SeaBubbles: flying boats for green, silent mobility on urban waterways

© SeaBubbles

Is the market for flying boats finally coming to fruition? Since its creation, SeaBubbles has dreamed of reinventing urban mobility on water. With its electric hydrofoil boats, the Lyon-based start-up aims to transform waterways and waterways into a sustainable, environmentally-friendly and noise-free transportation network.

In 2016, visionary Alain Thébault, alongside windsurfing champion Anders Bringdal, laid the foundations for a project: SeaBubbles . Inspired by his previous sailboat, "L'Hydroptère," a trimaran that flew above the water thanks to its foils, Thébault is transposing this technology, hoping to breathe new life into the waterways of major cities, while respecting the ecosystems crossed.

Designed to sail above the surface thanks to its hybrid hydrogen-electric propulsion and automated foils, SeaBubbles offers a zero-emission, noise-free transport solution perfectly suited to urban waterways and waterways. From the outset, the company succeeded in attracting investors and raising funds to build a fleet and develop charging stations in Europe. Alas, the business reality was different...

Taken over in 2020 by Meddiapps Innovation, SeaBubbles today embodies a model initiative for green mobility, seeking to transform city waterways into sustainable, environmentally-friendly transportation networks. Find out more about this ambitious project and the boat models currently available for pre-order from SeaBubbles.

Metropolises connected by waterways

SeaBubbles imagines a future in which waterways are at the heart of urban mobility, transforming rivers and waterways into real transportation routes to relieve congestion in major metropolises.

By integrating SeaBubbles into urban mobility applications such as Uber, the aim is to enable users to easily book a boat trip as they would a car journey. These zero-emission boats are perfectly suited to the needs of modern cities, offering a clean, efficient transport solution for cities that are both more breathable and connected by their rivers.

Versatile, SeaBubbles can be used for a wide range of purposes, from passenger transport and tourism to bay and lake shuttles. Their ability to navigate in both fresh and salt water, and their sturdiness at sea up to force 5, make them an ideal option for communities keen to reduce their ecological footprint.

Currently being tested and demonstrated on sites such as Lake Geneva, San Francisco Bay and London's River Thames, these boats are not yet available to the public for regular trips. However, a full-scale test was carried out on Lake Annecy during the summer of 2024, using an electric propulsion solution (no hydrogen pilots). Thanks to their innovative technology and commitment to reducing noise and pollution, SeaBubbles could provide an effective response to today's sustainable mobility challenges.

Reducing ecological impact with hydrofoil technology

SeaBubbles incorporate a hydrofoil system as the backbone of their clean sailing technology. Equipped with inverted T-shaped foils inspired by aeronautics, these boats, governed by an internal intelligence, rise above the water as soon as they reach 10 knots (18 km/h), limiting friction and optimizing energy use.

By flying above the water, SeaBubbles reduce their energy consumption by 35%, while maximizing their autonomy. This concept, which favors gentle, environmentally-friendly navigation, avoids wakes and protects ecosystems. SeaBubbles are therefore particularly well suited to ecologically sensitive areas such as rivers and lagoons, where stability and reduced CO2 emissions and noise pollution are paramount.

Except that the city of Paris has refused to accept these machines, which move too fast. The speed limit on the Seine is 18 km/h. No derogation has been granted to SeaBubble to practice transportation in this city...

A unique navigation experience

For those who have tested it, boarding the SeaBubble means embarking in a silent, comfortable capsule resembling a bubble gliding over the water. Equipped with gullwing doors, it offers easy access for passengers, who benefit from a space optimized for comfort and stability.

When cruising, the SeaBubble flies over the water at an altitude of 60 cm, eliminating the seasickness often associated with traditional sailing. The cockpit, designed to withstand the stresses of navigation, guarantees safety and an enhanced sensory experience, between buoyancy and lightness.

The different SeaBubbles models and their technical specifications

SeaBubbles are sophisticated systems with an internal intelligence that automatically manages flight and energy regulation on board. SeaBubbles engineers implement protocols to secure the experience, optimize energy and meet flight requirements, ensuring a safe and fascinating ride for passengers. SeaBubbles can reach a maximum speed of 18 knots (33 km/h). Here are the main models available for pre-order:

1 - The Bubble

The Bubble is SeaBubbles' entry-level model, designed for short trips, sightseeing and pleasure boating. Priced at around 250,000 euros, this compact boat combines cutting-edge technology with an elegant, minimalist design. Carrying up to 5 passengers, The Bubble offers silent, vibration-free cruising, for total immersion in the natural environment.

  • Speed and automated flight: Sailing at 12 knots, The Bubble literally takes off from the water at 6 knots thanks to its automated foils. In just 3 seconds, the hull is in the air, ensuring a smooth, jolt-free crossing with no wake. A regular boating license is all you need to pilot it.

2 - Smart Bubble

The larger, more powerful Smart Bubble is ideal for city transport services, business travel or group tourism. With a capacity of 6 to 12 passengers, prices for this model start at 650,000 euros. It is ideal for fast travel in congested urban areas such as ports, lakes or canals.

  • Speed and stability features: Equipped with a hybrid motor (electric battery and hydrogen fuel cell), the Smart Bubble reaches a speed of 16 knots (29 km/h). This model is also equipped with an advanced stabilization system for smooth, roll-free sailing.

  • Versatility and energy savings: By opting for a hybrid system, SeaBubbles offers greater flexibility for longer non-stop journeys and reduced recharging times.

On October 14, 2024, SeaBubbles reached a new milestone by obtaining approval for its second flying boat model, designed to appeal to private customers, including hoteliers and transport operators. Following trials on the Seine, SeaBubbles has extended its tests to Lake Annecy, where its flying boats are now available for hire for cruises or seminars. At a time when the market for innovative river transport is still maturing, SeaBubbles is pursuing its development in anticipation of the regulations that should stimulate this sector in the years to come.
