Riva Aquarama – RC Model

Premier Ship Models have recently completed a custom project for a beautiful remote-controlled Riva Aquarama model, measuring precisely 1 metre in length! It is complete with lights and the sound of a V8 engine, two propellers, dials on the dashboard (that also light up), brushless electric motors, a US flag, simulated blue and white leather for added realism, a removable deck to access the motor, a wood finish, and a battery life of 30 solid minutes!

The Riva Aquarama is a high-end wooden runabout crafted by the Italian boatbuilder Riva. It remained in production, along with its offshoots – the Lungo, Super and Special – from 1962 to 1996. Its hull design evolved from the earlier Riva Tritone, itself influenced by the classic American mahogany Chris-Craft runabouts. Celebrated for its performance, elegance and exquisite workmanship, the Aquarama came to be regarded as the boating world’s equivalent of a Ferrari. Riva, established by Pietro Riva in 1842, was overseen by Carlo Riva until he sold the company to the American Whittaker Corporation in 1969.

The Aquarama is widely considered Carlo Riva’s most iconic creation, and over the years it has acquired an almost mythical status among enthusiasts. Its evocative name – partly inspired by the Cinerama widescreen cinema format popular in the early 1960s – is reflected in the boat’s sweeping, wraparound windscreen, which recalls a more glamorous era.

Measuring between 8.02 and 8.78 metres, the Aquarama’s hull was clad in varnished mahogany that showcased the timber’s natural grain. Every model was fitted with twin engines, achieving top speeds of around 45 to 50 knots depending on specification. Engine outputs ranged from 185 to 400 horsepower per unit, supplied by Riva-tuned versions of Cadillac and Chrysler engines among others. A cushioned sunpad sat above the engine bay, and the boats were equipped with a folding hood that stowed neatly behind the cockpit and rear seating. Many examples also featured a bathing ladder mounted on the stern.

This particular model was made for a private client; therefore, we cannot delve into detail. However, we can proudly say that they were left absolutely thrilled with the end result, and were thoroughly impressed by the level of professionalism and efficiency we displayed throughout.

The model was initially produced using advanced 3D-printing methods and then carefully hand-finished to achieve a refined, high-quality appearance.

Its construction relied exclusively on ABS resin, timber and fibreglass, with selected areas accented by chrome detailing to elevate its overall elegance.

3D printing is a highly specialised discipline that requires thorough knowledge of three essential considerations:

• The characteristics and behaviour of the chosen materials
• The strengths and limitations of the printing equipment
• The design goals and the desired final look

Such work demands significant skill. Our 3D-printing expert oversees two vital stages: first, the development and preparation of the digital model for production; and secondly, the meticulous smoothing and finishing of each printed part to ensure a polished, professional result.

To enable remote-control functionality, the model was engineered with an internal structure capable of housing miniature servos, a compact motor, and an electronic speed controller. Channels were incorporated during the design phase to accommodate wiring, while the hull was reinforced to support the vibration and torque of powered operation. A waterproof compartment was added to protect the receiver and battery pack, allowing the finished model to be operated reliably and safely on the water.

The custom-built Riva Aquarama model was produced largely through 3D-printing processes, combined with fibreglass and acrylic elements, and completed with chrome accents — a clear demonstration of technical expertise, creativity and meticulous precision.

Before any physical work began, every aspect of the commission was carefully discussed and agreed with the client. This included exact dimensions, design details, stylistic preferences, payment terms and the expected project schedule. Establishing this framework at the outset ensured a streamlined workflow and minimised the potential for any misunderstandings during the build.

Work commenced with the fabrication of the hull, which serves as the structural core of the model. This phase demanded rigorous measurement and skilled craftsmanship to reproduce the proportions of the full-sized vessel with accuracy. Once the hull was in place, the focus shifted to the upper components, such as the decking, windscreen and flag poles.

The painting phase required exceptional care to achieve a smooth, premium finish. The hull received a crisp white coating, while the main body showcased an elegant wood-effect surface. In the final detailing stage, the entire model was gently cleaned and polished to a mirror-like sheen, with the removable deck receiving its own finishing touches.

The assembly of the battery pack proved particularly intricate, and all wiring was routed cleanly and professionally, kept as unobtrusive as possible and visible only when the deck is lifted away. To complete the build, a US flag was fixed to the stern, and the electronics underwent a full check to confirm that everything was functioning correctly.

We are immensely proud of this Riva Aquarama RC model, and it’s always such fun to work on remote controlled models!

The client was really happy with the finished product, and now we turn our attention to our other ongoing projects!
