The OTG 20 represents the next step in the evolution of the original concept. It is conceived as a hybrid long-range motor yacht, designed for efficient and comfortable operation over extended distances, with a strong emphasis on owner autonomy and control. This design functions as a case study in which the integration of hybrid propulsion, energy management, and onboard comfort takes center stage. Rather than presenting fixed solutions, the concept explores how technology, layout, and use can be aligned to suit different cruising profiles, operating areas, and lifestyles. Every journey — and every owner — is different. For that reason, the OTG 20 is intentionally developed as a flexible platform. The concept can be adapted for extended passages, independent operation, and comfortable living aboard, without compromising calmness, clarity, or balance. The result is a carefully considered synthesis of adventure and comfort, shaped around how the owner chooses to experience the world.
