Flagship of the electric power line

The 100 Power Eco sits at the top of Sunreef's electric power catamaran range, the fullest expression of the yard's zero-emission ambition. At 28.65 metres it is a true superyacht with the deck and interior volume to match. It shows what an owner can now expect from silent, solar-assisted cruising at this scale. Everything below it in the range borrows from its engineering. It is the boat that proves a full superyacht can run clean without giving up any comfort.

Sunreef delivers the 100 Power as a fully electric Eco yacht, and the specification is serious. Two electric motors of 360 kW draw on a battery bank of 770 kWh. The hull, superstructure and bimini carry more than 240 square metres of integrated solar with a generation capacity up to 46 kWp. That combination makes genuine zero-emission cruising a daily reality, not a demonstration. For an owner who wants to lead on sustainability, the numbers here are the argument in full.

Design and deck architecture

The 100 Power uses its 13.5-metre beam to build deck spaces on a scale few motor yachts can rival. The flybridge is a destination in its own right, with dining, sunbathing and a bar under the sun. The aft platform and fold-down terraces open a broad beach club at the waterline. Owners shape these spaces to host large parties or to keep quiet corners for two. The sheer width means a full guest list can gather on one deck without ever feeling packed in.

The styling is confident and modern, low in the water with the muscular Sunreef stance. Custom paint and detailing give each 100 its own identity. The foredeck adds a further private lounge away from the main social decks. The exterior is engineered for a life lived largely in the open air. Owners who split their time between hosting and hiding away find both moods built into the deck plan.

The electric flagship: twin 360 kW motors, a 770 kWh bank, 240 square metres of solar

Interior and accommodation

Inside, the 100 offers apartment-scale rooms and a main deck that flows out to the aft cockpit through vast glazing. The layout typically allows up to two guest cabins per hull, with a full-beam owner's suite as a centrepiece. Sunreef's artisans finish the interior in the owner's chosen materials to a bespoke brief. Natural light and sea views run through every principal space. The full-beam master sits at the heart of the yacht as a private residence within the superyacht.

Systems, storage and tankage are scaled for long, independent cruising. The galley and crew areas support full professional service. Climate control is engineered to work within the electric energy budget. The interior mood is expansive, refined and calm. The layout keeps owner, guest and crew movement separate, so the yacht feels private even with a full complement aboard.

The electric powertrain

The heart of the 100 Power Eco is its electric drivetrain, with twin 360 kW motors fed by a 770 kWh battery bank. The solar skin harvests up to 46 kWp across more than 240 square metres of integrated surface. The yacht moves and holds anchor without vibration, engine noise or local emissions. The hotel load draws from the battery, so silence extends to the whole boat. To hold a busy bay in total quiet, on a superyacht of this size, is the headline the 100 delivers.

This is mature technology carried down from the yard's largest projects, not a prototype. Sunreef builds the composite structure in house for a light, stiff hull that suits electric propulsion. The system is engineered to recharge and to keep real cruising range on the table. The aim is a superyacht that runs clean and quiet every day. That in-house composite build keeps the weight in check, which is what makes the range figures achievable.

The owner it suits

The 100 Power Eco suits the owner who wants a flagship-class motor catamaran that makes no compromise on its green credentials. It rewards those who host at scale and value silence at anchor above almost everything. Buyers who want to lead on sustainability without giving up superyacht comfort will find their yacht here. It is a statement of where luxury boating is heading. For an owner ready for a full crew, it is the electric summit of the production range.

It also stands as a headline charter asset, where silent electric cruising sells at the very top of the market. The volume, the beach club and the flybridge make it a natural host. For an owner ready for a full crew and a true superyacht, this is the electric summit of the range. Life aboard is grand, quiet and genuinely self-sufficient. Owners who want the boat to work when they are ashore will find strong demand for a superyacht that runs on the sun.

Who it is for: Owners who want a flagship motor catamaran that hosts at scale and cruises in genuine zero-emission silence.
