Greta Thunberg, TIME Magazine's Person of the Year, travelled from New York to Europe on the Malizia II, an elite racing yacht. This journey sparked controversy, as critics claimed that the yacht used more fuel than a commercial airplane would have for a similar trip. It is alleged that the yacht was powered by two diesel engines, consuming approximately 16 litres of diesel per hour. However, supporters of Thunberg's decision to sail instead of fly argue that her voyage was carbon neutral.

What You'll Learn
Greta's yacht used more fuel than a commercial plane
Greta Thunberg's yacht, the Malizia II, has been criticised for using more fuel than a commercial plane. The yacht is owned by Pierre Casiraghi, a member of Monaco's ruling Grimaldi family, and is described as an elite racing yacht. While the yacht is described as "green" and carbon neutral, critics have argued that it is not as environmentally friendly as it claims to be.
During winter, travelling from North America to Europe by boat requires a significant amount of fossil fuel. It is likely that the yacht used two engines to travel east across the Atlantic Ocean, burning more fuel than a flight from New York to Spain. Catamarans, in particular, cannot sail against the wind and require favourable wind conditions to do so.
The yacht's fuel consumption is estimated to be about 16 litres of diesel per hour for each engine, resulting in a total of 32 litres per hour. In comparison, a commercial plane would burn significantly less fuel over the same distance. For example, a Dassault Falcon 7X jet, engineered for fuel efficiency, burns only 4,000 pounds of fuel during its first hour of flight, and approximately 2,250 pounds per hour for the remainder of the trip.
Additionally, the size of the yacht also contributes to its fuel consumption. Larger yachts have higher fuel tank capacities and consume more fuel, especially when travelling at higher speeds. Greta's yacht, at 60 feet in length, would consume more fuel than a smaller yacht.
While the exact fuel consumption of Greta's yacht may vary depending on factors such as engine efficiency, hull design, and weight, it is clear that the claim of carbon neutrality may not be entirely accurate. The criticism highlights the importance of considering various factors when calculating fuel usage and the environmental impact of different modes of transportation.

The yacht likely used two engines
Greta Thunberg's yacht likely used two engines and more fuel than a commercial airplane to travel similar distances. The yacht in question is Malizia II, an elite racing yacht owned by Pierre Casiraghi, a member of Monaco's ruling Grimaldi family.
The yacht helped Greta protect the Earth from emissions from plane trips. However, it is important to note that the yacht likely used two engines to travel east at that time of year, burning more fuel than a flight from New York to Spain. Catamarans, in particular, cannot sail against the wind and can only do so if they are aided by favourable winds.
The amount of fuel a yacht consumes depends on several factors, including the size of the yacht, the speed at which it is travelling, the engine efficiency, hull design, and the weight carried by the yacht. For example, a 30-foot yacht may consume 15 litres of fuel per hour when cruising at 20 knots, but if the speed increases to 25 knots, the fuel consumption may reach 40-50 litres per hour.
The yacht Greta travelled on was a racing yacht, and such yachts are designed for speed rather than fuel efficiency. Therefore, it is likely that the yacht consumed a significant amount of fuel during its voyage, especially considering the distance travelled and the need to use two engines.
To reduce fuel consumption, yacht owners are advised to maintain their engines regularly, clean the hull, and plan sailing routes to avoid unfavourable conditions. However, even with these measures, a yacht with two engines travelling long distances can be expected to consume a considerable amount of fuel.

Greta's yacht is a large, racing yacht
Greta Thunberg's yacht, the Malizia II, is a 60-foot racing yacht. It was built for speed and conditions on the yacht range from basic to difficult. The boat has no kitchen, toilet, or shower, and no proper beds. The yacht is powered by sails, solar panels, and underwater turbines. The solar panels and underwater turbines are used for onboard electricity and lighting, while the sails are emblazoned with a 'Climate Action Now' message and Greta's signature call to 'Unite Behind The Science'.
The amount of fuel a yacht consumes depends on its size, purpose, and hull design. Greta's yacht is a racing yacht, which typically consume about 15 to 20 liters of fuel per hour at a cruising speed of 20 to 30 knots. However, if the speed increases, the fuel consumed also increases. For example, a 30-foot yacht cruising at 20 knots may consume 15 liters per hour, but if the speed increases to 25 knots, the fuel consumed may reach 40 or 50 liters per hour.
The Malizia II is a larger yacht at 60 feet, and it has been reported that it used more fuel than a flight from New York to Madrid. The yacht likely used two engines and burned more fuel than a commercial plane. The exact amount of fuel consumed by the Malizia II during Greta's voyage is not available, but it is estimated that a yacht with a diesel engine of 300 horsepower will burn 16-17 gallons of fuel per hour.
To reduce fuel consumption, yacht owners can regularly clean the hull and maintain the engine. Additionally, planning sailing routes to avoid headwinds and rough seas can help improve fuel efficiency.

Yacht fuel consumption depends on size, purpose, and hull design
Yacht fuel consumption depends on several factors, including the yacht's size, purpose, hull design, engine type, cruising speed, and the length of the journey.
Firstly, let's talk about the size of the yacht. Smaller yachts, typically those under 40 feet, consume less fuel and are more fuel-efficient than larger yachts. For example, a small 35-foot yacht has a fuel capacity of around 300 gallons and is designed for short voyages or coastal cruising. On the other hand, larger yachts, such as superyachts and mega yachts, have a much larger fuel capacity, ranging from 10,000 to 50,000 gallons, as they are built for long-distance sailing.
The purpose of the yacht also plays a role in fuel consumption. Yachts designed for long-distance sailing or cruising will have a higher fuel capacity and consumption than those designed for shorter voyages or coastal cruising.
Additionally, the hull design impacts fuel efficiency. Yachts with displacement hulls are more fuel-efficient at lower speeds, while yachts with planing hulls are more efficient at higher speeds. A clean hull improves fuel efficiency by reducing drag, and proper hull maintenance, including regular cleaning to prevent marine growth, is essential for optimal fuel efficiency.
The engine type and performance also influence fuel consumption. Diesel engines are more fuel-efficient than gasoline engines, and modern diesel engines may consume about 30% less fuel than gasoline engines. Well-maintained engines also contribute to better fuel efficiency, while operating a yacht at high speeds increases fuel usage.
Lastly, cruising speed and the length of the journey are critical factors. Each yacht has a speed range that is the most fuel-efficient, typically around 70%-80% of the maximum engine speed. Pushing the yacht to its maximum speed can dramatically increase fuel consumption. The longer the journey, the more fuel will be needed, and it is important to factor in additional fuel for unexpected changes or emergencies.
To estimate fuel consumption, one can calculate the fuel burn per hour based on engine horsepower and cruising speed. For example, a yacht with a diesel engine of 300 horsepower may burn 16-17 gallons per hour. Yacht owners can also use a yacht fuel cost calculator to estimate fuel costs by considering variables such as distance, cruising speed, fuel consumption, and fuel price.

Greta's yacht had a 672L diesel fuel tank
Greta Thunberg, the Swedish climate activist, travelled on a yacht with a 672L diesel fuel tank. The yacht, an Outremer 45, is made of fibreglass or fibre-reinforced plastic and weighs 17,400 pounds. It is powered by two Volvo diesel engines, which consume approximately four litres of diesel per hour each.
The amount of fuel a yacht consumes depends on several factors, including the size of the yacht, the speed at which it is travelling, the efficiency of its engine, its hull design, and the weight it is carrying. For example, a small 35-foot yacht with a fuel tank capacity of 300 gallons can be at sea for a few days at moderate speeds without needing to refuel. On the other hand, a superyacht or megayacht with a fuel capacity of 10,000 to 50,000 gallons can make long-distance voyages without refuelling.
To estimate the fuel costs for a yacht, one can use a yacht fuel cost calculator, which takes into account various variables such as the distance of the journey, cruising speed, fuel consumption, and the price of fuel. To reduce fuel consumption, it is recommended to maintain the yacht's engine regularly, plan sailing routes to avoid headwinds and rough seas, and keep the hull clean and free of marine organisms to reduce resistance.
While Greta's yacht had a relatively large fuel tank, the actual amount of fuel used during her trip is unknown. However, some have criticised her choice of transport, claiming that the yacht's diesel engines produce significantly more pollution than alternative modes of transport.
