If someone asked which Sunreef to buy and told me nothing else about themselves, I would say the 70. It is the smallest boat in the sailing range that can genuinely leave and stay gone.
Who It's For
The Sunreef 70 Sail NEXT is for the owner who intends to make passages and then live at the far end of them. Sunreef publishes 21.64 m (71 ft) overall on a 10.85 m (35 ft 7 in) beam, CE design category A, and 287 m² of living space.
The specification that matters most is not on the headline: 1,600 l of water, double what the 50 and 60 carry. That is the practical difference between a boat that visits anchorages and a boat that lives in them.
The Rig Is the Charging System
A 160 m² mainsail with a 120 m² genoa is a serious sail plan, and on an Eco build it is doing two jobs. It moves the boat, and it charges it — hydrogeneration recovers power from the propellers whenever the boat is sailing, which on a rig this size is not a token contribution.
That is the argument for choosing a sailing catamaran over a power one if the Eco package is what you are buying. A power catamaran's solar array charges when the sun is up. A sailing catamaran's charges when the sun is up and whenever the boat is moving.
The classic version of this hull runs 2 × 175 hp to 2 × 225 hp diesels.
Design and Layout
Two hundred and eighty-seven square metres across two hulls, a full-beam saloon and the cockpit. The 70 is the size where Sunreef's bespoke model stops being a nice idea and becomes the reason to buy — there is enough volume to make genuinely different layouts work rather than shuffling the same four cabins between two hulls.
The NEXT saloon design opens the interior aft into the cockpit and forward onto the bow terrace. Sunreef publishes no cabin or head count; every 70 is drawn to its owner's brief, so the general arrangement is part of the contract.
The Decision to Make at Contract
Sunreef specifies the 70's fuel as a single tank between 2,000 l and 4,000 l. That is a two-times spread, and it encodes a choice: are you building a boat that sails and occasionally motors, or the reverse?
Both are legitimate. Neither is reversible cheaply. Make the decision deliberately rather than letting it be made for you by whatever the yard is building that month.
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 70 Eco is the best-balanced boat in Sunreef's sailing range. It has the tankage and the sail area to make the off-grid argument stand on its own, at a size a small crew can still handle.
Step up to the 80 or 100 if you want more solar roof and more accommodation and are already committed to a professional programme. Step down to the 60 if you want to keep the boat closer to owner-operable.
