A sub 500 tonne world cruiser
The Oceano 46 sits in the middle of the displacement range, above the 39 and 44 and below the 50, 52 and 60. At 45.5 metres she is deliberately kept under 500 GT, a threshold that keeps crewing and regulation simpler for a private owner. To hit that mark on a boat this size the hull is built in composite, lighter than the steel used higher up the range. The result is a lot of yacht in a package that stays manageable.
The Oceano idea is quiet, long range comfort with the pace kept modest and the reach kept long. The 46 delivers exactly that, with a 4,000 mile range and a serene ride. She is built for owners who measure a yacht by where it can take them and how well it lives at anchor. Staying under 500 GT is a deliberate choice to keep the whole experience relaxed.
Two designers, one calm profile
The 46 is unusual in the range for splitting its design between two names. Stefano Righini drew the exterior, bringing a clean and timeless profile with a well proportioned superstructure. Alberto Mancini took the interior, giving the inside spaces a contemporary and restful feel. That pairing produces a boat that is coherent outside and in without leaning on a single signature.
The composite hull keeps weight down and helps the 46 stay efficient over long distances. Wide glazing floods the interior with daylight and connects guests to the sea. Deck spaces are generous, with a good sun deck and an aft cockpit made for long lunches at anchor. A swim platform and beach area aft bring guests close to the water when the boat is stopped. The overall look is quiet and confident, the sort of boat that ages gracefully across many seasons.

Space and stillness inside
Below, the 46 sleeps up to 12 guests in five cabins, with crew of nine in five more. A full beam owner's suite takes the widest section of the hull, and the guest cabins are laid out for privacy on long trips. Large windows keep the lower deck bright and the mood open. The main deck saloon flows aft to the cockpit for easy indoor outdoor living.
Mancini's interior leans modern and calm, with light materials and clean joinery throughout. Every 46 is a semi custom project so owners can set layout and finish to their own taste. Comfort and storage are worked to a proper world cruising standard. For a boat kept under 500 GT the sense of volume is very generous.
Quiet miles with steady stabilisers
The 46 is powered by twin MTU 12V 2000 M86 engines of 1,700 hp each, driving conventional shaft lines. Top speed sits around 16 knots with a relaxed cruise near 11 knots. At that pace the range reaches about 4,000 nautical miles, enough for long ocean legs. The whole drivetrain is tuned for quiet, efficient running over distance.
Stabilisers that work both at anchor and underway are central to the 46's comfort. At rest they damp the roll that spoils time at anchor, and on passage they keep the boat steady in a seaway. Combined with the calm displacement hull, they make long trips easy on guests. The twin shaft drivetrain is simple and robust, the sort of setup that keeps working far from a shipyard. Fuel burn stays low at the modest cruising speed, which is part of how the boat reaches 4,000 miles. This is a boat designed to be lived aboard for weeks without fatigue.
The owner it suits
The 46 suits the owner who wants a proper long range yacht that stays under 500 GT on purpose. That threshold keeps crew numbers, running costs and paperwork lighter than a bigger steel boat. The 4,000 mile range and steady stabilisers make it a true go anywhere platform for a family. Owners who value calm and comfort over speed will feel at home aboard.
It also appeals to a buyer who wants a distinctive design without a single house style stamped over everything. The Righini exterior and Mancini interior give the boat its own balance. Comfort at anchor is as strong as the ability on passage, which matters for long stays in one bay. For a manageable world cruiser with real reach, the 46 is well judged.
Who it is for: The owner who wants a distinctive long range cruiser kept under 500 GT for lighter crewing and easy paperwork.
