Oromarine Coupé S13, the sea trial of a maxi RIB that combines boldness and comfort

The Oromarine Coupé S13 is the new interpretation of the maxi RIB according to the Campania-based shipyard: a successful blend of sportiness and refinement, combining the thrust of two powerful outboards with the pursuit of yacht-level comfort. It is a boat designed for those who want more, for those who aim to cruise in style without giving up purebred performance.

With its overall length of 12.45 meters and a hull developed from the experience gained on previous models, the Coupé S13 is a boat that not only stands out for its performance and build quality, but also conveys a strong sense of solidity and control that you can feel the moment you step on board.

The test configuration mounts two Honda V8 350 hp engines, a choice that reflects the project’s philosophy: power managed with balance. This RIB promises fun, as well as comfortable and safe cruising for the whole family. The deck layout is designed to offer spacious and functional areas, capable of accommodating up to 24 people, while also being able to transform, at night, into a small suite on the sea thanks to the below-deck cabin. A concept that makes it perfect both for day outings and for medium-range cruising.

Oromarine Coupé S13 Sea Trial

The sea trial took place in Genoa, on a day when the sea was challenging even for larger hulls: waves between half a meter and one meter and strong wind. In short, ideal conditions to assess the true solidity of the project.

Even at idle speed, the Coupé S13 moves smoothly, with no vibrations. At 600 rpm, you can cruise at 3 knots while consuming just over 5 liters per hour, a sign of excellent hull efficiency. As the revs increase gradually, the boat gets on plane naturally: the minimum planing speed is around 11.5 knots, reached at just under 2,000 rpm, with a neutral trim and no need to adjust the trim tabs.

At 3,000 rpm, we are already in full and stable planing, at about 22 knots, with a total fuel consumption of around 67 liters per hour. The sensations at the helm are immediate: the RIB reacts promptly, maintains course even in crossed waves, and always conveys a strong sense of control. The passage over the waves is soft, never harsh, and even at higher speeds the impact is smoothly absorbed by the hull.

At 4,000 rpm, with the choppy Genoa sea requiring some attention, the GPS reads 30 knots: the feeling remains one of stability. The Coupé S13 cuts through the waves effortlessly, without pitching or skidding. Tight turns are fluid and predictable, and the steering response always remains light.

Pushing further, at 5,600 rpm, the boat reaches the ideal cruising speed of 40 knots, with a total consumption of about 164 liters per hour. It’s the perfect setting for long trips, where comfort and efficiency are best balanced. And for those who want to push the limits, the power of the two Hondas allows you to reach a top speed of 47.8 knots, with trim always clean and stable. Even at this pace, the dominant feeling is one of safety: the boat remains composed, with no annoying pitching, and wave impacts stay smooth.

What impresses the most is how easy the Coupé S13 is to handle: despite the 700 horsepower available, it is never nervous. The hull works progressively, and the steering response is always smooth and linear. Noise levels remain low as well, thanks in part to the bracket, which effectively isolates vibration transmission.

On the way back to the harbor, riding through the waves, the Coupé S13 confirms its balance: a RIB with a sporty soul, yet one that never gives up elegance and comfort.

Oromarine Coupé S13 – Test Data

The Oromarine Coupé S13 in detail

Taut lines and balanced proportions define the profile of the Oromarine Coupé S13. The bow is sharp, with a sleek shape that connects to a deep hull designed to ensure smooth wave penetration and lateral stability even at high speeds. The aluminum bracket with integrated swim platforms is one of the most intelligent solutions of the project: it improves trim and frees up useful space on deck, providing a convenient and functional aft platform.

The cockpit is the heart of life on board. The large C-shaped sofa, upholstered with UV-resistant cushions and featuring an integrated footrest, creates a convivial environment that can be transformed into a dining area or an additional sunbathing space simply by lowering the central table. Beneath the seats, the molded lockers offer generous storage volumes and refined finishes, ideal for extended stays on board. The Seadeck flooring ensures comfort underfoot and contributes to the general impression of relaxed elegance that is perceivable everywhere.

At the bow, a large sunbed takes center stage: wide, protected by the tubes, and seamlessly integrated with the design of the central console. The console itself is one of the standout elements of the project: modern, ergonomic, with a color-matched dashboard, sport steering wheel, and a large tinted windshield that offers protection without weighing down the boat’s profile. All instrumentation is arranged on a single, easy-to-read panel, with space for the latest-generation multifunction displays.

Access to the cabin is through a forward hatch, a solution that makes the best use of space while keeping the side walkways clear. Below deck, the Coupé S13 surprises with its livability: two single berths, light oak furniture with upholstered tops, Seadeck wall and floor coverings, and a separate bathroom with electric toilet and stainless-steel sink. It is a space designed for weekend stays on board, bright and well ventilated, where materials and details make all the difference.

The onboard systems are complete and well crafted: freshwater system with a 210-liter tank, 650-liter fuel tank, pressure pump, electric bilge pump, USB and 220V sockets, and a 42-liter refrigerator integrated under the helm seat. All features that reveal a mature build approach, focused not only on performance but also on onboard comfort and overall quality of life.

At the stern, the living area extends all the way to the integrated swim platforms, featuring a double telescopic ladder for boarding and a freshwater shower. The result is a continuous, well-organized space where comfort and functionality coexist without compromise. It is a maxi RIB that offers the feel of a higher-category boat, while maintaining the practicality and versatility typical of an inflatable.
