The Infiniti 46 R is the latest model in Infiniti Yachts’ range of DSS-powered yachts. The 46 is a state-of-the-art racing yacht designed and engineered for competing in coastal and offshore events with a crew of just six or seven — far fewer than typically required on a yacht of this size.
The first Infiniti 46 R has been developed for an owner whose aim is principally the ‘Classic 600 mile’ races such as the Rolex Sydney Hobart, Fastnet Race, Middle Sea Race, Newport-Bermuda plus transatlantic races.
In addition to the twin DSS foil system, the Infiniti 46 R is available with either fixed keel or a canting keel/single canard options, depending upon owner’s preferences.
Pricing: €1,350,000 - fixed keel. €1,520,000 - canting keel.

Hull/Deck Construction Details
Gurit Engineering in the UK undertook the structural engineering of the Infiniti 46 R. The boat’s structure exceeds ISAF Category 1 Safety regulations/ISO regulations and EU regulations. This ensures the Infiniti 46 R can withstand gruelling transoceanic and offshore races like the Rolex Sydney Hobart Yacht Race and Rolex Fastnet, while being able to maintain her ultra-high performance and reliability.
The Infiniti 46 is built using Gurit pre-preg carbon fibre with Gurit M-Foam cores throughout the yacht, to minimise the risk of delamination particularly in slamming areas. All secondary bonding is in carbon and uses Gurit materials, cured under vacuum at high temperature to the engineer’s specifications. The DSS foils, canard, bowsprit, rudder, wheels and steering pedestals are all cured in an autoclave. This ensures increased strength, weight and stiffness benefits for the appendages.
Racing interior finish comprises clear coated carbon bulkheads in the main area, white painted bilges, clear sealant racing finish in the end sections. The galley is built in a lightweight carbon construction and is fitted twin JetBoil burners for the preparation of freeze-dried food efficiently when racing offshore. There are two bunks and one pipecot each side. Forward of the mast bulkhead is a wet area and a lightweight head.
The deck gear for the Infiniti 46 is predominantly Harken with 32mm Big Boat transverse jib tracks and mainsheet track.
The vang and traveller system are both hydraulic from Cariboni, keeping the deck clean and the crew placed in their optimal positions. With push button controls, the trim of these functions is easy and allows the small crew to preserve its energy when sailing offshore.
The winches are all from Harken and the Grand Prix package is standard on the Infiniti 46 R. To deliver enough power and to provide redundancy the primary, secondary and mainsheet winches are all Harken 65.3STR; the pit winches are Harken 50.2STR.
The primary and mainsheet winches are driven by a Carbon Air Pedestal from Harken, with push button controls. The pedestal also drives a hydraulic rotary pump from Cariboni, which acts as the back-up system for canting the keel in case of power failure to the ram.
The bowsprit is 2m long and removable. It is built by Isotop in high modulus carbon fibre in an autoclave and is fitted with two 2:1 tack lines, led aft to the pit under deck.
The interior is accessed via a wide top sliding carbon fibre companionway hatch with carbon washboards and a protective overhang to help keep the interior dry when sailing at speed. The
foredeck is fitted with a custom composite hatch with an inflatable seal.
The twin helm stations have carbon autoclaved pedestals and wheels from Isotop as well as adjustable foot rests for the helmsman and a carbon crash bar to protect the helmsman.
Spars & Standing Rigging
- The mast is a Ultra High Modulus Carbon section, deck stepped, twin spreader from Axxon Composites.
- The composite standing rigging and twin topmast backstays are from Future Fibres with halyard locks and furling systems from Karver.
- The boom comprises a carbon box boom, set up for three reefs with a single line reefing system that is easily removed. The reef lines are all locked with constrictors to reduce compression.
- Where possible and practical, metal fittings have been replaced by lashings or dogbones.
- Headstay tension is measured via a custom load sensor from Diverse Yacht Systems.
- The rig has two masthead halyards, one main halyard, one fractional halyard and one staysail halyard - all on locks. The genoa halyard is not on a lock.
- The mast has an external mast jack; an internal mast jack is available as an option.
- The vang is hydraulic from Cariboni as is the traveller, keeping the deck clear and allowing push button control.
- The mast is controlled by twin topmast backstays via a deflector and a 3:1 purchase.
- All running rigging is Dyneema, either SK78 or SK90.
Dynamic Stability Systems (DSS)
The Infiniti 46 is fitted with twin CFD-optimised DSS foils. They are built by Isotop in France using prepreg carbon fibre, cured under pressure in an autoclave. The foils are curved and retract into cases mounted in the forward compartment.
The foils are deployed and retracted using electrically-driven hydraulics, operated from the cockpit. There is a manual back-up to the system, but with the twin foil system it is possible to move the foil when it is completely removed from the water and thus under no load.
The twin foil set up makes for easier and safer sailing; the foil is deployed on the weather side prior to a tack or gybe so the stability is already waiting on the new course. This is very useful when gybing in heavy air and significantly reduces risk in this manoeuvre while keeping speeds high.
For maintenance purposes, the foils can be accessed via ports in the foil cases.
The Cariboni-supplied system comes complete with a forged and machined keel fin built in 17-4PH steel. The keel is driven by a single hydraulic ram built in 17-4PH with pushrod in Inconel, capable of canting the keel to 35 degrees. There is a linear sensor to monitor keel position and the system is powered by a 3KW 24V powerpack with piston pump and soft start hydraulic manifold. There is also a recovery system and a manual back-up drive for the hydraulic pump, operated by a two speed rotary pump driven by the pedestal.
The canard is built in autoclaved carbon pre-preg by Isotop. It is raised and lowered by lightweight rope-drive systems. Unlike a twin daggerboard set-up, this is lighter and, for ease of use, does not require raising and lowering through every tack. As with all appendages for the Infiniti 46 R, it is CFD-optimised.
The CNC milled bulb is made in 1.5% antimony lead and coated with two part epoxy barrier. The keel bulb is fitted with an impeller from Pixel Sur Mer to provide accurate boat speed data compared to hull-mounted systems which can struggle through aeration.
Rudder & Steering System:
Engineered by Gurit and built by Isotop in an autoclave, the rudder comprises a lifting blade, designed so it can be replaced at sea, providing an effective emergency rudder solution. Steering pedestals are made by Isotop in carbon composite an autoclave with JP3 components. Wheels are build in carbon by Isotop, fitted with a central clip-on point for a harness. The steering system can be accessed from on deck making for a lightweight, reliable and easy to maintain system.
Spares & Safety Gear
The Infiniti 46, as with all Infiniti Yachts is fitted with watertight bulkheads fore and aft with access hatches. Additionally the Infiniti 46 has a custom rudder housing which is designed to prevent any ingress of water into the yacht in the event of a rudder failure, adding a further level of security.
This system also ensures that it is a practical and realistic option to carry a spare rudder blade that can be installed, should the rudder break for any reason. Too many yachts get into severe difficulties in the event of rudder failure. Furthermore this presents a simple solution for emergency steering in the event of a steering failure; however, the steering system for the Infiniti 46 is accessed from on deck and is therefore simpler to maintain and inspect than conventional systems below deck.
The twin DSS foil system is angled in such a way that almost no water remains in the case either when the yacht is at rest or underway. Inspection and servicing is thus straightforward. Should the DSS foil fail for any reason then the yacht remains completely seaworthy and sails on as a normal sailing yacht with a keel.
