Custom Line is adding a shiny new flagship to its famous Navetta line.

The Italian yard, which is helmed by the Ferretti Group, unveiled a new superyacht model on Monday that will be forged entirely from aluminum. Dubbed the “aluminum dream,” the Navetta 50 will be the first Custom Line model to be built from the lightweight metal. (Since opening in 1996, the yard has primarily used fiberglass.)

Penned by Filippo Salvetti, the newcomer spans 164 feet and sports a sleek, displacement hull. The aluminum construction promises to reduce the vessel’s fuel consumption by about 10 to 15 percent compared to a traditional steel vessel of the same size and volume.

Speaking of size, the Navetta 50 has an interior volume of less than 500 GT yet promises plenty of space onboard. Spread across four decks, the vessel has a generous layout that, quite unusually, revolves around the owner’s suite in the bow. Fitted with floor-to-ceiling windows, it offers direct access to a large private terrace and a “sunset solarium.” Elsewhere, there are four guest cabins on the lower deck and accommodation for nine crew.

The interior, designed by Antonio Citterio Patricia Viel, features extensive glazing to connect the indoors to the out and “reflective surfaces that give the sensation of being on an island,” according to the yard. The decor and furnishings showcase a range of eco-friendly materials, including natural hides and leathers, a sustainable walnut paneling called Alpi Lignum and other recycled fabrics.

Outside, meanwhile, there’s a beach club and a large private lounge on the main deck aft that are connected by a rectangular pool in the stern. At the opposite end, the spectacular sun deck can be equipped with a Jacuzzi and solarium. It also features a dining area and an American bar.
