Four Dimensions of Hybrid Excellence
The Gottsegen 115 Superyacht is a 35-meter (115 ft) luxury explorer superyacht concept engineered for long-range cruising, featuring a modern plumb bow, dynamic profile, and high-volume multi-deck architecture.
Exterior & Layout Highlights
* Hull & Superstructure: Navy blue hull paired with a metallic gunmetal superstructure, high freeboard, and continuous panoramic window ribbons.
* Aft Deck & Beach Club: Expansive teak swim platform with integrated dual-stair access leading to the main deck aft cockpit.
* Upper Deck Lounge: Features a large circular Jacuzzi/spa pool, surrounded by circular outdoor dining and open sun-lounging space.
* Sundeck / Flybridge: Semi-enclosed sky lounge topped with a sleek hardtop, housing communication domes, an open-air wet bar, and high-top seating.
* Foredeck: Sunbathing platform with integrated seating forward for panoramic views at anchor.
Main Engine Configuration
| Specification | Details |
| Engine Model | Twin CAT C32B V12 Twin Turbo Diesel |
| Power Output | 2,000 BHP (1,491 bkW) @ 2,300 RPM per engine (4,000 BHP total) |
| Displacement | 32.1 Liters |

| Key Features | ADEM VI electronic controls, MEUI-C fuel system for low-speed noise reduction, and high power density |
Optional Hybrid Propulsion System Integration
The vessel offers an optional parallel hybrid propulsion package designed for seamless compatibility with CAT marine engines and control networks:
* Parallel Hybrid Drive (PTI/PTO): Compact permanent-magnet electric motor-generators (EMG) mounted inline between the CAT C32B engines and shaft reduction gearboxes via remote disengaging clutches.
* Zero-Emission Electric Mode: Allows low-speed (6–9 knot) silent cruising on battery power alone—eliminating engine noise, vibration, and exhaust emissions during night runs or sensitive marine park transit.
* Power Take-Off (PTO) Mode: Utilizes main engine power during long passage-making to generate electrical power, charging the high-voltage Lithium-ion battery bank without running auxiliary diesel generators.
* Power Boost Mode (PTI): Combines full torque from the 2,000 BHP CAT engines with electric motor assistance for rapid acceleration or top-end performance.
* Extended Service Life: Reduces total running hours on main engines and generators, optimizing fuel burn and lowering long-term maintenance cycles.
The optional ZF Marine Hybrid Transmission Series (3000, 5000, and 9000 PTI) manages power flow across four primary operational modes using integrated dual hydraulic clutches and electronic control synchronization over CANbus:
1. Pure Electric / Zero-Emission Mode (PTI)
* Clutch State: Main diesel clutch Disengaged | PTI electric motor clutch Engaged.
* Power Flow: The liquid-cooled permanent magnet electric motor drives the propeller or waterjet directly via the integrated PTI spur gear reduction stage.
* Application: Silent harbor maneuvering, low-speed transit in emission-restricted coastal zones, and zero-noise night operations.
* Key Advantage: Zero direct exhaust emissions, drastically reduced acoustics, and maximum instantaneous low-end torque.
2. Conventional Diesel Mode
* Clutch State: Main diesel clutch Engaged | PTI electric motor clutch Disengaged.
* Power Flow: Main diesel engine (e.g., Caterpillar V12) delivers power directly through the main reduction gear train to the shaft line or waterjet.
* Application: High-speed open-water cruising and long-range transits at standard cruising speeds.
* Key Advantage: Pure mechanical drive efficiency with zero power conversion losses.
3. Booster / Hybrid Mode (Diesel + Electric)
* Clutch State: Main diesel clutch Engaged | PTI electric motor clutch Engaged.
* Power Flow: Both power sources drive the output shaft simultaneously. The electric motor injects supplementary boost power (150 kW up to 750 kW depending on unit size) into the reduction gear train alongside main engine power.
* Application: High-speed sprint bursts, overcoming heavy hull resistance, fast acceleration, and emergency maneuvering.
* Key Advantage: Delivers peak transient performance without requiring oversized primary diesel engines.
4. Generator / Battery Regeneration Mode (PTO)
* Clutch State: Main diesel clutch Engaged | Electric machine connected in Generator Mode.
* Power Flow: While propelling the vessel, the main diesel engine simultaneously drives the permanent magnet machine as a shaft generator via the PTI gear interface. ZF power electronics convert and regulate AC power to charge energy storage systems or feed hotel electrical loads.
* Application: Recharging main battery banks while under transit without running auxiliary diesel generators.
* Key Advantage: Optimizes main diesel engine loading (preventing low-load soot accumulation) and drastically lowers total generator fuel consumption and maintenance hours.
Operation Matrix
| Mode | Main Diesel Engine | Electric Machine State | Propulsion Power Source | Electrical Grid Impact |
| Pure Electric | Off / Disengaged | Motor Drive | Electric Motor | Battery Discharge |
| Conventional | Running / Engaged | Disengaged / Idle | Main Diesel Engine | Aux Generators Active |
| Booster | Full Power | Motor Drive | Diesel + Electric Combined | Battery Discharge |
| Generator (PTO) | Running | Generator Drive | Main Diesel Engine | Battery Charging / Hotel Load |
Noble Navigation
The Philosophy of Silence
Our vision is based on treating the world's oceans with respect. With the whisper-quiet electric drive, you glide through sensitive coastal ecosystems and untouched bays without leaving a trace.
The combination of cutting-edge solar technology and high-capacity battery storage makes it possible to travel independently at the highest level, without disturbing the marine environment with noise or emissions.
