Andare Oltre is a brand new HeySea sailing catamaran, delivered in 2026, and she brings the width and volume of a much larger yacht into an 18 metre package. Ten guests travel in five cabins across a wide, level platform, with an open plan main deck, a flybridge lounge under a folding sunroof, and the quiet, steady sailing that only twin hulls provide.
Under sail is where she comes into her own. Two hulls carry a beam of over eight metres, so she stays level across the wind where a monohull would heel, and the engines stay off for hours at a time. The rig is set up to be worked by a small crew, which keeps the sailing part of the day simple rather than a project, and the shallow draft of a catamaran reaches the bays the deeper boats have to watch from outside.
The main deck is one bright room. A light salon in pale timber and white runs across the full beam, a dinette and soft seating gathered under glass on three sides, and the galley flows along one side so the cook stays in the same room as the group rather than shut away in a pantry. A full galley island anchors the forward end, its work surface and storage facing the salon and the deck beyond the glass. Keeping the cooking, the dining and the lounging in one open space is what makes an 18 metre boat feel far larger than her length.
Outside, the flybridge lounge sits under a folding sunroof with its own dining and loungers, an upper room that opens to the sky or draws shade across as the day turns. Forward of the house the deck opens into a sunken lounge with soft seating and a low table, clear of the main circulation and the quietest spot at anchor. Aft, the main cockpit is a shaded dining space that steps down toward the swim platform and the water.
Below, the accommodation is unusually generous for the length. Five cabins carry ten guests, which is real volume at 18 metres and the reason she suits a family or a group travelling together. The master takes a wide bed under a skylight with good natural light down the hull side and its own bathroom. A VIP carries a double bed and its own skylight, and a double guest cabin with a marble headboard wall follows, each finished to the same standard and each with a bathroom close by.
Her watersports kit is set up for an active week off the swim platform: an e-foil, a Seabob, a wakeboard, water skis for adults and children, and a Highfield tender to run the beach trips. Three crew keep the day moving for a full party of ten.
Andare Oltre charters the Greek islands under sail, and the platform fits the ground well. The wide, stable decks make the long lunches and the quiet anchorages the point of the trip, the shallow draft opens up bays the deeper boats avoid, and the volume below means a large group is not living on top of one another. A monohull of the same length would carry three cabins and a corridor; she carries five and a main deck you can lose people on. That difference is the whole case for a catamaran at this size, and it is felt most on the boats that charter a full party rather than a couple. Delivered new in 2026 and chartering from 25,000 euros a week, she is one of the newest and most spacious sailing catamarans at her length working the islands this season.
