Sestante means ‘sextant’ in English, a traditional navigational instrument and a suitably nautical moniker for a thoroughly modern 70m concept by Mulder Design that is destined to become the flagship of the Baglietto fleet.

When Baglietto outlined its new product range at the Monaco and Fort Lauderdale shows, one project in particular raised some eyebrows. To date, the flying seagull brand has focused on the 30-50m size range, but its 70m Sestante concept designed in collaboration with Mulder Design in the Netherlands represents an ambitious step up in size.

“In a rare collaboration with a non-Italian designer, we asked Frank Mulder to create a megayacht concept that would draw inspiration from and preserve Baglietto’s distinctive style, but reinterpret it in a new and innovative way,” says CEO Michele Gavino. “The result is a yacht with masculine yet seductive lines that also oozes cutting-edge technology and performance.”

“Our approach is to focus on the big picture, methodically and repeatedly going through every element of the process,” says Frank Mulder. “Each part is as important as the other and everything is interconnected – from a great-looking exterior style to the performance, seakeeping and engineering.”

It was this holistic approach that attracted the Baglietto team to the Dutch studio when it was looking to introduce a flagship project to the fleet. Beyond

the graceful exterior styling that faithfully retains the Baglietto DNA, the heart of the project and its elevated performance lies in the advanced naval architecture.

The technical platform is based on Mulder’s High Speed Cruising Hull that provides enhanced stability, seaworthiness and efficiency in all weather conditions. By optimising the flow of water using CFD (Computational Fluid Dynamics), the hull design achieves an efficient combination of hull shape, bulbous bow and transom immersion to lower resistance over a wide speed range without the loss of onboard comfort.

“We’ve been working hard on this project since 2016,” said Michel Gavino at the project’s presentation during the Monaco Yacht Show. “At Baglietto we don’t believe in promoting new concepts based simply on the exterior styling and general arrangement. So our in-house technical team also worked closely with Mulder Design to develop the engineering platform and naval architecture.”

Sestante will not only be very efficient at high speeds, but will also shine at long-range cruising speeds. Depending on the power package, top speeds of up to 25 knots and a range of 7,000 nautical miles at 12 knots can be attained. Further fuel efficiency can be achieved by specifying Voith linear jet propulsion combined with hybrid or diesel-electric propulsion.

Naturally, the custom design is not lacking in creature comforts. The master stateroom, for example, features a private deck with Jacuzzi, while the VIP suites enjoys panoramic views from private balconies. There is also a touch-and-go helipad forward and two large tenders can be stowed in the aft garages, one on port side and the other behind the beach lounge.
