Performance, liveability, and comfort in a new dimension. That is how the new Cayman 37.0 Hard Top, recently launched by Ranieri International as it celebrated its 60th anniversary, can be summarized. The Calabrian shipyard, founded in Soverato and today an established player in international markets, chose its home waters to celebrate this major milestone and introduce the next phase of its evolution. In this setting, we had the opportunity to step aboard the new Cayman 37.0 Hard Top, a maxi-rib positioned between the Cayman 35.0 and the Cayman 38.0. Its overall length of 11.30 meters and beam of 3.80 meters already say a lot about its ambitions, but its defining feature is that, thanks to a hull length under 10 meters, the 37.0 remains certified as a watercraft.
The project aims to combine generous dimensions and great liveability with the ease of use typical of this category. The rigid hardtop protects the central area, the cockpit offers generous space, and the outboard propulsion on the model tested by The International Yachting Media reaches a pair of 350-hp Honda V8 engines. Below deck, there is sleeping accommodation for four people across two distinct areas, complete with a separate head, while the capacity reaches up to 24 people. It is a recipe Ranieri knows well: turning a large inflatable boat into a true platform for living on the sea, without compromising on performance.
Sea trial of the Cayman 37.0 Hard Top
We are at Ranieri International’s private marina in Soverato, and the sea before us is that deep, calm, crystal-clear blue that seems tailored to invite you to cast off. After raising a toast to the shipyard’s anniversary, the moment we look forward to most arrives: firing up the engines and discovering what this boat can truly do.
The Cayman 37.0 Hard Top is slightly smaller than the Cayman 41.0 Hard Top we previously tested, but the initial sensation upon leaving the marina is that of being aboard a vessel that is just as solid and stable. The difference in size is felt mostly in terms of space, but not in the overall sense of safety the boat conveys.
The interior, cabins, and below-deck layout mirror the philosophy of its larger sibling. The main difference lies in the cockpit, while everything else has been scaled down with meticulous attention to preserve an open feel that is by no means guaranteed on a vessel in this class. Right here comes one of the first surprises: the enormous bow chaise longue. It is likely the most sought-after spot for guests, where one naturally settles as soon as the boat clears the port. The space is truly generous, allowing you to enjoy the navigation without feeling cramped.
Then the throttles are pushed forward, speed builds naturally, and the Cayman 37.0 Hard Top begins to reveal its character. The boat glides smoothly over the water, accelerating effortlessly. Compared to the 41.0, the slightly shorter hull means you feel a bit more movement when crossing waves, yet stability remains one of the project’s standout traits. The hull cuts through the water decisively, and even when we start playing with our course—initiating turns and deliberately crossing our own wake—the Cayman maintains composed and predictable behavior. It is an essential feeling, especially on a vessel designed to carry a large crew. You never feel as though you are pushing the boat beyond its limits. Even when picking up the pace, coming onto plane at 3,500 rpm and 24 knots, the response remains progressive and reassuring.
A significant contribution comes from the overall ergonomics of the vessel. Numerous handrails, well distributed along the hull, allow for safe movement and add a sense of reliability that matters even more than a few extra knots on a maxi-rib built for cruising.
46 knots with two 350-hp Honda V8s
The helm station is comfortable and logical. Once seated at the wheel, everything is within reach, and control responses are practically instantaneous. The Cayman 37.0 HT follows inputs without hesitation, allowing the driver to focus on navigation and course lines.
During our test, the boat was equipped with twin 350-hp Honda V8 outboards, bringing the total output to 700 horsepower. With a half tank of fuel and six people aboard, we reached 46 knots—a remarkable speed, especially for a vessel designed not only for pure performance, but also for spending extended time at sea.
The interesting detail, however, is not just the top speed, but how the Cayman reaches it: with moderate fuel consumption relative to speed (under 15 liters per hour at 9 knots, and 48 liters per hour when coming onto plane at 3,500 rpm and 24 knots) while offering a constant feeling of control at the helm, even when picking up the pace.
The hardtop: uncompromising comfort
The hardtop has become an almost essential feature on large cabin RIBs, but here it plays an even more vital role. Under the hot Mediterranean sun, having a rigid shelter overhead completely changes the quality of the ride. Ranieri has done exceptional structural work here: during our test, even at high speeds, we noticed no creaking or structural flex. The hardtop remains quiet and solid, contributing to the overall impression of sturdiness throughout the trip.
The setup for the rear sunshade is also very practical. Dedicated carbon poles extend shade over the entire stern area, turning the cockpit into a true living space while anchored. At the center is an electro-hydraulically operated table that can be used at standard height for dining or lowered partially to support cushions, creating an additional chaise longue. It is a simple yet effective solution that enhances cockpit modularity to suit different needs.
The Cayman 37.0 Hard Top proves to be an enjoyable boat to drive and a vessel designed for living aboard. It can accommodate a fun day on the water with friends, yet it has everything required to spend the night out and turn a weekend into a short cruise.
Inside the Cayman 37.0 Hard Top
Compared to the previous model, the new Cayman 37.0 HT features lighter-toned cabinetry. This choice pays off by boosting perceived brightness and making the spaces feel even more open.
The interior stands out for its generous volume and a spatial layout uncommon on a vessel of this size. The main cabin receives abundant natural light through large tempered glass windows and flush-mounted portlights integrated into the structure.
The layout provides four berths split into two distinct areas—a solution that enhances privacy on board, making the Cayman suitable for both day trips and multi-day cruises. This is complemented by ample storage cabinetry. Storage options have been maximized so you can bring everything needed for a cruise without cluttering the living quarters.
The head is enclosed and features its own window. Here, too, the dimensions exceed expectations for a boat of this exterior profile, while the finishes and linear LED lighting create a refined, bright space.
A structure designed for comfort
Behind the performance of the Cayman 37.0 HT is more than just an efficient hull. The design incorporates structural solutions engineered to increase rigidity, comfort, and noise reduction. The Fully Developed Cockpit System technology utilizes a single-piece deck structure designed to eliminate joints and exposed seams, delivering greater structural integrity while reducing noise and vibration transmission.
Complementing this is the patented CSA – Cockpit Shock Absorber system, where the assembly between hull and deck acts as a structural suspension system. The system is designed to absorb and dampen impacts from waves, improving comfort and extending structural longevity.
Finally, the new stepped hull (redan) was developed to boost hydrodynamic efficiency, balancing performance, fuel economy, stability, and safety—even when sea conditions rough up. During our test, these solutions proved their worth through a pervasive sense of solidity. The Cayman 37.0 Hard Top never feels like a boat overwhelmed by the sea; it cuts through it, maintains composure, and holds its ground.
A deck designed for outdoor living
The deck is arguably the centerpiece of the design. Ranieri focused on making every area usable and easily reconfigurable without compromising traffic flow. Forward, the chaise longue dominates with clean, ergonomic lines; amidships, the fiberglass hardtop with a tempered glass windshield protects the helm and living space from the elements. Linear LEDs integrated into the structure illuminate the space at night, transforming the maxi-rib’s vibe after sunset.
The main deck lounge is exceptionally well-equipped. The galley unit includes a stainless-steel sink, an induction cooktop, and a 75-liter stainless-steel drawer refrigerator. This setup makes hosting lunches and evening drinks effortless without needing to go below deck. The rear-facing fold-down seat is another clever feature: it adds seating when needed or folds completely flat to maximize deck space.
At the stern, the U-shaped dinette features a table equipped with an electro-hydraulic system that retracts flush into the floor. With the push of a button, the table lowers so the entire area converts into a large, flat sunbed. The cockpit seamlessly transitions throughout the day from a dining area to a conversation lounge, open deck space, or expansive sunbathing platform. Finally, retractable ladders are integrated into the stern bracket, keeping lines clean when stowed while ensuring safe, easy water access.
The helm station of the Cayman 37.0 Hard Top
The helm console follows the same philosophy as the rest of the boat: clean lines, logical layout, and maximum functionality. The helm seat is built for long runs, offering strong postural support. Visibility is broad, allowing clear views of both your course and immediate surroundings. This detail is crucial on a vessel that, with a capacity of up to 24 passengers, may frequently carry large groups. The console layout and controls keep situational awareness high, allowing quick reactions to course corrections.
Design and customization
The Cayman 37.0 HT is also highly customizable. The shipyard offers three fiberglass gelcoat colors—white, gray, and black—along with 20 upholstery shades and multiple synthetic teak options. These choices allow for vastly different takes on the same foundation, ranging from an aggressive, sporty look to an elegant, understated layout. This flexibility broadens the model’s appeal: the Cayman 37.0 HT can adapt to distinct owner personalities without ever losing its core identity. It is a versatile boat, not just in spatial layout, but in aesthetic options and overall lifestyle appeal.
Conclusion
With the release of the Cayman 37.0 Hard Top, Ranieri International reinforces a key pillar of its legacy: translating over six decades of expertise into continuous innovation. The launch of this model is not a finish line, but a launchpad toward an expanding lineup of larger models designed for owners seeking comfort and performance.
The Cayman 37.0 HT hits a sweet spot. It doesn’t force a choice between speed and comfort, or day trips and overnight cruising. It is fast and responsive when you push the throttles, yet provides four berths, a separate head, a galley, expansive exterior space, and everything needed for multi-day trips.
Our trial showcased a well-balanced vessel. The hull is stable, control response is instant, the build feels solid, and the space is smartly used. The Cayman 37.0 HT bridges two seemingly opposite worlds: a sporty edge evident in its 46-knot top speed, and a cruising nature that shines the moment you stop watching the tachometer and start enjoying the water. That is perhaps its most compelling trait. The new Cayman 37.0 HT is built for owners who want to travel far without giving up the thrill of a fast day on the water, seeking uncompromised space and build quality. It marks a natural next step for Ranieri International, which after 60 years continues to build its future on a simple truth: a boat must first and foremost be great to live on at sea.
