Feasibility of Hybrid Drives for Yachts with Surface Drives

The combination of hybrid propulsion and surface drive system is a feasible solution for enhancing the efficiency, comfort, and environmental sustainability of yachts. Here are the reasons why:

The surface drive system reduces water resistance and rotational inertia, thus improving the propulsion efficiency of the yacht. The hybrid propulsion system, on the other hand, utilizes electric motors to provide power at low and medium speeds, which can better match the propulsion characteristics of the partial immersion propeller.

The hybrid propulsion system can automatically adjust the proportion of electricity and fuel consumption according to the propulsion demands, achieving a more efficient propulsion. At low and medium speeds, the electric motors provide the primary propulsion power, which significantly reduces fuel consumption and emissions. At high speeds, the surface drive and partial immersion propeller provide the primary propulsion power, improving the speed and stability of the yacht.

The electric motors of the hybrid propulsion system have low noise, low vibration, and high efficiency, which can enhance the comfort and smoothness of the yacht. Additionally, through energy recovery technology, the electric motors can convert braking energy into electrical energy and store it in batteries, further improving the energy efficiency of the yacht.

Overall, the combination of hybrid propulsion and surface drive system is an effective propulsion system that offers a more efficient, comfortable, and sustainable yachting experience. With the continuous development of battery technology and the reduction of costs, the application of hybrid propulsion systems is becoming increasingly widespread.
