Design and Construction
The SEVENTY 7 draws on a deep well of French multihull expertise. Naval architecture comes from VPLP Design and Marc Van Peteghem, while the elegant interior is the work of Massimo Gino of Italian Nauta Design and the exterior styling is attributed to Patrick Le Quément, as boats.com reported anchor. Construction was handled by CNB, a division of Groupe Beneteau, and the superyacht knowledge of CNB was brought to bear in building the boat, according to Multihulls World anchor. The result is a vessel the builder describes as exemplary of its savoir-faire, and one that is entirely customizable so each living space can be made to feel personal. The deck is surrounded by Lagoon's signature vertical windows, and an electrically opening wide mirrored sliding-glass door reveals the cavernous interior main deck.
Rig and Handling
A 120-foot carbon mast carries a square-top main whose foot sits more than 20 feet above the waterline, set in a triple-spreader rig that testers found fairly manageable anchor. Three headsails on hydraulic furlers are offered, and five Harken winches serve the working cockpit, where helm stations sit forward and somewhat separate. Under sail she will reach 12 knots on a beam reach in a 20-knot breeze, while under power the approximate cruising speed is 9.2 knots. Standard propulsion is a pair of 180 HP diesels, though the first hull was upgraded with 230 HP John Deere engines on V-shafts. The builder expects that whether privately owned or chartered, the model will always carry professional crew aboard.
Accommodations
The social deck plan is generous. The aft cockpit spans 430 square feet with seating for 20, and a curved staircase in the port forward corner rises to the flybridge, where a fiberglass hardtop shelters most of the aft lounge and an optional hot tub, with an outdoor galley module to serve the crew. A forward cockpit holds two L-shaped settees. Inside, the main deck centers on a dining table to port with banquette and free-standing chairs for eight, a U-shaped settee opposite, and a central bar wrapping the mast, with an inside helm station carrying twin B&G displays. The starboard forward corner is given to an owner's private saloon. Below, the semi-custom lower deck runs from three to five cabins plus crew quarters; the port hull cabins can become a massage room, theater, playroom, or conference room. The master stateroom forward in the starboard hull occupies 377 square feet with a king bed, walk-in closet, desk, sofa, and double-vanity head, plus a folding personal veranda over 30 square feet and a hidden hydraulic door that opens to a teak beach. A galley with crew dining area completes the picture.
Known Issues
Testers aboard the first hull noted that the grey oak Wenge flooring was extremely slippery anchor. No other defects or structural concerns appear in the reviewed material.
The Verdict
The SEVENTY 7 is an excellent long-distance cruising boat designed so each person aboard enjoys personal space, and its scale and customization place it in a rare band: series-built yet superyacht-grade. The combination of VPLP naval architecture, Nauta interiors, and CNB construction delivers a stable, voluminous platform with professional-crew infrastructure throughout. The only flagged shortcoming is a practical one aboard the debut hull rather than a systemic fault.
