Secretive 50m Feadship superyacht Project 717 enters final outfitting

Feadship's 49.5-metre in-build superyacht Project 717 has entered the final stages of outfitting, according to her central agent Edmiston. Currently under construction at the Feadship De Vries shipyard in Aalsmeer, the Netherlands, the broker announced that all metal works have now been completed and all technical systems have been installed, with the vessel on track for her scheduled delivery in March 2026.

The all-aluminium superyacht, which is listed for sale as Project Fun, has been kept tightly under wraps by the Dutch yard and was last sighted in July 2024 while on transport to Aalsmeer. Outfitting works will continue with all decks currently being prepared for teak laying. Her technical launch is scheduled for November this year.

Exterior design is angular and low-profiled, with Studio De Voogt touches including a vertical bow and a long, narrow strip of glazing across her superstructure. Meanwhile, interiors are the work of American studio Marty Lowe, with the recently released renderings revealing a pale, pared-back aesthetic that incorporates bright lighting and granite-esque panelling. Naval architecture is owed to Feadship De Voogt Naval Architects.

Accommodation is for 10 guests across five cabins, including a full-beam owner's suite on the main deck complete with floor-to-ceiling windows, walk-in wardrobe, marble en suite, private study and lounge seating. There are further quarters for up to eight crew, with all cabins located on the lower deck.

Major social hubs include the main deck aft, which spills onto the beach club with a large glass-fronted Jacuzzi and fold-down bulwarks, and the sundeck, in which the helm station is backed by a 14-person dining table and a sofa lounge. Other design highlights include a sequestered, formal dining area and storage for a Williams Dieseljet 625 and a Williams Dieseljet 450 tender.

Edmiston also revealed that the 499GT yacht will harbour a diesel-electric propulsion system combined with Schottel Azimuthing drives and a battery bank for peak shaving. She is expected to reach a top speed of 15 knots, with a range of 4,000 nautical miles at a cruising speed of 10 knots. She will also be "fully capable" of running on HVO fuel.

The yacht for sale is offered as "a turn-key package", with a "dedicated full-time project manager" overseeing the build to delivery.

Edmiston has managed several key Feadship builds in the last year, including the 75.8-metre One and the 118.8-metre Breakthrough, the world's first fuel-cell superyacht, which is currently awaiting delivery to a new owner.
