Fuel is one of the most significant annual running costs of a superyacht. The cost of fuelling a superyacht depends on several factors, including the distance of the journey, the cruising speed, fuel consumption, and the price of fuel per litre or gallon. An average 70-metre luxury yacht, for example, burns around 130 gallons of fuel per hour with its engines running, and this increases significantly when the yacht is in motion. The cost of fuel also varies depending on the marina or country. The fuel capacity of a superyacht is determined by factors such as the vessel's size, engine type, and intended usage, with larger yachts typically having larger fuel tanks to support long-range travel. Implementing a Ships Energy Efficiency Management Plan (SEEMP) can help reduce fuel costs without compromising the cruising experience.

What You'll Learn
Fuel is a yacht's biggest expense
The cost of yacht fuel varies depending on location and market conditions, with marine fuel pricing being heavily inflated due to low supply and high demand. On average, a 70-metre luxury yacht will burn around 130 gallons of fuel per hour with its engines running, and this increases significantly when the yacht is in motion. The faster the yacht travels, the more fuel it burns, and the more expensive each hour becomes.
There are a number of factors that influence a yacht's fuel efficiency and, therefore, its overall fuel costs. Firstly, the size of the yacht's fuel tanks is crucial in determining its cruising range and efficiency, with larger yachts typically having larger tanks to support long-range travel. The engine type and intended usage of the yacht will also affect the size of its fuel tanks. Yachts with planing hulls, for instance, which are designed for high speeds, will require more fuel to achieve and maintain speed.
The weight of onboard cargo and passengers will also impact fuel consumption, as will the sea conditions. Strong headwinds, currents, and rough seas can force the engine to work harder, increasing fuel usage. Additionally, the more often a yacht uses its generators, the higher its fuel consumption will be. This is because yachts running on generators for most of the time will consume more fuel than those that can connect to shore power and water in a marina at night.
To reduce fuel costs, yacht owners can implement a Ships Energy Efficiency Management Plan (SEEMP). This helps to keep fuel costs down without compromising the cruising experience. Proper hull maintenance, including regular cleaning to prevent drag from marine growth, can also improve fuel efficiency.

Fuel cost depends on distance, speed, consumption, and price per litre
Fuel costs for a superyacht depend on a variety of factors, including distance, speed, fuel consumption, and price per litre.
Distance
The total distance of the journey is a key factor in determining fuel costs. A longer voyage will naturally require more fuel than a shorter one. The distance travelled is measured in nautical miles, and this information is used to calculate fuel consumption and overall fuel costs.
Speed
The cruising speed of the yacht also plays a significant role in fuel consumption. Operating a yacht at high speeds increases fuel usage. Most yachts have an optimal cruising speed, often referred to as the fuel-efficient range, where consumption is more balanced. For example, a 30-metre yacht cruising at 20 knots will consume approximately 400-500 litres of fuel for a distance of 100 nautical miles. On the other hand, a 70-metre yacht travelling the same distance but burning 1,000 litres per hour will consume a total of 8,335 litres.
Fuel Consumption
Fuel consumption is influenced by various factors, such as the size and type of engine, the use of generators, and the number of tenders and water sports equipment on board. The weight of onboard cargo and passengers, as well as sea conditions like headwinds, currents, and rough seas, can also impact fuel consumption, as they affect how hard the engine must work.
Price per Litre
The cost of fuel per litre varies depending on the location and market conditions. Bunkering in different countries will result in different fuel prices, and some places, like Gibraltar and Montenegro, offer tax-free fuel. The type of fuel also affects the price, with diesel being the preferred fuel for yachts due to its better efficiency.
To estimate the total fuel costs for a superyacht journey, one can use a yacht fuel cost calculator, taking into account the distance, speed, fuel consumption, and price per litre.

Yachts use more fuel at high speeds
Yachts are luxurious vessels that offer a unique cruising experience. However, their fuel consumption can be a significant expense, with fuel costs varying based on several factors. One critical factor is speed; yachts tend to use more fuel when cruising at higher speeds.
A yacht's fuel consumption is influenced by various factors, including engine type, size, and maintenance. Well-maintained engines run more efficiently, burning less fuel. Additionally, the yacht's itinerary and sea conditions play a role in fuel usage. Smooth and calm waters enable more efficient travel, whereas strong headwinds, currents, and rough seas demand more power and fuel.
The hull shape of a yacht also impacts fuel efficiency. Displacement hulls, commonly found on long-range cruisers, are more fuel-efficient at lower speeds, whereas planing hulls, used in high-speed yachts, require significantly more fuel at higher speeds. This is because, as speed increases, boats experience increased resistance in the water, necessitating more power and fuel.
To illustrate, consider a 30-metre yacht cruising at 20 knots, which consumes approximately 400 to 500 litres of fuel, depending on the engine. In contrast, a 70-metre yacht travelling at the same speed but burning 1000 litres per hour would consume 8335 litres for the same 100-nautical-mile journey. This highlights how larger yachts, particularly at higher speeds, can quickly exceed 100 gallons of fuel per hour.
To optimise fuel efficiency, yacht owners should identify and maintain the hull speed, keep the engine and hull well-maintained, and plan direct routes that consider sea conditions. Implementing a Ships Energy Efficiency Management Plan (SEEMP) can also help reduce fuel costs without sacrificing the cruising experience. By considering these factors, yacht owners can enjoy a more sustainable and cost-effective journey.

Yachts at anchor use more fuel
Yachts are luxurious vessels that require fuel not only for cruising but also for the generators that keep the vessel running while at anchor and underway. Fuel is one of the major annual expenses for yacht owners and captains, and it is estimated that the global spend on yacht fuel is around $150 billion annually.
The amount of fuel a yacht consumes depends on several factors. Firstly, the size and make of the engines play a role, with larger and more powerful engines typically consuming more fuel. Secondly, the frequency of generator usage impacts fuel consumption, as yachts running on generators 90% of the time while at anchor will use significantly more fuel than those connected to shore power and water at a marina. Thirdly, the number of tenders and water sports equipment on board that require fuel can increase consumption. Additionally, the yacht's itinerary and sea conditions will affect fuel usage, with engines burning more fuel in certain conditions.
To estimate the fuel costs for a yacht, several variables need to be considered. The distance of the journey, measured in nautical miles, and the cruising speed of the vessel in knots are important factors. The fuel consumption rate of the yacht's engines, typically measured in gallons or litres per hour, is also crucial. Finally, the average market price per gallon or litre of fuel must be taken into account.
For example, let's consider a 70-metre luxury yacht. With its engines running, such a yacht would burn around 130 gallons of fuel per hour, and this increases significantly when the yacht is in motion. To achieve a speed of 20 knots, the fuel cost would be approximately €2000 per hour (±1000 gallons). The higher the cruising speed, the more fuel is burned per hour, making each hour at sea more expensive.
To optimise fuel efficiency and reduce costs, yacht owners can implement a Ships Energy Efficiency Management Plan (SEEMP). This helps to minimise costs and reduce the environmental impact of burning unnecessary fuel. Proper maintenance of the yacht's engines and hull is also crucial, as well-maintained engines run more efficiently and hull maintenance improves fuel efficiency.

Fuel prices vary by location
The price of fuel also depends on the type of fuel and the engine's octane rating. High-performance vessels such as speed boats require higher octane gas, which can be $0.02 to $0.05 more per gallon. Additionally, marinas and boat-related businesses tend to be seasonal, leading to higher prices at certain times of the year.
The size of the yacht and its fuel economy also impact the overall fuel cost. A yacht measuring 45 feet or more will require diesel fuel, and a larger yacht will consume more fuel. For example, an average 70-metre luxury yacht will burn around 130 gallons of fuel per hour with its engines running, costing approximately $468 to $585 per hour at $3.60 to $4.50 per gallon.
The cruising speed of the yacht also affects fuel consumption and cost. A yacht travelling at 20 knots will consume more fuel per hour than one travelling at 10 knots. Additionally, the yacht's itinerary and sea conditions will impact fuel consumption, as will the use of generators and water sports equipment.
Overall, the location of fuel purchases, fuel type, engine specifications, yacht size, cruising speed, itinerary, and onboard equipment all influence the varying fuel prices for superyachts.
