APEX 850 – the world's largest sloop

This is undoubtedly the most ambitious and inspiring concept yet to be developed in an exclusive relationship between Royal Huisman and the renowned superyacht designer Malcolm McKeon.


Above her sleek and powerful 85 m / 279 ft hull, APEX features a towering 107 m / 351 ft air-draft rig that will dominate the marine landscape wherever in the world she drops anchor. Stunning minimalism in every aspect of McKeon’s radical design serves to emphasise the grace and potential of this extraordinary ocean greyhound. Even the all-glass superstructure, encompassing some 200 m2 / 2150 ft2 of guest cockpit and a luxurious saloon, scarcely seems to be there – an understated, almost ethereal presence.

APEX 850 is fully resolved in terms of design, naval architecture and engineering. Technical challenges have been identified and addressed; potential for refinement explored and incorporated. The concept is therefore an unprecedented opportunity for an ambitious and creative Owner to stamp their individuality while still viewing an unusually attractive delivery date for such a project.


Malcolm McKeon comments: “The sailing experience of APEX 850 will be sensational, with speeds in excess of wind speed in most conditions. Her retractable keel, optimised weight distribution and limited heel angle will provide stability, comfort and safety for all on board. Her twin high aspect rudders will provide a rapid response to her fly by wire helm.”

Royal Huisman CEO Jan Timmerman adds: “Two of the world’s ten largest sailing yachts, ATHENA and SEA EAGLE II, are Royal Huisman builds and APEX 850 would make a fitting third, easily becoming the largest member of this elite circle. Every Royal Huisman yacht benefits from the research, innovations and challenges of our previous builds, ensuring this would be the finest yet.”
