Australian Waterbus Summit 2025 to be held on the NSW Central Coast

The Australian Waterbus Summit 2025, scheduled for mid-next year on the NSW Central Coast, aims to elevate public awareness of sustainable waterborne passenger transportation. It will serve as a platform for businesses, policymakers, and investors to explore emerging opportunities in this sector. A pivotal development in this field is the integration of electric hydrofoil technology into urban waterways, offering substantial advantages for both the public and passenger ferry operators.

7 key benefits of electric hydrofoil ferries

• Significant fuel cost reduction: Electric hydrofoil ferries can achieve up to an 80% decrease in energy consumption compared to traditional diesel-powered vessels.

• Zero carbon emissions: Operating on electric power, these ferries produce no direct carbon emissions, contributing to improved air quality and environmental sustainability.

• Quiet operation: The electric propulsion systems ensure near-silent journeys, enhancing passenger comfort and reducing noise pollution in urban areas.

• High speeds with minimal wake: Hydrofoil technology enables ferries to "fly" above the water surface, allowing higher speeds with minimal wake, thus preventing shoreline erosion and complying with no-wake zone regulations. 

• More frequent departures: The efficiency and speed of electric hydrofoil ferries facilitate more frequent departures, improving service availability for passengers.

• Lower maintenance requirements: With fewer moving parts and simplified systems, electric ferries require less maintenance, reducing operational downtime and costs.

• Flexible deployment: The adaptability of these vessels allows for versatile integration into various urban waterway networks, enhancing connectivity.

Broader impact

Adopting sustainable waterborne passenger transportation can alleviate road traffic congestion, encourage active transport modes like cycling and walking, and enhance urban connectivity. By leveraging existing waterways, cities can develop efficient and eco-friendly transit solutions that complement traditional land-based systems.

The Australian Waterbus Summit 2025 will play a crucial role in fostering dialogue and collaboration among stakeholders, paving the way for innovative transportation solutions that align with environmental and societal goals.

Why are hydrofoils are making a resurgence?

Hydrofoils, which have been around since the early 20th century, are experiencing a resurgence due to several technological, environmental, and economic factors.

Advancements in technology

• Lightweight materials: Modern hydrofoils benefit from advanced materials like carbon fiber and composite alloys, which are lighter, stronger, and more durable than the metals used in older designs.

• Improved hydrodynamics: Computational fluid dynamics (CFD) modelling and advances in automated control systems have optimised hydrofoil designs for greater stability, efficiency, and speed.

• Electric propulsion: Many new hydrofoils use electric motors, which are quieter and more efficient than traditional combustion engines. Electric systems also pair well with hydrofoils since reduced drag means lower energy requirements.

Growing demand for sustainable transport

• Energy efficiency: Hydrofoils reduce water resistance, enabling significant energy savings compared to traditional boats. This makes them attractive for eco-conscious transportation and recreational use.

• Reduced wake impact: Hydrofoils create minimal wake, which is better for fragile marine environments and shoreline erosion control.

• Reduced carbon footprint: Coastal cities and regions are looking for clean, efficient transport solutions to reduce congestion and carbon footprints. Hydrofoils, particularly in urban water transit systems, fit this need perfectly.

Popularity in recreational markets

• Water sports: Hydrofoil surfboards, kite-boards, and e-foils have surged in popularity, appealing to adrenaline-seekers and outdoor enthusiasts.

• Luxury yachts: Hydrofoil designs are increasingly integrated into high-end recreational watercraft, offering smoother rides and better fuel efficiency.

Support from public and private Investment

• Innovation: Startups and tech companies are investing heavily in hydrofoil technology, spurred by increased interest in sustainable marine transport. Governments are also providing funding for projects that promote clean energy and innovative transit solutions.

Challenges addressed

While hydrofoils still have operational limitations, modern systems are addressing historical challenges:

• Wave tolerance: Improved designs and active stabilisation allow hydrofoils to operate in rougher water conditions.

• Maneuverability: Innovations in foil configurations and control systems enhance steering and handling.

• Cost: Although still premium, economies of scale and material advances are making hydrofoil production more affordable.

In summary, hydrofoils are regaining popularity because modern technology has solved many of their historical limitations, while their efficiency and environmental benefits align perfectly with current global priorities.

Hyke Shuttle: Redefining urban waterway transport with all-electric innovation

The Hyke Shuttle is a 50-passenger, all-electric vessel developed in Norway, designed to enhance urban waterway transportation. While it may not achieve the high speeds and energy savings characteristic of hydrofoil ferries, the Hyke Shuttle offers unique versatility, making it an essential component of any city's passenger fleet.

5 key features of the Hyke Shuttle:

• Zero-emission operation: Equipped with an all-electric drivetrain, the Hyke Shuttle operates without emissions, contributing to cleaner urban environments.

• Energy efficiency: The vessel features a highly efficient hull and thermal system, with rooftop solar panels and automatic wireless charging at docks to optimise energy use.

• Passenger comfort: Designed with a spacious, air-conditioned interior, the shuttle provides a quiet and comfortable ride. Its barrier-free gangway ensures easy access for passengers with limited mobility, as well as those with bicycles or strollers.

• Smart technology integration: The Hyke Shuttle incorporates smart vessel control technology, including auto-docking features supported by sensor packs, enhancing operational efficiency and safety.

• Modular design: Its modular configuration allows for flexible deployment across various urban waterway networks, adapting to different passenger capacities and docking infrastructures.
