high-speed boats. The direct, all-electric drive reduces friction to a minimum and provides 23% more range than the best electric outboards. Custom-designed electric motors enables a power density that is 4 times better than competitors.
Candela C-POD requires no maintenance and will last 3000 hours without service. No need to change oil or cooling fluid, as the sealed electric motors are cooled by the flow of seawater.

Combined with the low running costs of Candela’s hydrofoil craft, Candela C-POD makes for truly trouble-free boating.
By placing the motors under the water, we get rid of typical squeaking and whirring sounds from gearboxes and mechanical transmissions. Thanks to the Candela C-POD, Candela’s hydrofoil crafts are the most silent electric boats on the market. At any speed.


Established Truths
In 2014, a task group was assembled containing some of the leading experts within structural composite engineering, fighter jet flight control electronics, America’s Cup hydrodynamics, dynamic modeling and drone control systems. The venture was to find ways to make electric boats that would offer the elusive combination of both range and speed. Solving this crux would radically change the boundaries of electric boats.
After 10,000+ hours of simulations, design iterations and sea trials, a solution was found which is robust, fast and extremely efficient.

At the end of 2016, a full-scale prototype was launched, fulfilling the target of more than 50 nautical miles per charge at a speed of 22 knots.

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

The innovation formula
behind the success

  • C-FOIL system
  • Ultra-light build
  • Avionics
Hydrofoils remove 50% of the drag compared to a planing boat. This is the most important principle in our design. Hydrofoils can be designed in different ways with varying efficiencies and behavior. We opted for the most efficient and precise solution possible, which is fully submerged foils. Other types of foiling systems are less efficient and are therefore not suitable for electrification.

Similar to a traffic airplane: Candela’s craft use a large, straight main foil close to center of gravity and a smaller T-foil in the aft. The foils are retractable for trailing, storage and shallow water operation.
Batteries are heavy. In order to make up for this, we needed to make the hull extremely light, while still rigid and strong. The solution was making it with 100% carbon fiber, which allows the Candela hydrofoils to weigh significantly less than a similar boat of the same size.
A flying boat with submerged foils needs active stabilization. That’s why we at Candela are industry-leading in combining electric propulsion with hydrofoiling.

The software and electronics are engineered to allow us to design a precise and performance-driven experience in rough sea and sharp turns. The flight control system uses a variety of sensors to estimate the position, velocity, and acceleration of the boat on all axis. Further, it combines measurement from more than 10 sensors, to estimate the true state of the system at all times.

Here’s the top five.

What is the range at high speed?

Real-world and validated range is 50 nautical miles at 22 knots. This means you can cruise for more than two hours without noise, emissions, or wake.

What motor and battery do you use?

Candela C-7:

Battery: 40 kWh lithium ion NMC battery pack (from BMWi3).
Motor: 70 kW for take off, 16 kW in 23 knots, 37 kW full speed.

What is the cost of driving a Candela Seven?

The C-7 is 95 percent cheaper to drive than a gas-powered boat! A full charge costs 5-7 €. A comparable fossil fuel bowrider would use fuel for 200 €.
