The Otam 80 HT is the enclosed-coupe version of the yard’s 80 GTS, a 25.75 metre sportsyacht that pairs the open boat’s 48 knot performance with the shelter of a fixed hard top. She shares the same deep-V hull, drawn by Umberto Tagliavini with a 21 degree deadrise, and the same light Aramat and GRP or full Kevlar construction, so nothing about the performance is lost in adding the roof.
Twin MTU diesels of 2,600 horsepower on Arneson surface drives give a 48 knot top speed and a 40 knot cruise, while a Caterpillar C32 package of 1,925 horsepower offers a calmer, more economical alternative that still reaches 40 knots. The hard top makes the difference in use: the helm and saloon stay protected from sun and spray, extending the cruising season well beyond what the open GTS allows.
The deck keeps Otam’s clean, purposeful look, with a sheltered cockpit, a tender garage aft for a 3.95 metre dinghy and a bathing platform at the stern. Below, a semi-custom interior typically sleeps six in a layout chosen by the owner.
For a buyer who wants the thrill of an Otam sportsyacht but prefers a sheltered, four-season coupe to an open cockpit, the 80 HT is the natural choice in the yard’s 25 metre class.

The 80 HT keeps the full performance of the open GTS. In MTU form, twin 2,600 horsepower diesels on Arneson ASD 15L surface drives deliver 48 knots flat out and a 40 knot cruise, with a Caterpillar C32 ACERT package of 1,925 horsepower as the economical alternative, good for 40 knots. The deep-V hull carries a 21 degree deadrise for a clean, dry ride in a chop, and the Aramat and GRP or Kevlar layup keeps weight low so the surface drives can work efficiently. Adding the hard top costs almost nothing in speed, so the 80 HT runs with the quickest boats of its size while offering shelter the open version cannot. This is genuine 48 knot capability in an all-weather package.
Giuseppe Bagnardi’s exterior keeps the lean Otam profile but adds the defining fixed hard top over the bridge deck, which stretches the coupe lines aft and shelters the helm and cockpit. Large side and roof glazing keep the superstructure visually light, so the yacht reads as sporty rather than top-heavy, and the white hull on the first hull shows the clean, uncluttered styling to good effect. A long foredeck, raked stem and low stance underline the performance intent. A tender garage aft hides a 3.95 metre dinghy, and the transom opens to a bathing platform at the stern. Next to the open 80 GTS, the HT is the more practical, four-season expression of the same fast hull.
Below decks the 80 HT offers a semi-custom interior typically arranged for six guests across a layout set by the owner. The full six metre beam gives the main cabin usable width, and Otam’s joinery is clean and contemporary, with warm timber and quiet detailing seen on the first hull. The hard top brings a practical gain inside as well, sheltering the saloon and upper helm so the bridge deck stays usable in a wider range of conditions. Natural light enters through generous glazing in the superstructure and hull. As every 80 HT is specified individually, cabin count, berth layout and finishes are agreed during the build, so the accommodation suits how each owner intends to cruise.
The sheltered cockpit under the hard top is the 80 HT’s key social space, usable in sun, wind or light rain where the open GTS cockpit is exposed. Seating and a dining area sit aft of the helm, flowing off the main deck saloon through wide glazing. At the stern, the bathing platform and tender garage make swimming and launching the dinghy easy, and a foredeck sunpad gives a quieter spot forward. For a fast coupe the 80 HT offers a well-judged spread of indoor and outdoor living, and the hard top means owners get far more use out of those spaces across the year than an open sportsyacht allows.
Like the rest of the range, the 80 HT is a hand-built, semi-custom yacht, so ownership begins with specification: engine package, interior layout, hull layup and finish are all agreed with the yard. The two engine options balance outright speed against running costs, and the composite construction is chosen for performance and durability. As one of a small range rather than a production model, she offers real individuality and Otam’s engineering pedigree. A 48 knot sportsyacht carries its running costs, but the hard top makes the 80 HT genuinely more usable than an open boat. For an owner who wants a fast, sheltered Italian coupe with a tailored interior, she is a compelling choice in the 25 metre class.
