Overview
Diesel fuel is one of the most common types of fuel used in yachts, particularly for motor yachts and larger vessels. Diesel engines are favored for their reliability, efficiency, and longevity. Diesel fuel is available in two primary grades: Marine Diesel Oil (MDO) and Marine Gas Oil (MGO).
Marine Diesel Oil (MDO)
Marine Diesel Oil is a blend of diesel fuel and a small percentage of distillate oil. It is used primarily in larger vessels and is known for its good combustion properties and reduced soot emissions compared to traditional fuels. MDO is suitable for medium-speed marine engines and provides a balance between performance and environmental impact.
Marine Gas Oil (MGO)
Marine Gas Oil is a higher-quality, more refined form of diesel fuel that is used in both high-speed and medium-speed marine engines. MGO has a lower sulfur content than MDO, which helps reduce harmful emissions and is compliant with more stringent environmental regulations. It is often used in situations where cleaner emissions are a priority.
Advantages of Diesel Fuel

Considerations for Diesel Fuel
Emissions: While diesel engines are efficient, they can produce higher levels of nitrogen oxides and particulate matter, which can be a concern for environmental regulations.
Maintenance: Diesel engines require regular maintenance, including fuel filter changes and periodic inspections, to ensure optimal performance and longevity.
Gasoline
Overview
Gasoline is commonly used in smaller yachts, such as sport boats and recreational craft. It is known for its ease of use and relatively lower cost compared to diesel. Gasoline engines, however, are generally less efficient and durable than their diesel counterparts.
Advantages of Gasoline
Cost-Effective: Gasoline is often less expensive than diesel fuel, making it a more economical choice for smaller vessels.
Power-to-Weight Ratio: Gasoline engines typically have a higher power-to-weight ratio, which can enhance performance and acceleration in smaller yachts.
Lower Emissions: Gasoline engines generally produce fewer particulate emissions compared to diesel engines.
Considerations for Gasoline
Flammability: Gasoline is more flammable than diesel fuel, which necessitates careful handling and storage on yachts.
Efficiency: Gasoline engines tend to be less fuel-efficient than diesel engines, which can lead to higher fuel consumption over time.
LPG (Liquefied Petroleum Gas)
Overview
Liquefied Petroleum Gas (LPG) is a blend of propane and butane, used primarily for cooking and heating on yachts rather than for propulsion. LPG is stored in pressurized tanks and is favored for its clean-burning properties.
Advantages of LPG
Clean Burning: LPG burns more cleanly than gasoline and diesel, producing fewer emissions and residues.
Convenience: LPG can be used for various onboard applications, including cooking, heating, and hot water systems.
Efficiency: LPG is efficient in terms of energy output per unit of fuel.
Considerations for LPG
Storage: LPG requires specialized, pressure-rated storage tanks and proper ventilation to prevent leaks and ensure safety.
Limited Use: LPG is not typically used for propulsion but rather for auxiliary functions on yachts.
Renewable Fuels
Overview
With growing environmental concerns, renewable fuels are becoming an increasingly important option for yachts. These include biofuels and synthetic fuels that aim to reduce the environmental impact of marine travel.
Biofuels
Biofuels, such as biodiesel and bioethanol, are derived from organic materials and can be used as alternatives to traditional diesel and gasoline. Biodiesel, for example, is made from vegetable oils or animal fats and can be used in diesel engines with minimal modifications.
Synthetic Fuels
Synthetic fuels, including synthetic diesel and methanol, are produced from non-fossil sources and offer a cleaner alternative to traditional fuels. They can be designed to meet specific environmental standards and reduce greenhouse gas emissions.
Advantages of Renewable Fuels
Environmental Benefits: Renewable fuels often have a lower carbon footprint and produce fewer pollutants compared to conventional fossil fuels.
Sustainability: Using renewable fuels can contribute to a more sustainable yachting industry and reduce dependence on fossil resources.
Considerations for Renewable Fuels
Availability: Renewable fuels may not be as widely available as traditional fuels, which can impact their practicality for long voyages.
Compatibility: Some renewable fuels may require modifications to existing engines or fuel systems.
Choosing the Right Fuel for Your Yacht
Selecting the appropriate fuel for your yacht involves considering several factors, including the type of vessel, intended use, and environmental considerations.
Type of Vessel
The size and type of yacht play a significant role in determining the appropriate fuel. Larger yachts and motor yachts typically use diesel fuel due to its efficiency and power, while smaller recreational boats may use gasoline. Auxiliary fuels like LPG are commonly used for non-propulsion purposes on both types of vessels.
