Hull geometry, stability, and hydrodynamic performance
Adopt a long, slender hull with a bulbous bow and twin screws to minimize wave resistance and maximize range at cruise speeds. IPYD Studio unveils the 80m AETHER concept for Oceanco’s Simply Custom Range, built around open-water performance and easy handling as the vessel enter light seas smoothly. The hull uses marine-grade materials and light structural cores to keep weight down and balance favorable. approximately 80 m in length, waterline approximately 78 m, beam approximately 14.8–15.4 m, draft approximately 4.0–4.4 m under typical load. Ballast and structure are tuned to maintain a low gravity center while providing a stable platform for the captain.
Hull geometry centers on a long midbody with a bulbous bow and a refined entry to sustain laminar flow through the waterline. The waterline length supports a length-to-beam ratio around 5.0–5.5, keeping the hull stable at low heel. The sections shift gradually from bow to stern, with a gentle deadrise at the entry and a full stern that reduces pitching and keeps spray off the superstructure. An integrated stern fairing minimizes wake, improving propulsive efficiency and ensuring smooth passage in cross seas as the crew work the range.
Stability relies on a low center of gravity, ballast strategy, and an advanced hydraulic stabiliser system. The design uses iron ballast in submerged tanks to calibrate roll response, while the hydraulic stabilisers provide active damping during heavy weather. With light loads, initial GM targets around 1.2–1.5 m; in loaded configurations, GM remains within a comfortable 1.0–1.4 m. Active stabilisers can reduce roll motion by a substantial margin in typical sea states, giving the captain a steadier platform when the wake runs high and the waves grow tall.
Hydrodynamic performance follows a semi-displacement trajectory that benefits from a slender form, optimized entry, and stern fairing. CFD and tank tests show frictional drag representing roughly 40–60% of total resistance at 12–16 knots, with wave drag making up the remainder. At mid-range speeds, the Froude number sits near 0.22–0.28, indicating efficient propulsion without excessive hull vibration. The combination of a bulbous bow, refined midbody, and a tapered stern minimizes transom drag and promotes favorable stern lift, supporting stable, comfortable running at the higher end of the operating envelope.
Materials choices balance weight, stiffness, and corrosion resistance. The hull skin employs marine-grade aluminum alloys and carbon-reinforced composites, paired with corrosion-resistant fasteners and a robust internal lattice. For testing and validation, iron ballast provides a controllable baseline for roll and heel behavior, while the maker and native engineering teams iterate layouts to meet the Greek-inspired Artemis design sensibilities. The cost of this package reflects premium materials plus an integrated hydraulic-stabiliser system, but the anticipated fuel savings over the life of the yacht help justify the investment, especially as the crew and captain enter more demanding open-water cycles. The supply network supports a reliable launch window, with components sourced from a focused, international native supply chain to keep timelines aligned.
Propulsion, range, and speed targets for a mega yacht
Go with a hybrid diesel-electric propulsion package that allows 14-16 knots cruising and 6,000-7,000 nautical miles at 12-14 knots. This combination supports private itineraries with big guest groups while keeping fuel burn reasonable and maintenance predictable. The design path should prioritize reliability, ease service access, and a calm, predictable engine room experience that owners recognise as robust and flexible for fresh trips across coastal lanes or open-ocean passages.
Two m96l-class diesels with a robust battery bank and gensets form the hybrid core, enabling silent near-anchorage operation and high-load bursts for guests. This design mirrors Panther and Mangusta hull philosophies, focusing on stability, predictable trim, and efficient acceleration. The system allows easy access to critical components for maintenance, with modular power stages and native fault-tracing logic. The coach-friendly controls include browser-based dashboards and english-language manuals to support private owners and charter teams. The oceancos approach emphasizes modularity, making it easy to swap modules in august deliveries and keep the system current.
There are currently three performance bands that shape the targets: economic cruise at 12-14 knots delivering 6,000-7,000 nm; higher-speed transfer at 16-18 knots for coastal hops; and maximum speed capped at 21-23 knots for open-water transits when conditions allow. The hull and propulsors should maintain stability and moderate wakes, with variable-pitch or fixed-diameter propellers chosen to suit shaft layout. Noise at the transom must stay below 55 dB(A) during silent running in marina zones, enhancing guest comfort on the flybridge.
The deck layout provides a dedicated dinghy bay and a fishing-friendly aft cockpit, with a flybridge station that keeps the captain in sight of guests and a private access to the main salon. An owner suite and crew mess are designed for easy daily coach-style handovers, and the control suite uses a browser-based dashboard to monitor engine loads, battery state, and generator status. The flag and local regulations are easy to recognise thanks to the english language documentation and oceancos heritage that guides build choices. The result is a calm, inclusive experience for native crews on northern routes, guests, and owners alike, with a crazy smooth ride delivered by a Panther-like hull profile across a range of sea states.
Interior layout: owner’s suite, guest spaces, and service areas
Recommendation: position the owner’s suite as the midship hub, between the guest wing and the crew corridor, to minimize motion transfer and improve handling with stabilisers engaged. The hull profile supports a stable rate of motion, and August sun on the private veranda invites natural light into the space. This arrangement reflects dedication to privacy and a function-driven workflow for daily routines.
Owner’s suite specifics: about 150 m2 of private space featuring a king bed, spa bath, dressing area, and a private veranda. A dedicated port-side bureau supports personal work without intrusion from guest areas. The interior follows these specifications to ensure thermal comfort, acoustic isolation, and visual connection to the deck. The palette draws from santorini and grimaud inspirations, producing a calm but vivid well-lit environment suitable for long passages. These choices offer a refined backdrop for the owner’s portfolio and the m96l climate controls that handle crew routines while preserving quiet.
Guest spaces center on comfort and flexibility. The most used configuration offers four guest cabins that can switch between twin and double layouts. Each cabin includes an ensuite, ample storage, and daylighting through large hull-side windows. A guest lounge (about 40 m2) serves as a social area with a small island for tea service and cookies, enabling easy transitions between formal and casual moments. These spaces are positioned to balance privacy with sociability, between the owner’s wing and the crew corridor, while ensuring ample circulation around the core modules.
