McConaghy Boats Custom 2026 "INFINITI 105"

​BUILD

The INFINITI 105 delivers a step-change in performance and comfort to the sailing superyacht world, with greater performance and comfort than any comparable yacht and reduced heeling and pitching. The Dynamic Stability Systems (DSS) foil has already proved to reduce heeling by as much as 30% and pitching (the principal reason for seasickness) by over 40%. This ensures that the INFINITI 105 is easy to sail, significantly faster and extremely comfortable when under sail. For the owner, this means extended cruising and happy guests who can enjoy the amenities and luxury aboard.
 

Infiniti Yachts, renowned for its cutting-edge design and groundbreaking technology, has teamed up with McConaghy Boats, a global leader in high-performance composite yacht construction, to bring forth the Infiniti 105. This collaboration represents the pinnacle of expertise, marrying Infiniti's visionary design philosophy with McConaghy's unparalleled craftsmanship.

The interior is built to the highest standard using lightweight composite panels, surfaces in wood or covered in leather or fabric.
 

The INFINITI 105 is built in a female mould using advanced composite sandwich construction with Carbon Prepreg laminates cured under vacuum at high temperature.
 

The INFINITI 105 uses the patented Dynamic Stability System (DSS), consisting of a single, sliding foil that can be extended out, one side at a time. Operation of the foil is by three buttons on each helm pedestal: starboard, port and center. There are displays showing the position of the foil.
Under sail, the DSS increases righting moment and thus performance, resulting in a comfortable, optimum heel angle of 12-15 degrees while reaching and less than 20 degrees when sailing upwind.
 

The INFINITI 105 comes with the option of a hydraulically lifting keel for improved performance and ability to access shallower ports. Draft is 3.60m Up and 5.60m Down, although this could be increased for a more performance-orientated evolution.
 

The INFINITI 105 has a Sub-anchor, customized Poole type of 125kg with 12mm chain.
 

EXTERIOR

The INFINITI 105 is one of the most breathtakingly sleek and beautiful yachts ever conceived. 

In order to appeal to both traditional and more modern tastes, INFINITI give two options which involve a small change in tooling during build.

The first option is for a more traditional Plumb Bow.

The second option is for the more modern and aggressive styling of a Reverse or Dreadnought Bow. Take your pick.

DECKS 

The INFINITI 105 comes as standard with a high-quality teak deck however there is an option for Cork decking as both lightweight and more eco-friendly option.

Aft Deck:The large, open, aft cockpit lends itself well to sunbathing while at anchor or gently underway. The transom door opens to give a nice beach club area with steps up to the aft deck.

Foredeck: The foredeck is large, flush, and uncluttered.

INTERIOR

MAIN SALOON / DINING AREA: The sleek glass superstructure echoes the curves of the Infiniti Design. The main salon seating is positioned beneath this, allowing for a dramatic influx of natural light to the interior. This arrangement also eradicates the traditional corridor that leads through a salon and creates a more dynamic and social space. The INFINITY 105 can accommodate six guests in three stunning cabins.

COCKPIT:

Several options for layouts have been suggested, but the owner can drive the final design and details to suit their wishes. One arrangement is more suited to cruising, and the other offers more open space for ease of crew movement when competing.

The entire guest cockpit and all the way forward to the mast can be shaded by an easily deployed awning from either side of the boom.

There is also a sprayhood dodger that deploys from a moulded recess in the coach roof with a hinged, rigid cover.

The aft working area of the cockpit is cleverly laid out to allow easy control of the generous sail plan with minimum crew and effort. Most sail controls are push-button hydraulic or electric. Mainsheet and self-tacking jib sheet are both on captive winches. Primary, secondary, and Runner winches are Harken 1235.

Two beautifully designed composite, lightweight wheels drive the Infiniti 105s transverse twin rudders.

GALLEY:

Design/style notes: There are two options for gally layout: ´A´ Aft and ´B´ Forward.

Option ´A´ is situated starboard aft-facing outboard. This subsequently allows an impressively grand and open saloon.

Option ´B´, with a galley situated ahead of the saloon, is also an attractive solution.

Both options have a choice of Corian or Stainless-steel countertops and all have galley cabinets finished in oak. There is dedicated storage for glassware, cutlery, crockery, pots and pans. Frigonautica Fridge and Freezers. Miele induction hob and gimballing oven. Miele dishwasher and microwave.
