HS 80 カタマラン

Buying HS 80 is not buying a yacht that happens to be efficient, it is buying a different daily rhythm aboard. Hystream built her around hydrogen-electric propulsion, bifacial solar panels and solid-state energy storage, and delivered her in 2025 as a working answer to what a zero-emission motor yacht can look like. For a buyer, the draw is less about the fuel dock and more about power drawn from the sun and stored hydrogen rather than diesel.

Build and provenance

She is a monohull motor yacht from Hystream, built on a displacement hull rather than a planing one, which suits a boat designed to run efficiently rather than fast. At 25 metres, 82 feet, she has an 11.5-metre beam and a 1-metre draught. Her solar panels gather light from both faces of each panel, not just the top, adding to the power she makes without a trip to a fuel berth.

Layout and accommodation

Eight guests sleep in four cabins, with a crew of four aboard to run both the yacht and her energy systems. The interior favours a modern finish chosen with sustainability in view rather than heavy stone or lacquered surfaces, in keeping with a boat built around an idea rather than tradition.

Performance and engineering

Propulsion is hybrid: an electric drive handles most running, backed by a diesel engine for higher speeds and extended range. She cruises at 8 knots and reaches 16 at full power, speeds suited to endurance and quiet running rather than covering distance fast. Navigation software plots the route and watches for other traffic, working alongside the crew rather than in place of them.

On deck and at anchor

A beach club opens at the stern and a spa pool sits on deck, so a boat that generates its own power still gives guests the simplest way to spend time on the water.

Where she lies and how to see her

Boatcrowd arranges every viewing of HS 80 in person and attends each one with you. Once an offer is accepted, we bring in the surveyor and set the sea trial before anything is finalised.
