Entering from the teak aft deck through custom double stainless steel and glass watertight doors, you step into MAHANA’s spacious 20-foot full-beam Main Salon, where warm American Cherry joinery with Madrone Burl accents creates an inviting coastal elegance. Generous headroom and oversized frameless windows enhance the sense of openness while filling the salon with natural light and sweeping water views.

A substantial custom wrap-around sectional sofa, extends the full length of the starboard side of the salon, providing generous seating for relaxing or entertaining and was professionally recovered in designer fabrics in (2019.) Two comfortable swivelling barrel chairs complement the seating area. A custom-engineered upholstered ottoman/coffee trunk, designed and built specifically for MAHANA, anchors the seating arrangement while providing convenient built-in storage.

Oversized frameless salon windows bring in abundant natural light and offer sweeping water views. Hunter Douglas 2" blinds, framed by fabric lambrequins, provide privacy while maintaining the yacht’s elegant interior styling. Soft soffit and overhead rope lighting, together with new carpeting installed in (2019,) enhance the warm and inviting atmosphere throughout the salon.

Central to Mahana’s South Pacific theme, and prominently displayed in her Main Salon, is an original bronze sculpture titled “Harmony, by renowned artist Sandra Koop, depicting sea turtles in graceful, choreographed motion. The sculpture stands 31.5 inches tall, and with its marble base weighs approximate 101 pounds. Accented with blue-green patina, that complements the salon’s interior palette, the piece is accompanied by a certificate of Authenticity from Foundry Master Charles L. Wambold and carries a stated value of $20,000.

The salon’s entertainment system centers around a Samsung 50" curved flat-screen television on a retractable lift, paired with a Denon wireless home entertainment system that is multi-zoned to serve both the Main Salon and Upper Deck.

Additional components include:

• Denon tuner, CD and DVD player

• KVH two-way HD antenna

• Shipboard antenna, Starlin and cable TV

• A built-in 12-bottle wine cooler adds convenience for entertaining

Walking forward from the main salon, a few steps lead up to the pilothouse/command center, where you enter MAHANA’s gourmet galley—a signature feature of the SonShip 78’ series. Designed with the full functionality and welcoming feel of a “great room,” this spacious galley flows seamlessly into the pilothouse/command center, allowing the chef, helmsman, and guests to remain connected while entertaining, whale watching, or simply enjoying the scenery underway.

Mahana’s Gourmet Galley flows seamlessly into the yacht’s climate-controlled pilothouse and command center, creating a warm and highly social gathering. A spacious wrap-around settee upholstered in bold designer fabrics surrounds a beautiful Madrone Burl dining table with a stowable leaf, while abundant storage is thoughtfully integrated beneath the settee.

Hunter Douglas 2" blinds framed by fabric lambrequins, soffit lighting with dimmers, and rope accent lighting add warmth and visual depth, complemented by durable new Genuwood flooring that runs throughout both the galley and pilothouse. Striking Karadon countertops provide a bright and practical work surface, blending designer appeal with everyday functionality. The galley is turnkey and fully equipped with silverware, China, crystal and cookware that are secured in designated storage to protect delicate items while underway.

Galley Features Include:

•GE Profile full-size, side-by-side Refrigerator (New in 2019)

The Raised Pilothouse Command Center serves as MAHANA’s primary navigation station while also functioning as a comfortable gathering space when cruising or at anchor. The 78' SonShip’s spacious command center is designed to accommodate the latest electronics and navigational equipment, all beautifully integrated within finely crafted rift-cut American Cherry joinery. Two, custom Ultra Leather Stidd helm chairs are mounted side-by-side at the helm, providing exceptional comfort and excellent visibility while underway.

Just aft of the helm is a raised U-shaped settee, surrounding a hand-crafted American Cherry dinette table, with a Madrone Burl top. A removable and storable leaf allows the table to expand for additional seating. When the yacht is not underway, the two Stidd helm chairs rotate 180 degrees to face the table, adding two additional seats and transforming the pilothouse into a comfortable dining area where family and friends can gather.

Port and starboard pilothouse doors open directly to the yacht’s wide walk-around side decks, allowing easy access while docking or handling lines. The pilothouse doors have opening windows, along with Phantom screens concealed within the doors, and two overhead hatches with screens can be opened to provide natural light and fresh air throughout the space. A beautiful newly carpeted and Stainless-Steel staircase leads from the pilothouse to the flybridge above.

The flybridge features a fully equipped upper helm station, allowing the captain to operate the yacht comfortably while enjoying excellent visibility and open-air cruising. Twin helm chairs and a stainless-steel steering wheel provide confident control

Flybridge navigation equipment includes:

• Furuno radar and chart plotter displays 

• Engine monitoring instruments 

• Autopilot controls 

• VHF communications

The flybridge helm is fully integrated with the pilothouse electronics, providing redundancy and flexibility while underway. The helm layout offers excellent sight lines forward and to both beam directions, making docking, maneuvering, and passage-making intuitive from the flybridge. The flybridge also provides an expansive outdoor entertaining and command area with excellent visibility while cruising. A factory fiberglass hardtop with new Isinglass (full enclosure), updated in (2022,) provides protection from the elements while maintaining excellent visibility. The teak deck was re-seamed in (2022,) enhancing both appearance and durability.

The flybridge also includes: • 32"Samsung t 32" Samsung television, concealed in an overhead compartment that hinges down for viewing

MAHANA offers beautifully appointed accommodations designed for comfort and privacy for owners and guests. Throughout the yacht, the interior showcases rift-cut American Cherry joinery with Madrone Burl accents, complemented by custom designer fabrics, bedding, and décor curated by nationally award-winning ISD designer Cary Vogel.

Positioned along the wide walk-around side decks adjacent to the pilothouse doors, the wing stations give the operator excellent visibility of the dock, swim platform, and surrounding vessels, making close-quarters handling significantly easier.

MAHANA is equipped with an extensive exterior accent and underwater lighting system that can toggle between crisp bright white and a brilliant deep blue. The underwater lights illuminate the water surrounding the yacht, creating a dramatic nighttime presence both at anchor and in the marina. Achieving the perfect shade of blue was no small task—the owner spent nearly six months refining the color, resulting in the striking visual effect seen today.
