Sealine S390Experience this SUNSATION!
The SEALINE S390 not only feels like a convertible, ideal for celebrating summer at sea – it also offers you outstanding volumes! Enjoy the largest cockpit in its class, more than 4.5 square meter of lounging space on the foredeck, an XL bathing platform and up to three galley units on deck. All bathed in sunlight as soon as the two sunroofs are open. No wonder we’re calling it a SUNSATION! And if the summer does take a break, the elegant interior comes into its own. Adapt the layout below deck to give you every comfort.
Exterior Design
SEALINE yachts amaze with their modern, functional design. Unique, puristic elegance meets exceptional performance from the pen of Bill Dixon, one of the world’s best and most experienced yacht designers.


















Barbecue right on the sea
The exterior grill at the stern makes every barbecue an experience in itself. Without taking a step, you pass the grilled delicacies directly to family and friends in the cockpit. This feature includes a gas grill, wet bar, work surface and separate LED lighting.
Biggest cockpit in its class
The smart arrangement of the L-shaped sofa and table creates unparalleled free space. Choose from a fixed or adjustable cockpit table and backrest. The latter option turns the cockpit into a sun terrace.
Comfortable XL- Bathing platform
An irresistible summer yacht like the SEALINE S390 needs a bathing platform with all the comforts. Opt for an extra-long, hydraulic platform, while a stainless-steel bathing ladder and warm deck shower come as standard.
Two sunroofs in 4 variations
Above the steering position and the galley units, we offer two sliding glass sunroofs as standard. For maximum sunlight, choose the electric soft-top. A manual or electric soft-top is also possible above the cockpit.
Interior design
Thanks to various layout variants and a large selection of combination options – with high-quality fabrics, fine woods, trendy colours, select floorings and stylish furnishings – you can make your SEALINE your own, a very personal one-of-a-kind yacht.









First-class owner’s cabin
Twin wardrobes, king-size island bed, and private access to the bathroom make for exquisite comfort, featuring excellent craftsmanship and the highest manufacturing standards.
Sophisticated lighting design
When the sun goes down, a perfectly balanced lighting concept sets the scene for the interior aesthetics. Clever indirect lighting accentuates the shape of the spaces below deck and creates an engaging, harmonious atmosphere.
Personalised interior layout
On the starboard side amidships, SEALINE will build your chosen layout. Options include: a galley with microwave, storage space fitted out with cupboards, or a double-sized bathroom with a separate shower cubicle.
Daylight from four directions
Long hull windows, front windows, skylights - the ambience of the owner's cabin emerges from the interplay between fine woods and sunlight, which streams in from all sides to make it as bright as day.
