The yacht, which will debut at the Genoa Boat Show from October 1 - 6, features exterior design by RWD and interiors penned by New York studio Bonetti/Kozerski Architecture.

Elsewhere, Rebeca has a beam of 8.5 metres, draft of 2.14 metres, vertical bow and a 385GT interior spread across four decks.
Large windows on the upper and main decks flood the interior with natural light while the interiors have been designed with “a desire for symbiosis with nature”.
Accommodation is for a total of 10 guests in five cabins and seven crew in four cabins, including the captain’s cabin on the upper deck.
Elsewhere, the yacht features wide spaces, high ceilings and extensive glazed surfaces. At the stern, two platforms fold out to extend the beach club, which centres around an infinity pool.
Power comes from two MAN V12 engines for a top speed of 18 knots and range of 4,000 nautical miles at 11 knots.
Bonetti/Kozerski Architecture co-founder Dominic Kozerski previously said the interior would encompass an “unprecedented fluidity”.
“Identical materials and colours are used for both the interiors and exteriors, giving a sense of apparent informality to what is in fact an extremely elegant and sophisticated yacht,” he added.
RWD’s Adrian Chisnell said: “On this yacht you experience the sea in an entirely new way. The wide spaces, the hydrotherapy pool and easy access to the water present guests on Oasis 40m with an onboard lifestyle that is both dynamic and relaxing.”
