Design & Construction

Designed around a displacement w/ bulbous bow steel hull and an aluminium superstructure she features a 29' beam and a 9'2" draft. The yacht is built over 3 decks with an internal volume of 491 GT (Gross Tonnes).

This was the first yacht built on the EP150 design. Launched in January 2012 this yacht undertook sea trials over the following months. She was delivered to her owners in April 2012.

Exterior Design

The 45m (147.6ft) Sun One was built as Horizon’s entry into the serious expedition yacht market, but the exterior avoids the heavy industrial styling often associated with long-range explorers. Designed by JC Espinosa, the profile keeps the sleek Horizon family look with stretched glazing, clean horizontal lines and a sharp near-plumb bow that gives the yacht a more contemporary stance underway.

The steel hull and aluminium superstructure were developed to Bureau Veritas Ice Class 1D standards, so beneath the smooth styling is a platform intended for colder regions and extended passagemaking. The hull carries substantial volume at 491GT, but careful window placement and stepped deck levels stop the yacht from appearing bulky. Large dark window bands visually lengthen the profile while the upper decks taper gently aft into broad entertaining terraces.

The bow sections have a purposeful look with deeply recessed anchor pockets and heavy stainless detailing integrated cleanly into the hull sides. The freeboard is high, but the long sheer line and dark glazing reduce the visual height. Wide side decks and substantial bulwarks reinforce the expedition brief without making the yacht feel commercial.

Outdoor living takes priority across all three upper decks. The aft main deck forms a sheltered dining terrace with space for a large table beneath deep overhangs from the bridge deck above. One of the overhead televisions drops down from the ceiling structure, turning the space into an outdoor cinema or sports-viewing area.

Above, the bridge deck aft works as a second social terrace with loose lounge seating arranged around low tables. Immediately forward sits the raised circular spa pool, one of the yacht’s defining visual features from above. The jacuzzi is surrounded by built-in sunpads and protected by the overhang from the sundeck structure above.

The sundeck itself is unusually large for a yacht in this category. Beneath the hardtop is a full sit-up bar with seating for eight guests and a dedicated outdoor galley opposite. Forward and aft sections remain flexible for loose furniture, loungers and open-air dining setups. The scale of the deck gives it more of a rooftop terrace feel than a typical flybridge arrangement.

Forward of the wheelhouse, the Portuguese bridge incorporates guest seating with elevated views across the bow. Beneath the deck sections here are concealed storage areas for PWCs and the crew tender, helping keep guest decks free from cranes or exposed toys.

Aft, the swim platform and tender handling areas were designed around long-term cruising practicality. The tender garage incorporates a slipway launch system capable of handling a tender slightly over 5.5m (18ft), positioned between machinery spaces at the stern. Despite the yacht’s expedition capability and substantial engineering spaces, the exterior remains notably clean and uncluttered throughout.

Interior Design

The interiors by Schnasse Interior Design lean toward a cooler Northern European style rather than traditional high-gloss superyacht décor. Satin-finished oak appears throughout the yacht alongside white leather seating, pale overhead panels and textured fabric wall sections that soften the scale of the large interior spaces.

The main salon has a calm, understated atmosphere built around horizontal lines and natural materials. Oak wall panelling uses subtle horizontal banding to visually stretch the room while planked oak flooring reinforces the long proportions. White Majilite ceiling panels and recessed lighting keep the space bright without relying heavily on mirrored finishes or decorative detailing.

A fibre optic ceiling feature above the main seating area introduces a softer evening mood while large windows bring in consistent natural light during the day. Seating arrangements remain practical and social rather than formal, with oversized sofas positioned around low tables and entertainment systems.

The formal dining area sits forward of the salon behind a separating wall that creates a quieter, more enclosed setting. Low cabinetry wraps around the perimeter while the space can function as either a dining room or a private meeting area depending on use.

One of the most distinctive design details throughout the yacht is the flush oak trim running along the upper sections of walls and partitions. Rather than traditional crown mouldings, Schnasse used broad oak edging to create a cleaner and more contemporary transition between surfaces.

The upper salon shifts toward a more relaxed social atmosphere with a sit-up bar, lounge seating and fold-down television. Large Bose surround-sound systems and integrated entertainment features suggest this deck was designed as the yacht’s primary evening gathering space.

The wellness areas continue the same restrained styling approach. Frosted glass panels with reed-pattern detailing divide the gym, sauna, steam room and spa areas without fully separating them from the upper deck lounge spaces.

The galley prioritises practicality for long-range cruising. While conventional in layout, the cold storage capacity is unusually substantial thanks to the adjoining walk-in refrigerator positioned directly beside the cooking area. This arrangement supports extended cruising schedules without constant reprovisioning.

Crew areas were also given significant attention. The crew mess is bright and functional with painted finishes, laminate surfaces and additional oak detailing that visually links it with the guest spaces. Storage and circulation areas appear unusually generous for a yacht carrying nine crew.

Accommodation

Sun One accommodates up to 10 guests across five cabins with space for nine crew.

The owner’s suite occupies the forward section of the main deck and functions almost like a private apartment within the yacht. Access comes through a transitional office space that separates the suite from the main guest circulation areas. The cabin itself spans the full beam of the superstructure and incorporates extensive built-in storage, large wardrobe spaces and a substantial en suite finished in stone and mosaic tile.

Fabric wall panels and soft furnishings help reduce the scale of the suite while maintaining the quieter Northern European tone found throughout the yacht’s interior.

Guest accommodation sits amidships on the lower deck where the yacht’s beam provides generous cabin widths. The layout consists of two double cabins and two twin cabins, all with private en suite bathrooms. Positioning the guest cabins near the centre of the hull helps reduce movement underway during longer passages.

The crew accommodation is positioned forward on the lower deck and connects efficiently with operational areas through separate circulation routes. A hidden watertight door links the guest corridor directly to the crew spaces when needed. The crew mess itself is unusually spacious with strong natural light and practical storage throughout.

The captain’s cabin and radio room sit aft of the wheelhouse on the bridge deck, allowing direct operational access without crossing guest areas.
