Why put an electric boat on foils?
The hard part of an electric boat has never been the motor. It is the water. Anything moving through it has to shove it aside and drag a wave system along, and the energy that goes into building those waves is gone for good. A displacement hull runs into a wall as it approaches hull speed, the point where its own wave swallows extra power without giving back much speed. A planing hull climbs over that wall, then pays a permanent tax in drag to stay on top of the surface. Gasoline and diesel boats hide the bill behind fuel that is cheap and energy-dense. An electric boat cannot: every kilowatt-hour lost to drag comes straight out of your range, and the battery that would compensate is heavy, expensive and finite.
A hydrofoil attacks the problem where it starts. Past a takeoff speed the wings under the hull make enough lift to carry the whole boat, the hull rises clear, and the wetted area shrinks to the slim struts and the foils themselves. Drag collapses, and the wave behind the boat goes with it. Candela puts the saving at roughly 80% against a planing boat of the same size, and that number survives contact with the real world: measured data from scheduled commuter service in Stockholm has the P-12 ferry using 84% less energy per passenger-kilometer than the diesel vessels on the same route, with 95% less CO2. Navier, in California, reports 90% less drag and running costs that drop from $4 to 38 cents per nautical mile on its own boat.
Numbers like that change what an electric boat can be. Instead of a short hop with one eye on the state of charge, the same pack covers several times the distance at a real cruising speed. On inland lakes that restrict or ban combustion engines, electric propulsion is the entry ticket anyway; the foil is what decides whether that ticket feels like a compromise or an upgrade. Quiet, vibration-free flight is also the experience premium buyers are paying for. If you want the physics in more detail, our page on hydrofoil boats takes it apart, and the wider category is covered under electric boats.
What changes once the hull leaves the water
Efficiency is the headline, but it is not what passengers notice first. Wave motion weakens quickly with depth, so wings running a meter or so under the surface pass through water that is far calmer than the chop above them. A foiling boat flies over short waves instead of slamming into them. No pounding, no sheets of spray, no engine noise, and conversation at cruising speed stays possible. If you get seasick on a hard-riding planing boat, that difference on its own can sell the whole concept.
The second change is the wake. With almost no hull in the water there is almost no wave to leave behind, which matters more than it sounds: wake is what unsettles swimmers, rocks moored boats and chews at shorelines, and it is the reason so many harbors, canals and lake shores impose speed limits. A flying hull is inherently well behaved there. It still has to obey the same limits as everything else, but it is the rare powerboat that is not the problem those limits were written for.
There are trade-offs, and they are worth knowing before you fall in love with the idea. Below takeoff speed the boat is an ordinary hull: it maneuvers, docks and behaves like one, so harbor handling is familiar rather than magical. The wings hang below the hull, which makes shallow water, sandbars, weed, floating debris and standard launch ramps things you have to plan around. ENVGO answers that with foils that retract. And the foils do not balance themselves: sensors and a flight computer trim them constantly, fifty times a second on the Navier N30. Hydrofoils themselves are an old idea. What arrived recently is cheap sensing, fast actuators and control software good enough to make flight boring, which is exactly what you want from it.
What foiling does not buy you is a legal shortcut. To the authorities a boat like the Candela C-8 is a powerboat with the length, power and passenger count it has, and the licensing, registration and right-of-way rules attached to those numbers apply unchanged. The specifics differ enormously: rules vary by country and often by individual lake or stretch of coast, the thresholds that trigger a license are set nationally in some places and state by state in others, and individual inland waters add their own emissions or access conditions on top. Check what applies at the water you intend to keep the boat on before you sign anything, not after.

The 2026 field: who builds flying electric boats?
2026 is the year the category stopped being a prototype story. Boats from two builders carry paying passengers on published timetables, and the largest order for electric ferries yet signed is on the books. Here are the names that matter, in order.
Candela (Sweden): the benchmark
Stockholm-based Candela sets the standard everyone else is measured against. It builds the C-8 daycruiser (8.5 m, a 69 kWh Polestar battery, 57 nautical miles or about 105 km at cruising speed) and the P-12 electric foiling ferry. 2026 brought real momentum: in April the Norwegian transport operator Boreal ordered 20 P-12s, the biggest electric ferry fleet order ever placed, and the range grew with the P-12 Business for 20 guests and, in June, the P-12 Voyager, a luxury 12-passenger variant. The P-12 Nova has been running a daily timetable in Stockholm since May 2025, and in February a P-12 set the record for the longest electric sea voyage at 160 nautical miles. The map is filling in just as quickly: eleven P-12s are entering service in Mumbai, among them an airport route that turns a two-hour drive into 35 minutes, and deliveries have started to the Maldives, Thailand and Germany.
Vessev VS-9 (New Zealand): the other one carrying passengers
The VS-9, from Auckland builder Vessev, is 8.95 m long, carries 10 guests on 105 kWh and cruises at 25 knots. It has been carrying paying passengers in the Fullers360 fleet since January 2025, making it the second certified electric foiling passenger vessel in commercial service alongside Candela. Fully loaded, the battery is good for about 40 nautical miles (74 km). A leisure version called the VS-9 Skye appeared at the end of 2025, and the first European boat goes to a resort in Northern Ireland in 2026.
Navier N30 (USA): the Silicon Valley boat
California-based Navier builds the N30 at 9 meters, with room for 9 people and a choice of an 86 or 114 kWh battery. At 20 knots it covers 70 nautical miles (around 130 km) on a charge, one of the best figures in the class. Its canard foils sit forward and are trimmed by the onboard computer fifty times a second. The first boat was handed over in October 2024, sales currently run by invitation, and from 2026 a hundred N30-based water taxis go into service in the Maldives.
Artemis Technologies EF-24 (UK): the heavyweight
Belfast-based Artemis Technologies works at the industrial end of the scale. The EF-24 Passenger is a 150-seat electric foiling ferry with a 34-knot cruising speed, 70 nautical miles of flying range and a full charge in under an hour. The first three vessels were finished in January 2026 and enter service around Belfast, the Orkney Islands and Southampton. Artemis is also building the world’s first electric foiling pilot boat, the EF-12 Pilot, which starts sea trials in the summer of 2026.
Tyde x BMW (Germany): the luxury experiment
Tyde, based on Lake Starnberg in southern Germany, builds The Open together with BMW: a 14.7-meter open foiler with around 400 kWh of BMW i3 battery modules, two 100 kW Torqeedo drives, a 25-knot cruise, 50 nautical miles of range and a solar roof. Tyde quotes the same 80% energy saving. The company is active and runs a configurator, but we found no public confirmation of customer handovers, so treat this one with some caution for now.
ENVGO NV1 (Canada): the newcomer
The NV1, built in Canada by ENVGO, is the sportiest boat in the group: 8.3 meters, 6 people, 80 kWh, a 245 kW peak and a top speed of 43 knots (about 80 km/h, roughly 50 mph), with retractable foils and DC fast charging. The company closed a US$2 million seed round in June 2025 (reported by BetaKit) and the boat flies at demonstrations, but there is still no word of series deliveries to customers.
Out, pivoted, or never electric
Not every promising name is still in the race. The Dutch company Edorado has effectively shelved its 8S and now concentrates on supplying foil systems and on defense projects. France’s SEAir develops foil technology, but its own product line runs on gasoline and diesel. The Enata Foiler has moved to pure diesel power, so it flies, just not electrically. And Sweden’s Mantaray shows an interesting alternative with mechanically self-regulating foils, though the official model range comes with gasoline engines; it has only flown electrically at press demonstrations.

Buying one: availability, charging and what comes next
Availability is better than most people assume and still nothing like walking into a dealership. The first boats are out there: Candela has customer deliveries running on several continents, Vessev put a leisure version of the VS-9 on the market at the end of 2025, and Navier sells by invitation. Nearly all of it happens through individual quotes rather than published price lists, which makes budgeting a conversation rather than a spec sheet. Raise service and spares early in that conversation, because a flight control system is not something every boatyard has worked on.
The practical question is charging. Shore power is the norm at marinas, usually a 16 or 32 amp connection, and that is comfortable for an overnight charge on packs of this size. DC fast charging for boats is a different story: outside a handful of commercial berths built for scheduled services, it barely exists, so the half-hour top-up a C-8 is capable of stays theoretical in most places. If you plan long days on the water, sort out what your home berth can actually deliver before you buy the boat, not after the first flat battery.
The bigger story is public transport. Norway has ordered twenty flying ferries, the P-12 runs a daily timetable in Stockholm, and the measured data says it is both faster and cheaper to run than the diesel boat it replaced. Artemis puts 150-seat foiling ferries on routes around Belfast, the Orkney Islands and Southampton, and Auckland has been carrying passengers on a Vessev since early 2025. Every one of those is a short crossing, exactly the distance these boats are built for, and short crossings like them are still run on diesel almost everywhere else.
For private owners the timeline depends less on the boats than on the dock. Sheltered inland lakes and calm coastal bays are close to ideal terrain for this technology: distances are short, the water is flat, and wake matters to everyone else out on it. Many of those waters already restrict combustion engines, so the boats running on them are electric anyway. They just do not fly yet.
