2017 ROYAL HUISMAN Custom Dubois 58m

BROKERS COMMENTS:

 

This is a unique and exciting opportunity to acquire the late Ed Dubois last design and commission. Built by Royal Huisman and launched in 2017, Ngoni truly is one of the the worlds most striking and innovative yachts ever built. Her purposeful plumb bow, distinctive reverse sheer lines, full glass deckhouse, cascading tiered beach deck aft and 71m (232ft) carbon mast wont fail to impress. With the lifting keel down (8.1m) this yacht is fast - all aided by the yachts low profile and sleek uncluttered deck. 

This is one of the worlds largest sloops with serious 'Wow' factor. Ngoni's guest accommodation is beautifully styled by Rick Baker Ltd.  In 2024, NGONI underwent a significant refit, expanding the accommodation on-board: the gym was replaced with a luxurious twin berth cabin and ensuite bathroom; and a single berth sofa bed has been added to the owner's office.
