Fuel economy: trawlers are fuel-efficient, but marine engines are inefficient
Trawlers are relatively fuel-efficient, especially full displacement trawlers. A Northern Marine or other full displacement trawler yacht with a single engine can provide a steady cruising speed that yields between 1.5 to 2.5 nautical miles per gallon of fuel. This is considered good fuel economy for a large yacht capable of travelling anywhere in the world.
However, the fuel economy of trawlers varies depending on their size, hull shape, and engine type. For example, a 45-foot boat with a 135 HP engine burns 2 gallons of fuel per hour at 7 knots (3.5 nautical miles per gallon). At 8 knots, the fuel burn increases to between 3.5 and 3.7 gallons per hour, which is less efficient.
The speed of a trawler also affects its fuel efficiency. Slowing down can improve fuel economy, with some trawlers achieving better mileage at 6 knots than at higher speeds. Additionally, hull efficiency varies among different hull shapes, with each having its own positive and negative elements.
While trawlers can be fuel-efficient, marine engines are generally inefficient compared to other types of engines. They have low miles per gallon (MPG) and produce high emissions. For example, a 40-foot trawler cruising in the Caribbean may achieve only 1 MPG, which is considered relatively good for a boat of that size.
When considering fuel economy for cruising the Caribbean, it is important to factor in the distance travelled, the size of the fuel tanks, and the availability of cheap fuel. For long-range cruising and open water safety, larger diesel tanks are recommended. Stabilization systems and twin engines can also be advantageous for cruising in the Caribbean.

Fuel burn rates: the rate varies depending on the boat and engine
The fuel burn rate of a boat depends on several factors, including the boat's hull shape, length, total weight, and drag. The engine's horsepower, propeller configuration, and number of engines also play a role in fuel consumption.
A full-displacement trawler in the 40- to 50-foot range typically achieves better fuel economy at slower speeds. For example, at 7.5 knots, it burns 3 GPH, resulting in 2.5 nMPG. However, when the speed is increased to 9 knots, the fuel burn rate jumps to 11 GPH, reducing the efficiency to 0.8 nMPG.
The hull shape also significantly impacts fuel economy. Full displacement, semi-displacement, and planing hulls respond differently to speed demands. For instance, a semi-displacement boat in the same size range as the full-displacement trawler mentioned above burns 3.4 GPH at 8.5 knots, achieving 2.2 nMPG. But when the speed is increased to 10.5 knots, the fuel burn rate increases to 14.2 GPH, resulting in a significantly lower efficiency of 0.74 nMPG.
The number of engines can also affect fuel consumption. In some cases, twin engines may burn less fuel than a single engine, depending on the horsepower and propeller configurations. For example, two smaller engines of 220 hp each require less horsepower from each engine to reach 15 knots compared to a single engine. As a result, they may burn less fuel per engine at the required RPM for this speed.
Additionally, the type of engine and fuel used influence the fuel burn rate. On average, a well-maintained diesel engine burns about 0.4 pounds of fuel per hour for each unit of horsepower, while an in-tune four-stroke gasoline engine burns about 0.50 pounds per hour. Diesel fuel typically has higher energy content, with #2 fuel oil containing 30% more BTU per gallon than gasoline.
When planning a long-distance cruise, it is essential to consider the boat's fuel economy and range. Fuel consumption can be estimated using formulas or by referring to boat fuel consumption charts or fuel consumption monitors.

Cost of fuel: the price of diesel fuel spiked in the past
When it comes to cruising the Caribbean in a trawler, fuel economy is not a major concern for most. Trawlers carry a lot of fuel in their tanks and burn relatively little fuel, making them perfect for long-distance cruising. However, the cost of fuel is an important consideration for those planning extended cruises.
The price of diesel fuel has seen spikes in the past, such as the record-breaking increase in 2022, where the price of diesel fuel rose by 55% from January to June. This spike prompted a discussion among trawler dealers about the cost of cruising, comparing the fuel efficiency of slower, semi-displacement models to faster, planing models.
The cost of fuel for a cruise ship can range from $80,000 to $200,000 per day, with fuel being one of the largest expenses. For example, Royal Caribbean's Harmony of the Seas spends about $200,000 per day on fuel, while a cruise ship with 1000 passengers and 700 crew members may spend about $15,000 a day. These costs are then passed on to the customers, affecting the price of a cruise ticket.
For those planning to cruise the Caribbean in a trawler, it is recommended to have large-capacity diesel tanks to enable long-range cruising and take advantage of cheap fuel prices when available. The size of the trawler is also an important consideration, with larger vessels providing more comfort and tank capacity, making them better suited for open ocean voyages. Stabilization is also advisable for cruising in the Caribbean Sea, especially for displacement-style cruisers, to improve fuel economy and range.
While the cost of fuel may not be a primary concern for all cruisers, the impact of fuel price spikes can be significant, affecting both the cruise industry and those planning private cruises.

Fuel capacity: larger trawlers have larger tanks, but fuel capacity is also influenced by the type of engine
Trawlers are typically offered in lengths ranging from 35 to 60 feet, with some even exceeding this maximum length. They are built for long-term cruising and can accommodate between 2 and 8 persons for extended periods, even serving as a permanent home for some.
Trawlers usually have large fuel tanks and can cruise for a long time before needing to refuel. Their fuel capacity is influenced by the type of engine and the size of the trawler. For instance, the Northern Marine 57 has a 2,600-gallon fuel capacity, while a Monk 36 carries 300 gallons of fuel. The fuel capacity of a trawler is crucial for long-range cruising, as it enables you to buy fuel when it is cheaper and avoid the need for frequent refuelling, which can be inconvenient, especially when cruising in remote locations.
Recreational trawlers, which resemble fishing trawlers, usually have smaller engines compared to their fishing counterparts. An 80 hp engine can be adequate for a 42-foot recreational trawler, and it will use less than 25 hp to cruise. These trawlers often have a cruising speed of 7-9 knots, with a maximum speed of 10-12 knots. The slower speed of displacement hulls results in lower fuel consumption, making them a popular choice despite the trade-off in speed.
When considering a trawler for cruising the Caribbean, it is recommended to opt for a larger vessel, ideally in the 45-foot range, to provide more comfort and space for guests. Stabilization is also advisable for cruising in the Caribbean Sea, and a twin-engine setup adds redundancy and makes berthing easier. The choice between a single or twin-engine configuration will impact the fuel capacity and overall fuel efficiency of the trawler.
Overall, the fuel capacity of a trawler yacht is an important consideration, and larger trawlers with larger tanks and efficient engines can provide a significant range, making them well-suited for long-distance cruising in the Caribbean.

Fuel type: some fuels are cheaper but face scrutiny due to their environmental impact
When it comes to choosing fuel for cruising the Caribbean in a trawler, there are various factors to consider, including cost, availability, and environmental impact. While diesel is commonly used for trawlers and can be a cost-effective option, it's important to be mindful of the environmental implications of different fuel types.
Heavy Fuel Oil (HFO), for instance, is widely used in the maritime industry due to its relatively low cost, typically 30% cheaper than distillate fuels such as marine diesel oil or marine gas oil. However, HFO has come under scrutiny due to its high Sulphur oxide emissions, which have negative environmental and health impacts on port communities. To address this issue, the International Maritime Organization (IMO) implemented regulations in 2020, limiting Sulphur emissions to 0.5%. As a result, ship operators have had to adopt measures such as installing marine scrubbers to reduce Sulphur oxide emissions when using HFO.
As an alternative to HFO, ship operators can consider ultra-low Sulphur fuels, such as Marine Gas Oil (MGO) and Marine Diesel Oil (MDO). These fuels are created through a refining process and offer a more environmentally friendly option by meeting the IMO's Sulphur cap limit. However, they may come with certain disadvantages, such as sensitivity when mixed with other fuels and the risk of instability. Additionally, the cost of retrofitting vessels to use alternative fuels, such as liquid natural gas, can be a significant consideration for ship operators.
When planning a cruising trip in the Caribbean, it's essential to factor in fuel efficiency and consumption. Trawlers are known for their fuel efficiency, burning relatively little fuel, which makes them suitable for long-distance cruising. However, the fuel consumption of any vessel depends on various factors, including engine type, speed, load, and hull design. High speeds result in higher fuel consumption, while adopting a more moderate cruising speed can help conserve fuel. Additionally, overloading a boat can decrease performance and increase fuel usage. Understanding the fuel efficiency of your trawler and planning a direct route can help you estimate fuel costs and ensure a more environmentally conscious journey.
In conclusion, while cost and efficiency are crucial considerations when choosing a fuel type for cruising the Caribbean in a trawler, it's essential to be mindful of the environmental impact of different fuels. By selecting fuels with lower Sulphur content, such as ultra-low Sulphur distillates or exploring alternative fuel sources like liquid natural gas, ship operators can reduce their environmental footprint. Additionally, adopting fuel-saving practices, such as moderate speeds and efficient route planning, can further minimize the environmental impact of cruising in the Caribbean.
