You want the 60 Power's deck plan with the tankage to leave the marina behind for a fortnight. The Sunreef 70 Power NEXT is the middle of the power range.

Quick Verdict

  • Water capacity doubles to 1,600 l over the 60 Power, and fuel runs to 8,000 l — this is where the range starts to support real time away from a dock
  • A tighter engine band than the 60 at 2 × 300 hp to 2 × 600 hp, which makes it the more coherently specified boat
  • Sunreef's English-language page for this model currently returns an error while the boat stays listed in the yard's own navigation and sitemap; the figures here come from the other language editions

Our Take

The 70 Power is the boat that turns the 60's deck plan into something you can genuinely go away in. Water doubles to 1,600 litres, fuel runs to 8,000, and the beam goes out to 11.35 metres. It is the least compromised boat in the power range at a size two crew can still handle.

There is a wrinkle worth knowing about, and it is Sunreef's, not ours: the English-language page for this model currently returns a 404, even though the boat is listed on the yard's own power range page, in its mega-menu and in its sitemap. The specification above is Sunreef's own, read from the other language editions of the same page, which are all live. The model is current. The page is broken.

Engine range is narrower here than on the 60 — 300 to 600 hp a side rather than 300 to 850. That is a more coherent boat.

Sunreef 70 Power NEXT ( Eco-Option ) Overview

The Sunreef 70 Power NEXT sits between the 60 and the 80 in the yard's power catamaran range. Sunreef publishes 21.3 m (69 ft 11 in) overall on an 11.35 m beam, CE design category A, 1,600 l of water and 4,000–8,000 l of fuel.

The doubling of water capacity over the 60 Power is the practical difference between the two boats: this is the length at which the range starts to support extended time away from a dock.

Sunreef's power range page lists the boat as the "70 Sunreef Power NEXT". Note that the yard's English-language page for this model currently returns a 404 while remaining listed in its own navigation and sitemap; the figures above are taken from the other language editions of the same page.

Performance & Handling

Sunreef publishes no speed, cruise or range figure for the Sunreef 70 Power NEXT, so those rows are empty.

The classic version is specified as 2 × 300 hp to 2 × 600 hp — a tighter band than the 60 Power's. The Eco version substitutes Sunreef's solar-electric package, with the yard's own composite-integrated panels and battery bank; no motor output or battery capacity is published for it.

Draft is not published. Given that this is a shallow-draft platform by design, it is worth asking Sunreef for the figure directly.

Interior & Accommodations

An 11.35 m beam on a 21.3 m hull produces a very large deck plan: a full-beam aft cockpit, a flybridge, and hull volumes deep enough to carry both guest and crew accommodation without one intruding on the other.

As across the range, layouts are drawn to the owner's brief rather than picked from options. The 1,600 l water capacity is the specification that shapes how the boat gets used — it supports a full complement aboard for materially longer than the 60 Power can.

Sunreef publishes no cabin or head count for the 70 Power.

Market Position

At 70 feet the Sunreef power catamaran competes with flybridge monohulls of similar length that offer far less deck area and much more draft, and with a small number of custom multihull builders.

The Eco package remains the differentiator: solar panels designed and built in-house and integrated into the composite structure rather than added to it.

Against the 80 Power the 70 gives up substantial tankage and volume. Against the 70 Sail NEXT sailing catamaran it trades the rig and hydrogeneration for a flybridge and pace.

Who the 70 Power NEXT ( Eco-Option ) Is For

Buy the Sunreef 70 Power NEXT if you want the power range's deck plan with the water and fuel to actually leave the dock behind. It is the best-balanced boat in the range at a size that does not automatically require a large crew.

Step up to the 80 Power for materially more tankage and accommodation. Step down to the 60 Power if berthing and running costs matter more than range. Ask Sunreef directly for the model page — theirs is currently returning an error in English.

Frequently Asked Questions

What are the Sunreef 70 Power NEXT's specifications?

21.3 m (69 ft 11 in) overall on an 11.35 m beam, CE design category A, with 1,600 l of water and 4,000–8,000 l of fuel. The classic version runs 2 × 300 hp to 2 × 600 hp. Those figures come from Sunreef's own specification block, read from the non-English editions of the model page because the English edition currently returns a 404 while the model stays listed in the yard's navigation and sitemap.

How is the 70 Sunreef Power different from the 60?

Water capacity doubles from 800 l to 1,600 l, which is the practical difference between a boat that visits anchorages and one that stays in them. Length goes from 18.3 m to 21.3 m and beam from 10.70 m to 11.35 m. The engine band also narrows — 300 to 600 hp a side rather than 300 to 850 — which makes the 70 a more consistently specified boat.
