The Otam 80 GTS is a 25.75 metre open sportsyacht that distils the yard’s fast-cruiser philosophy into a tighter, more agile package than the flagship 90. Built on a deep-V hull with a 21 degree deadrise and laid up in Aramat and GRP or full Kevlar, she is engineered first for speed: twin MTU diesels of 2,600 horsepower on Arneson surface drives push her to a remarkable 48 knots, with a 40 knot cruise.
For owners who prefer a softer ride and lower running costs, Otam offers a Caterpillar C32 package of 1,925 horsepower that still delivers 40 knots. Either way the 80 GTS behaves like a much smaller boat under throttle, the surface drives and light composite structure giving her sharp acceleration and a dry, planted feel at speed.
The open GTS layout keeps the deck clean and social, with a long cockpit, convertible sunpads and a tender garage aft that swallows a 3.95 metre dinghy. Below, a semi-custom interior sleeps guests in a configuration set by the owner, so no two 80 GTS hulls are identical.
This is a focused, hand-built Italian sportsyacht for an owner who values pace, agility and individuality over sheer volume, and who wants the open-cockpit thrill the GTS name has always stood for.

Performance is the whole point of the 80 GTS. In MTU form, twin 2,600 horsepower diesels on Arneson ASD 15L surface drives take her to 48 knots flat out and a 40 knot cruise, extraordinary figures for a 25.75 metre yacht. A Caterpillar C32 ACERT package of 1,925 horsepower is the alternative, trading the top end for a softer ride and lower fuel burn while still holding 40 knots. The deep-V hull carries a 21 degree deadrise for a clean entry in a chop, and the Aramat and GRP or Kevlar layup keeps weight low so the surface drives can do their work. The result is sharp acceleration, a dry ride and the kind of agility usually reserved for boats half her length.
Giuseppe Bagnardi gives the 80 GTS the lean, dark-hulled aggression that defines the open end of the Otam range. The profile is low and purposeful, with a long foredeck, raked stem and open cockpit that keeps the lines clean and uninterrupted. Without a hard top the yacht reads as pure sportsboat, all horizontal speed and minimal superstructure. A tender garage aft hides a 3.95 metre dinghy and keeps the deck uncluttered, while the transom opens to a bathing platform at the stern. Deep bulwarks and flush detailing reinforce the focus on going fast. It is a restrained, muscular exterior that puts performance ahead of fashion, exactly as Otam intends.
Below the open deck, the 80 GTS offers a semi-custom interior typically arranged for six guests in 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 rather than ornate, in keeping with the yacht’s sporting character. Natural light comes through hull and superstructure glazing, and materials are chosen for a light, modern feel. Because every 80 GTS is specified individually, cabin count, berth arrangement and finishes are agreed during the build, so the accommodation reflects how each owner intends to use the boat, whether for fast day runs or occasional overnights aboard.
The open cockpit is where the 80 GTS lives. A long, uncluttered deck runs aft from the helm with convertible seating and sunpads that turn the space from a fast-driving station into a social lounge at anchor. Without a hard top the whole area is open to the sky, giving the boat its sense of speed and freedom. The bathing platform and garage at the stern make launching the tender and getting into the water straightforward, and the foredeck offers a quieter sunbathing spot forward. For a performance sportsyacht the 80 GTS makes the most of its deck, built around sun, speed and easy access to the sea rather than enclosed volume.
The 80 GTS is a hand-built, semi-custom yacht, so ownership starts with a conversation about specification: engine package, interior layout, hull layup and finish are all agreed with the yard. The two engine options let owners balance outright speed against running costs, and the composite construction is chosen for performance and longevity. As one of a small range rather than a series model, she offers real individuality and Otam’s engineering pedigree. Running a 48 knot sportsyacht carries its costs, but the payoff is performance few rivals match at this length. For an owner who wants a focused, open Italian sportsyacht with a tailored interior and genuine pace, the 80 GTS is a compelling choice.
