Candela Boats & Ferries C 8

THE BOAT

Lift off the water, and the noise disappears

Step aboard the Candela C-8 and it is the quiet that gets you first. No engine drone, no hull slapping at the chop, no wake unrolling behind. Push past sixteen knots and the boat lifts onto its foils and simply flies, silent and dead level, the far shore suddenly a short cruise away on a single charge. This is the calm of a sail with the range to actually go somewhere, the sort of thing owners tend to describe as closer to gliding than to driving a boat.

Candela Boats & Ferries C-8 — C8 SG-26
01SWEET SPOT

57 miles. 22 knots. Two and a half hours.

The Candela C-8 peaks its efficiency exactly where you want to cruise: at 22 knots, the foils are fully loaded, drag is cut up to 80 per cent, and the 69 kWh pack delivers 57 nm on a single charge. That is two and a half hours of silent, level flight, with genuine coastal range from a battery a third the size of what a planing electric boat needs to go half the distance. Speed and range, it turns out, pull in the same direction.

02OPEN WATER

Go fast where others must slow down

Most waterways post speed limits because fast boats leave a wake that erodes shorelines, rocks other vessels and generally makes a nuisance of itself. The Candela C-8 flies above all that: once on its foils, the hull is out of the water and the wake drops to under five centimetres, which on many restricted stretches means the speed limit simply does not apply to you. Quiet, clean, and leaving nothing behind, the C-8 goes further into places that have spent years trying to keep boats like this out.

03C-CONTROLLER

The computer that flies it for you

Push through sixteen knots and the Candela C-8's flight controller takes over the hard part: holding the hull steady, reading the foil's position one hundred times a second, and quietly capping the rate of turn before the foil can stall. What feels like instinct from the helm is actually aerospace-grade envelope protection running invisibly beneath you. The result is a boat that experienced mariners describe as intuitive from the first flight, and newcomers to boating tend to agree.

FAQ

Common C-8 questions, answered.

The Candela C-8 is an electric hydrofoil dayboat and premium leisure boat. It is designed for fast harbour and coastal use, but instead of planing on the hull it rises onto computer-controlled foils above the water.

The C-8 uses hydrofoils to lift the hull clear of the water at speed, reducing drag dramatically. That is what gives it unusually long range for an electric boat and a much quieter, smoother ride through chop.

It suits owners who want a premium dayboat with very low noise, low wake and electric operation for harbour, island-transfer and coastal day use.

It suits owners who want a premium dayboat with very low noise, low wake and electric operation, especially for harbour, island-transfer and coastal day use where comfort and efficiency matter more than carrying a large cabin interior.

The Candela C-8 delivers 57 nautical miles of range at a 22-knot cruise on its 69 kWh battery, up to three times the range of a comparable planing electric boat. Hydrofoiling cuts drag by up to 80 per cent, and without that physics breakthrough the numbers simply would not be possible.

Above 16 knots the Candela C-8 rises clear of the water in a matter of seconds, and what you notice first is not the speed but the silence: hull slap gone, spray gone, the boat hanging level and still above the chop. A flight-control computer trims the foils 100 times a second, so that calm holds even when the water underneath you is not.

The Candela C-8 is built to fly without specialist foiling knowledge, because the flight-control computer manages the foils automatically from the moment takeoff speed is reached. Everything from navigation to onboard systems runs through a single 15.4-inch touchscreen, and fly-by-wire steering means the boat responds like something from a different industry entirely.

The Candela C-8 charges from 10 to 80 per cent in around 35 minutes on a 135 kW DC fast charger, the same automotive-grade technology used by its Polestar-built battery pack. A standard 11 kW AC connection brings it to full in around 6.5 hours.

The Candela C-8 can run through one-metre seas with minimal pitching, because the flight controller reads wave height and direction continuously and adjusts foil angle to hold a level platform. If conditions push beyond the foiling envelope, the C-8 drops back to its hull and keeps moving.
