ISA's 38.8m Viper 130 Fast Naan Launches, Second Hull On Spec

Why is ISA's new Viper 130 called Fast Naan?

Fast Naan is named for Big Naan, the 42-metre Columbus Crossover her owner already had, a private joke that also ties two brands under the same Italian shipbuilding group together in one hull's name.

ISA Yachts, a brand of Palumbo Superyachts, launched the 38.8-metre Fast Naan at the yard's Ancona facility on 25 August 2026, in a ceremony attended by her owner, his guests and the shipyard team. She is the first unit off ISA's Viper 130 platform, a GRP planing model unveiled in May 2024, and she sold to an American client roughly two months after that unveiling, before a single hull had been cut. The sale was brokered by Zarpo Yachts, which introduced the buyer to ISA. Fast Naan now moves straight into her sea trial programme, with a world debut booked at the Cannes Yachting Festival in September, followed by the Monaco Yacht Show days later.

The name is not incidental. Zarpo Yachts had previously handled the sale of Big Naan, a 42-metre Columbus Crossover, and Columbus is ISA's sister brand within Palumbo Superyachts, alongside Extra and Mondomarine. An owner moving from a Columbus to an ISA, through the same broker, and carrying his old yacht's name into the new one is the clearest kind of evidence a yard can get that a client trusts the group enough to buy again inside it, and it is the sort of repeat-custom detail that never shows up in a spec sheet.

How fast is the ISA Viper 130, and what powers it?

Fast Naan is rated to 33 knots flat out and 26 knots cruising, on three MAN V12X engines at 2,200 hp apiece, driving two MJP waterjets plus a central MJP booster.

The hull and superstructure are composite with carbon fibre, built as a true planing form rather than the semi-displacement shape more common at this length. Exterior and interior design is credited to Italian designer Fulvio De Simoni, working with ISA's in-house team on the outside and alone on the interior, while the naval architecture was developed jointly by the shipyard and Studio Ing. Arnaboldi. BOAT International's launch report and Megayacht News's own coverage of the hull both put the top speed at 33 knots, which is the figure this desk is using; a wider web summary circulating since August put it at 35 knots, but that number traces to no named primary source and is dropped here in favour of the two that agree.

A three-engine, twin-waterjet-plus-booster layout is a heavier and more complex driveline than the twin-engine norm on a planing yacht this size, and it exists to buy acceleration and top-end speed rather than range or fuel economy. None of these figures have yet been checked by an outside sea trial: they are the yard's own numbers, repeated at launch, and Fast Naan's actual performance in open water will not be independently reported until she has done more running than a ceremony in the Ancona basin.

What is the accommodation and deck layout on the Viper 130?

Fast Naan sleeps up to 11 guests across five lower-deck cabins and carries six crew, built around a cockpit split into three distinct zones rather than the single aft lounge most 38-metre yachts settle for.

The owner's suite has two bathrooms, and the four guest cabins split two double and two twin-plus-Pullman, all en suite. Six crew sleep in three en suite cabins, kept away from the guest areas. The main deck carries a second bar and a saloon arranged into two separate lounge areas with semi-circular sofas and a ten-seat table, lit by floor-to-ceiling windows and reached by a single port-side walkway to the bow so guest areas are never crossed by crew moving fore and aft. The wheelhouse also sits on the main deck rather than a level up, which is a Viper-line choice that trades a captain's sightline height for lower windage and a cleaner profile.

The cockpit itself is the standout: a lounge zone with sofa seating, a coffee table and side-opening balconies; a separate al fresco dining space for ten; and a beach club fitted with a multifunctional transformer that can be reconfigured for swimming, lounging or tender access. A combined galley and bar behind it has an electrically switchable-glass partition, so the space can show off the cooking or close it off for a formal service. Up on the sundeck, sheltered by a carbon-fibre hardtop, there is a second helm station, two sunpads aft, another bar and lounge, and a further ten-seat table; the bow adds a circular pool and sunloungers. A five-metre tender stows in a starboard-side garage.

Is ISA Yachts building more Viper 130s?

ISA started construction of a second, unsold Viper 130 in February 2026, on speculation rather than to a buyer's order, with delivery scheduled for March 2028.

A yard cutting steel, or in this case laying up composite, on a semi-custom hull with nobody yet committed to pay for it is a direct bet on resale demand, funded from the yard's own balance sheet rather than a client's stage payments. The gap between that February 2026 start and a March 2028 delivery, over two years, is the real lead time a buyer ordering a Viper 130 today should expect, regardless of how quickly Fast Naan herself sold off renderings.

The bet sits inside a busier moment for ISA as a whole. BOATPro's own tracking puts 14 yachts currently under development at the yard, and ISA has just delivered the flagship of an entirely different model line, the Gran Turismo 67M Sea Raider X, which will stand alongside Fast Naan at the Monaco Yacht Show in September. Two new models reaching the water and the show circuit in the same season, from a yard that is also willing to build a semi-custom hull with no buyer attached, reads as a shipyard scaling up rather than one testing a single design and waiting to see what happens.

What does ISA Yachts not say about the Viper 130?

ISA has not disclosed a price for Fast Naan or for the Viper 130 line generally, and no independent sea trial or ownership experience exists yet because the yacht is days old.

Semi-custom Italian builders at this end of the market routinely sell without a published base price, negotiating directly with a buyer's broker instead, and ISA and Palumbo Superyachts follow that pattern here: nothing in the launch coverage, the yard's own materials or BOATPro's tracking gives a figure for what Fast Naan or her sister hull actually cost. For a buyer trying to benchmark a 38-metre planing yacht against alternatives, that silence means the only real data point available is asking the yard directly, through a broker, and comparing whatever number comes back against completed sales of similar-sized GRP planing yachts from other builders once those become public.

The same is true of performance and ownership experience: every figure in this story, from the 33-knot top speed to the cabin count, comes from the yard and the launch-day trade coverage, because there has not yet been time for anything else to exist. No independent sea trial has been published, and no owner, charter guest or captain has spoken publicly about how she actually handles or lives. That is normal for a yacht five months from her Cannes debut, not a defect in the reporting, but it is worth saying plainly rather than dressing up a launch photo as a verdict on how she performs.
