Hypercar Lines, Superyacht Lifestyle: Delta Marine’s New 125’ Longtail Concept
Hypercar-inspired lines meet alfresco living in Delta Marine’s new 125’ Longtail superyacht concept, designed around outdoor social spaces.
American builder Delta Marine and Italian designer Roberto Curto have teamed up to launch their new bold and contemporary longtail 125’ (38m) superyacht concept that focuses on outdoor living.
Sleek flowing lines and a design inspired by longtail hypercars, according to the builder, the yacht combines aerodynamic form with practical social spaces. The contrast between a white hull and a dark superstructure balances sophistication with this playful, dynamic profile.
All Eyes On Aft
The most eye-catching feature of this concept is its elongated aft, a design choice that creates a visually intriguing profile while also serving a practical purpose. An area that is the heart of onboard socializing, relaxing, and entertaining, it features lounging areas, dining, and even a flexible dance floor. Here, there is also an oversized pool leading to the beach club area for access to the water’s edge.
Every detail on the yacht concept emphasizes days spent on the water, bringing the feel of Italy’s coastal lifestyle onboard.

Outdoor Living, Everywhere
The vision for this superyacht goes further than the aft, spanning the entire yacht. There are open-air lounges on the upper deck and bow, offering intimate relaxation spaces and panoramic views.
With an emphasis on natural light and easy transitions between indoor and outdoor areas, the layout is focused on alfresco living.
Contemporary And Natural Interiors
Inside, the yacht can accommodate up to 10 guests across five cabins. Interior details include large, rounded windows in social areas and lower-level windows in guest suites to maximize light-filled spaces, comfort, and privacy.
When it comes to aesthetics, the renderings currently showcase contemporary, neutral, and soft brown palettes with natural textures, including organic wall coverings in the skylounge—interiors that ideally complement the Longtail’s outdoor-focused lifestyle.
Delta Marina’s and Curto’s Longtail superyacht concept highlights this ongoing shift in prioritizing versatile social spaces and outdoor living. A yacht that promises a lifestyle statement that can combine elegance and innovation with leisurely days on the water into one intriguing platform.
