Testing Three Interactor RIBs in the North Sea

I had the opportunity to test three Interactor models: the 420, 640 and 680, all configured for professional use.

It was a beautiful day in Nieuwpoort-Bad, Belgium, with waves reaching around one metre. An ideal combination for testing these RIBs.

During the two-kilometre passage through the harbour channel, Tim and Silke introduced me to the specifications and history of the brand (see below). Both are partners in the company behind Interactor.

Once Offshore, We Could Really Open the Throttles

Although all three RIBs performed extremely well, the 680 was my clear favourite.

Its proven hull sliced confidently through the waves. Even in sharp turns, there was no cavitation.

The boat responded immediately and precisely to every change of direction. It felt like riding a train on rails.

The smaller 640 was equally convincing. Its well-established Tornado hull earned plenty of praise in the past, and it certainly didn’t disappoint this time either.

The little 420 was tremendous fun to drive.

By then, we had already covered quite some distance at sea. Time flies when you’re having fun!

With the sea conditions in mind, we took a controlled approach on the return journey.

A RIB of this size demands careful handling in waves like these. Yet I could easily imagine the 420 being deployed during floods and evacuations. It’s remarkably manoeuvrable, practical and quick to deploy.

Tubes

Another interesting detail is the tube material. No Hypalon. No PVC.

Interactor exclusively uses welded polyurethane (PU), offering exceptional abrasion resistance, colour retention and durability.

Only a handful of manufacturers worldwide produce PU tubes, and Interactor is one of them.

The trials also attracted international interest, and this wasn’t the first time.

Following the Sea Trials

Afterwards, we spent time discussing the boats.

I find these conversations just as valuable and interesting as the sea trials themselves. Questions were raised, observations exchanged and technical details discussed.

Tim and Silke answered every question, providing clear explanations that left the interested visitors thoroughly satisfied.

Worth Mentioning

Multraship has relied on Interactor RIBs for many years now, and since 2024, Interactor has been the official contracted supplier to the Belgian coastal rescue services.

All specifications of the three tested RIBs can be found below.

And one final thought: I can’t wait to test Interactor’s larger models. As we speak, the range extends all the way to 12.3 metres.


About the Brand

Interactor Boats is the new European name for boats previously sold as Tornado.

They’re still built in the same Chinese factory, by the same experienced team, with the same materials.

After Tornado Denmark tried to bring production to Denmark, the brand faced quality issues and delays.
The company entered bankruptcy proceedings in 2025. Interactor brings the well-known quality again on the European market sourced from the original factory with finishing facilities based in Belgium under the new name Interactor.


Proud to share that Interactor is a Friend of RIBs ONLY.

Aquaspirit S450: Military DNA in a Leisure RIB

Aquaspirit S450: The Compact RIB That Surprises

The Aquaspirit S450 is a compact aluminum RIB that combines rugged construction with surprising space and comfort.

Measuring 4.42 metres long and 2.14 metres wide, it accommodates six people. Its double-walled, hand-welded aluminum hull uses 4 mm marine-grade material, reflecting Aqua Spirit’s experience building RIBs for Ukraine’s armed forces.

Despite its solid construction, the S450 weighs just 212 kg. Its V-shaped hull and raised bow deliver agile handling, even in rough conditions.

A spacious cockpit, comfortable seating, and practical bow step make life on board easy. Maximum engine power is 75 hp, although a 60 hp outboard can reach approximately 40 knots.

Options include Hypalon tubes, a ski tow bar, sun deck, bimini top, and sound system.

Ranieri Cayman 41.0 Reaches 44 Knots With 700 hp

This Ranieri Cayman Offers Space, Speed and Long-Range Comfort

The Ranieri Cayman 41.0 Hard Top shows how far a modern maxi RIB can go in combining performance, comfort and genuine cruising ability.

At almost 12 metres long and 3.80 metres wide, it offers generous deck space, excellent stability and surprisingly spacious accommodation below deck.

Ranieri International uses its patented Cockpit Shock Absorber system to reduce impacts and vibrations, while the large hard top provides welcome protection around the helm and cockpit.

Aft, the dining area converts into a large sunbed, while the galley includes an induction hob, sink and 75-litre refrigerator.

Below deck are two sleeping areas, plenty of storage and a separate bathroom.

Power comes from twin Suzuki DF350 outboards, delivering 700 hp through contra-rotating dual propellers.

The stepped hull accelerates strongly, cruises efficiently at around 30 knots and reaches approximately 44 knots.

The result is a fast, refined RIB designed for much more than day trips.

Ranieri Cayman 41.0 Hard Top Test by NonsolomareTV

A Second Test by NonsolomareTV

In a previous review this Rigid Inflatable Boat (RIB) was tested by The Sea Team. Now you can compare it with this one by NonsolomareTV.

This video shows the test of the Ranieri International Cayman 41.0 Hard Top with twin Suzuki DF350 outboards, delivering a combined 700 hp.

The integrated hardtop includes a substantial windscreen, while the helm provides seating for three and a clearly organised instrument layout.

Below deck, the boat offers a forward double berth, two additional sleeping positions, storage space and a separate shower compartment.

During testing, the Cayman reached planing speed progressively, without excessive bow rise, and settled quickly into comfortable cruising speeds.

Around 30 knots, reported fuel consumption was approximately 3 litres per nautical mile, increasing at higher cruising speeds.

Maximum speed reached about 44.5 knots, while high-speed turns showed predictable steering response, limited heel and no reported propeller cavitation.

Ranieri Cayman 41 Test Data Comparison

Two independent tests of the same Ranieri Cayman 41.0 Hard Top show similar performance, but notable fuel-consumption differences. Variations may result from fuel and water load, passengers, sea state, weather, trim, and other test conditions.

Remark; At 20 knots, Test 2 indicates 3.81–3.89 l/nm. As this figure is interpolated near the transition to planing, the 91–94% difference should be considered indicative rather than definitive.

Ranieri Cayman 41 Hard Top Test & Twin Suzuki 350

The Ranieri Cayman 41 Sea Trial

The Ranieri International Cayman 41 Top was tested with twin Suzuki DF350 MD outboards, producing 700 hp.

In the video you can se that the conditions were calm, with a developing long swell and light breeze providing stability testing.

With two people aboard, fuel stood at 20 percent and water at 50 percent.

The stepped hull reached planing speed with limited bow rise and remained composed as speed increased. At 4,250 rpm, the boat recorded 32 knots while consuming 124 litres per hour.

Maximum speed reached 44 knots at 6,000 rpm, with combined fuel consumption of 220 litres per hour. The hull stayed dry during turns, wake crossings and higher-speed manoeuvres.

Steer-by-wire controls and counter-rotating propellers contributed to handling, comfort and reduced vibration throughout the test.
