Artist’s concept of the new 2025 Neptunus 750SL

The Flagship of the Neptunus 750 Series, this Gregory C. Marshall-designed yacht delivers exciting new levels of form and function.

Her fully-enclosed skylounge is tastefully appointed with twin leather helm seats, state-of-the-art navigation electronics and a next generation helm. Access the skylounge from the interior of the yacht, or from an aft deck staircase. The skylounge offers outstanding visibility for piloting the yacht, and offers exquisite views and comfort while relaxing.

The new Neptunus 750SL features new design elements from bow to stern.

Experience natural walnut joinery with leather accents throughout the vessel. The full-beam master stateroom has sweeping windows and a walk-in cedar-lined closet. The salon offers a whole new level of comfort and pride. The galley has been designed with extended cruising in mind. And the new design touches from the creative mast atop the skylounge, to the bow area configuration for ground tackle and ropes, to the stylish blue LED deck lights and the backlit Neptunus logo will delight day and night.
