Otam improves efficiency

High-performance boatbuilder Otam has debuted the third 70 HT, which sports several differences including improved fuel efficiency at high speeds.

The third unit of Otam’s 70 HT cruising motor yacht has made its international debut at the 2023 Cannes Yachting Festival, which ran from September 12 to 17 2023.

The Otam 70 HT is designed by Giuseppe Bagnardi of BG Design Firm with sportscar-like hull lines by Umberto Tagliavini Marine Design. On request of the owner, Otam was able to improve the unit’s fuel efficiency at speeds in excess of 40 knots, thanks in part to the lightweight, rigid construction in Aramat, Kevlar and carbon fibre.

The 22-metre-long vessel has the largest rigid sliding roof in its class, and a long list of technical modifications made for the owner-operator, who will be using the boat all year round.

The launch comes as Italian high-performance boatbuilder Otam prepares to mark its 70th anniversary next year.


“This boat belongs to a technically minded owner-operator who likes to use his yacht year-round in all sea conditions,” says Matteo Belardinelli, Otam’s sales and communication manager.

“His choice of Otam was no coincidence. Aware of our bespoke approach, he came to us because he knew we could deliver on his detailed list of technical and aesthetic requests.

“Because he uses the boat 12 months a year, for example, he wanted heating as well as air conditioning and heated floors in the bathrooms.”

Another special request was moving the generators further aft, which involved a detailed study by the in-house engineering team of the weight distribution to ensure that handling and performance were not affected. The owner also asked for a co-pilot station equipped with exactly the same navigation and monitoring equipment as the main helm station.

Like the first and second hulls in the 70 HT series, the owner has chosen the version without a tender garage and with side access to the aft cockpit. But there are numerous differences: the owner wanted the largest rigid sliding rooftop possible for natural ventilation both at anchor and underway and requested the marble countertops be cut from the same block of stone so the veining is constant throughout the yacht.

On the lower deck are three cabins, a galley and crew quarters, with independent access from the foredeck. On the main deck, there is a dinette and a second galley.

“Like every Otam, the Otam 70 HT is designed to exceed the expectations of our demanding owners,” adds Belardinelli.

“Without exception, they are looking for something unique and exclusive, and that means we’re always pushing our own boundaries. This latest delivery is yet another example of our mission to build extraordinary, high-performance yachts that are tailored to every client’s personal requirements.”
