Across fourteen Sunreef models, there is exactly one where the shipyard publishes the electric specification as the specification rather than as an alternative to a diesel one. It is this boat.
The Two Numbers Nobody Else Gets
The Sunreef 100 Sail NEXT's specification block leads with 2 × 180 kW main engines and a solar array rated up to 45.1 kWp. No fuel capacity is published at all.
That matters more than it sounds. Everywhere else in Sunreef's range you are shown the concept of the Eco version and the hard numbers of the classic diesel one. Here you are given the electric package as the primary figure, which tells you which boat the engineering department is proudest of and which one it considers finished.
For scale, 45.1 kWp is roughly the peak output of a large commercial rooftop installation, carried on a hull that is also generating power from its propellers whenever it is sailing.
Who It's For
This is a superyacht-scale sailing catamaran at 28.65 m (94 ft) overall on a 12.80 m (42 ft) beam — the widest boat in the fourteen models we cover. It is a professional-crew yacht without qualification.
Buy it if the solar-electric argument is the reason you are looking at Sunreef at all, and you want the model where the shipyard commits to published figures for it. Buy it if you need superyacht accommodation on a shallow-draft multihull.
Design and Layout
Sunreef does not publish a living-space figure for the 100 Sail NEXT, but volume is not the constraint on a 29-metre hull with 12.8 metres of beam. 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 en-suite guest suites, and a separate crew area with its own access and galley.
Water capacity is 1,600 l. No cabin or head count is published.
Filed Under Sailing, Hosted Under Superyachts
One point of confusion worth clearing up. The 100 Eco's page lives on Sunreef's superyacht website, which makes it look like part of the superyacht range. It is not.
Sunreef's own superyacht range page does not list the model. Its electric sailing range page does, as the Sunreef 100 NEXT, alongside the 50, 60, 70 and 80. The hosting domain is a consequence of how the shipyard splits its websites, not a product classification.
Sunreef also builds a separate Sunreef 100 Infinity, which is a different model in its own range, and a 100 Sunreef Power. Three quite different boats sharing a length.
What Sunreef Does Not Tell You
Sunreef publishes no speed figure for any boat in its current range. No top speed, no cruise speed, no range — not on this model and not on any of the other thirteen we cover. That is unusual. Most yards at this level publish at least a cruise figure, and several publish full performance tables.
We have left those rows empty on the specification table rather than filling them with an estimate. If a broker or a listing hands you a precise Sunreef speed, ask where it came from, because it did not come from the shipyard.
The same applies to displacement, which Sunreef publishes for nothing in the range, and to draft, which it publishes for only three of the fourteen models. Get the numbers you need in writing before you sign a build contract. Sunreef will provide them — they simply are not on the website.
Where to Start
The 100 Eco is the boat that argues Sunreef's case best, because it is the one where the shipyard puts the electric numbers on the table instead of describing them.
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.
