Engine Specifications:
Number of Engines: 2
Type: Diesel
Power Output: 800 HP each (total 1600 HP, equivalent to 1193 kW)
Efficiency at Low Froude Numbers:
At lower speeds (Froude numbers around 0.166), the vessel operates efficiently with minimal resistance. This speed range is ideal for extended cruising and maintaining fuel economy.
Planing Transition Zone:
At higher Froude numbers (approximately 0.331 to 0.497), the vessel enters a semi-planing regime. Resistance increases significantly, but the hull form is optimized to manage this transition effectively, reducing drag caused by wave-making.
High-Speed Performance:
At speeds approaching 20 knots (), the vessel exhibits a balance between semi-displacement and planing characteristics. However, this speed range requires higher power input, utilizing the full capacity of the twin 800 HP diesel engines.
Power and Resistance Estimation
The effective power required for maintaining 20 knots is estimated based on semi-displacement hull resistance calculations. Approximate thrust and resistance curves indicate that the combined output of the 2x 800 HP engines provides sufficient power to sustain the predicted speeds.
This 26.2 m semi-displacement motor yacht demonstrates efficient performance across a wide range of speeds. Its hybrid electric propulsion system, combined with the hydrodynamic efficiency derived from its coefficients, ensures excellent fuel economy and range for oceanic expeditions.

integrating electric and diesel motors.
Additionally, the motor yacht boasts a photovoltaic solar panel roof,
expandable up to 100 m2, delivering ample electric energy to cater to the
needs of multiple owners and guest families on board.
The interior arrangement spans three decks, with a focus on maximizing
interior volume.
