You want the yard's largest sailing catamaran with a solar array big enough that Sunreef is willing to put a number on it. That is the Sunreef 100 Sail NEXT with the Eco-Option.
Part of the Sunreef Sail NEXT series — see how owners step up through the lineup.


The 100 Eco is the only boat in Sunreef's entire fourteen-model lineup where the yard publishes the two numbers that matter to an electric boat: 2 × 180 kW of motor and a solar array up to 45.1 kWp. Everywhere else in the range you are told the concept and shown the classic diesel figures. Here you are given the electric specification as the specification. That tells you which boat the engineering department is proudest of.
What you will not find is a fuel capacity, and I do not think that is an oversight. This is the one Sunreef where the electric drivetrain is the primary system rather than the alternative to it.
Ninety-four feet on a forty-two-foot beam is a very large yacht and a professional-crew boat without qualification. But if the reason you are buying a Sunreef is the solar argument, this is the boat that argues it best.

The Sunreef 100 Sail NEXT is the largest catamaran in the yard's sailing range. Sunreef publishes 28.65 m (94 ft) overall on a 12.80 m (42 ft) beam, with water capacity of 1,600 l.
Uniquely across the fourteen models we cover, the 100 Sail NEXT's specification block leads with its electric package rather than a diesel alternative: main engines of 2 × 180 kW and a solar array rated up to 45.1 kWp. No fuel capacity is published.
Sunreef's sailing range page lists the boat as the "Sunreef 100 NEXT". Although its page is hosted on the yard's superyacht site, Sunreef files it under Sailing Yachts, not Superyachts — the superyacht range page does not list it.
Sunreef publishes no speed, cruise or range figure for the 100 Sail NEXT, so those rows are empty.
What it does publish is the electric specification, and this is the only model in the range where it does so as the primary figure: 2 × 180 kW motors and up to 45.1 kWp of solar. For context, that array is roughly the peak output of a large residential rooftop system, carried on a hull that is also generating power from its propellers whenever it is sailing.
No fuel capacity is published for the 100 Sail NEXT. Draft is not published either.
Sunreef does not publish a living-space figure for the 100 Sail NEXT, but the 12.80 m beam is the widest in the fourteen models we cover and the hull is nearly 29 m long. Volume is not the constraint here.
As with every Sunreef, the interior is drawn to the owner's brief. At this size that usually means a full-beam owner's deck, multiple guest suites with en-suite heads, and a separate crew area with its own access and galley.
No cabin or head count is published. On a boat built entirely to order, the general arrangement is contract documentation rather than a brochure specification.
The 100 Eco is a superyacht-scale sailing catamaran, and it competes with a very short list. Most yards that build multihulls stop well before 94 feet; most yards that build at 94 feet build monohulls.
Sunreef's position rests on the in-house solar and electric engineering, and the 100 is where it puts the numbers on the table. The yard also builds a Sunreef 100 Infinity, a separate model in its own range, and the 100 Sunreef Power — three quite different boats sharing a length.
Against the 80 Sail NEXT this is more of everything, with a crew requirement to match.
Buy the 100 Sail NEXT if the solar-electric argument is the reason you are buying a Sunreef at all, and you want the model where the yard commits to published figures for it. It is also the choice if you need superyacht-scale accommodation on a shallow-draft multihull platform.
Step down to the 80 Sail NEXT if you want the same philosophy at a size a smaller crew can run. Step across to the 100 Sunreef Power if you want the volume without the rig. Look elsewhere if you need published speed or range.
Up to 45.1 kWp, which Sunreef publishes on the model's own specification block. This is the only boat in Sunreef's fourteen-model lineup where the yard commits to a solar figure in print. It is paired with main engines of 2 × 180 kW, and no fuel capacity is published for the model — the electric drivetrain is the primary system here rather than the alternative to one.
Sunreef files it under Sailing Yachts. Its page is hosted on the shipyard's superyacht website, which is a consequence of how Sunreef splits its sites rather than a product classification — the yard's superyacht range page does not list the model, while its electric sailing range page does, as the Sunreef 100 NEXT. At 28.65 m (94 ft) it is the largest boat in that range.
