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.

Ranieri International Cayman 37.0 Hard Top Test

Ranieri Cayman 37.0 With Twin Honda 350 V8 Outboards

The Ranieri Cayman 37.0 was tested off Soverato with twin Honda 350 hp V8 outboards, delivering 700 hp combined.

Conditions were calm, with three people aboard, 30% fuel and an empty freshwater tank.

The double-stepped hull moved onto plane progressively, while bow rise remained limited and visibility from the helm remained clear.

At 28 knots, combined fuel consumption reached 54 litres per hour, representing an efficient cruising point during the test.

Speed increased to 38,2 knots at 5.000 rpm, with consumption rising to 97,4 litres per hour.

Further trimming lifted speed beyond 42 knots without additional throttle input.

Maximum recorded speeds of this Cayman 37.0 approached 46 – 47 knots!

During turns and wake crossings, the hull remained controlled, with limited roll and noticeable impact absorption throughout.
