Tykun H1 Hydrogen-Powered Dayboat Offers Fast Cruising and Full-Day Autonomy

Green screen: Introducing Tykun’s H1 hydrogen-powered, ready-to-build dayboat that, according to MED Group, offers fast cruising and full-day autonomy. MED Group, a leading builder of customizable aluminium performance chaseboats, has released more details of its hydrogen-powered Tykun H1. The H1 draws on the technical expertise of Tesya Group, which developed the hydrogen propulsion system for the America’s Cup chase boats. The company state the H1 will offer all-electric boating at speeds up to 35 knots and with a range up to 60 nautical miles thanks to a hydrogen-powered fuel cell. Fully engineered and ready to build, with a type-approved hydrogen system, a user-friendly system, and supported by NatPower H network.

After showcasing at the 2025 Monaco Yacht Show with the all-new, all-aluminium Tykun X customizable tender, MED Group has unveiled further details of its revolutionary new hydrogen-powered proposition.

Named the Tykun H1, the model has been fully engineered and is ready to build for customers who want to enjoy clean, green electric boating at speeds up to 35 knots, with extended range and built-in redundancy for flexibility.

The 12-metre H1 draws on the expertise of Tesya Group, which developed the hydrogen propulsion for the America’s Cup chase boats used during the 37th America’s Cup in Barcelona. The H1 also taps into the hydrogen infrastructure of NatPower H.

The MED Group team and designer Tommaso Spadolini have worked to integrate the hydrogen system into a 12-metre hull which draws on MED Group’s proven naval architecture and the customizable flexibility of aluminium.

The result is a boat that looks set to combine an advanced yet simplified propulsion system with functionality and seaworthiness, and the ability to accommodate high-spec dayboat and superyacht client requirements without compromise.

In essence, the Tykun H1 is an electric boat, with a battery bank powering electric motors. A fuel cell, powered by gaseous hydrogen, serves as a range extender by recharging the batteries and extending the vessel’s range to 60 nautical miles.

Crucially, the system also includes a regular shorepower connector for fast charging, meaning the H1 can be used as a high-performance electric tender even if there’s limited access to hydrogen.

Four concealed tanks hold around 32kg of hydrogen at a pressure of 350 bar. A simplified piping system delivers the hydrogen to the fuel cell which converts it into electricity with the only emission being pure water.

To ensure safety, the system uses equipment that has been Type Approved by leading classification societies.

The H1 is already garnering recognition, winning the Tenders/Water Toys category at the Monaco Yacht Show’s inaugural Blue Wake Awards in September 2025.

The Tykun H1 is fully engineered and the team state they are ready to begin construction with an estimated timeframe of 8 to 10 months for the build of the first prototype. Once series production begins, the delivery time for a new H1 vessel is estimated at between 6 and 8 months, with possible variations based on the level of customization required.
