E-Hybrid-36

HAARLEM – Naval Architect Ronald Hagenaar heard the penny drop when he was working on his house. “I was making my house ‘greener,’” he says today, “but not my work!” Soon, the Queens Yacht Design founder was working on his 11.4m E-Hybrid 36, an electrically powered motor yacht.

“We must choose electric over diesel. In tenders and larger craft,” says Hagenaar. He leads by example. His first polyester E-Hybrid 36 (65 kW. Max speed: 10,5 kn.) will soon be built.

Hagenaar targets boaters who love green sailing and innovation. He says his boat will enable the rental sector to position itself as a clean industry. Hagenaar sees many industries turning their backs on fossil fuels, but the boating sector is an outlier. “There is a growing acceptance of electric propulsion in smaller yachts, but diesel remains the norm in large craft. Yet electric engines are not the problem. That’s proven technology. The problem is battery capacity and energy generation.”

Consumers find range important and electric engines expensive.

But range, says Hagenaar, is about battery capacity and sailing conducts. “In making my E-Hybrid 36 calculations,” he adds, “I assumed this daily sailing pattern: a total of 30 minutes at top speed, 3 non-active hours and cruising speed the rest of the day.”
Under that scenario, says Hagenaar, “a 60kWh battery suffices making an 80 kWh or 100kWh engines optional. Owners can choose for a range extender or a small diesel generator for extra power. Solar panels can handle ‘hotel’ power.”

Hagenaar is partial to “the traditional boat look with modern touches provided these don’t make the craft too trendy.”

He gave the E-Hybrid 36 a flared bow and sides and a rounded transom with an integrated swimming platform. The helm station windshield is glued to inside styles. Life onboard happens mostly in the one-level cockpit and wheelhouse. The galley has also been placed upstairs. The helm station can be covered.

Up front below deck is a seating area that turns into a double bed. There are closets and a separate shower area. The engine and battery consoles are under the helm station floor. There is no engine box. No noise. No vibration. No emission fumes.

Hagenaar came to his hybrid project after 25 years of running Archimedes Naval Architects, a Dutch studio that worked on yacht and commercial projects. As his focus shifted to sustainable work, he founded Queens Yacht Design. It has to date worked on electric tenders and the 36ft hybrid cabin cruiser.
