On average, a yacht uses between 20 to 100 gallons of fuel per hour. Smaller yachts, such as those around 40 feet, tend to be on the lower end of the scale, consuming about 20 to 40 gallons per hour. A standard boat gets around 3 mpg (miles per gallon) at MAX RPMs. However, the mileage can vary from as small as 0.5 mpg or less to as high as 8 mpg or more depending on the weather condition, boat weight, and other factors.
To calculate your vessel’s yacht fuel cost, use a yacht fuel cost calculator to get an estimate. The efficiency of boat fuel is measured in pounds of fuel used in an hour per horsepower. Gasoline is almost 6.1 pounds per gallon while diesel is 7.2.
Larger luxury yachts, such as superyachts, consume around 20 to 50 gallons of fuel per hour at cruising speed. A vessel with a diesel engine of 300 horsepower will most likely burn 16-17 gallons per hour, which can be used as a guideline when calculating travel time based on the nautical miles you are looking to cover. Superyachts are consuming much more fuel, with an average 70-meter luxury yacht burning around 130 gallons per hour.
Offshore sailing yachts consume approximately 2 to 5 liters of oil per hour, depending on the size of the yacht and engine capacity. For example, a small 30-foot yacht with a 25hp engine will consume about 2 liters per hour. A 40-ft planing boat burns about 25 gph at 20 knots, while a square-sterned displacement boat like a Grand Banks will burn 3 gph at 7 knots and 10 gph at 8.5 knots. A Monterey fishing boat with a 3 cylinder Yanmar diesel will use about 1 gallon an hour at 1800 RPM.
The distance a yacht can travel varies based on its size, engine power, and fuel capacity. A typical 35-foot motor yacht can usually go 200-300 miles in a day if it keeps a good pace. Bigger yachts for long journeys might use more fuel.

Why do yachts use so much fuel?
Fuel is one of many annual running costs of a yacht. Not only does the yacht need fuel for cruising; the generators require it to keep the vessel running while at anchor and underway. As well as this, many of the water sports toys require it too.
Some yachts cross the Atlantic Ocean twice a year between the Mediterranean and Caribbean while others embark on world cruises. That equates to a lot of fuel.
So How Much Do They Really Consume?. According to the Yachting Pages, the longest Superyacht in the world, 180m M/Y Azzam, holds 1,000,000 litres of fuel. To put it into perspective, that is the equivalent of filling a regular hatchback car 23,800 times. Or, six Boeing 747 commercial airliners.
How much gas do yachts use?
On average, smaller pleasure yachts with fuel capacities ranging from 200 to 1,000 gallons tend to be more fuel-efficient. They often feature modern technologies and hull designs optimized for reduced resistance and better fuel economy. As a rough estimate, these yachts can consume around 20 to 50 gallons of fuel per hour at cruising speed. Larger luxury yachts, such as superyachts and mega yachts with fuel capacities of 10,000 to 50,000 gallons, may have higher fuel consumption rates, averaging around 100 to 500 gallons per hour at cruising speed.

Are yachts expensive to run?
Let’s walk through a sample yacht and the yearly running costs with full transparency of a 10-million-dollar yacht. Your major costs will be yacht crew, dockage, fuel, and maintenance. Please understand everything is variable based on those decisions plus the age of your yacht.
Owners can expect to spend about 10-15% of the purchase price annually on operating and maintaining a yacht. That’s $1-1.5 million a year for a $10 million yacht. The bigger the boat, the more crew and salaries you need. There are also other crew costs, like medical and liability insurance, training, and uniforms.
When you are not exploring the world or sunning on the deck in St. Barts, the yacht needs a place to dock. Dockage costs vary depending on how big the boat is and how desirable the marina is. You can lease a dock monthly or purchase a dock.
Like most things, yachts get wear and tear — they require regular maintenance and repairs. Routine maintenance can cost roughly 2% of the boat value after the yacht’s first year, and around 7.5% of the boat’s value when the yacht is 10 years old. That is not including surveys and refits.
How much does it cost to fill up a 100 foot yacht?
The average price for a gallon (3.9 liters) of fuel for yachts is around $3.2-$3.7 in the U.S., but it also depends on where they dock. Even with that price for fuel only, it would take over $700,000 to fill it up.
Russian billionaire Alisher Usmanov’s yacht, Dilbar, is considered to be the largest motor yacht in the world. So, if you were wondering how much it costs to fuel it up, you can certainly buy a smaller yacht for that price, or several hypercars.
Yachts are the epitome of richness, and most of the billionaires own at least one. It’s their way of having fun without worrying about the paparazzi, running into other people, and simply being able to relax. Most of them arrive on helicopters, as privacy is necessary.
Coming in with a length of 156 meters (511.8 feet), Alisher Usmanov’s yacht, Dilbar is a behemoth on water, offering enough room for the passengers to enjoy just about any type of activity they might think of.
Can you live on a 40 foot yacht?
Yes, it is possible to live on a 40-foot yacht. While the available space may be more limited compared to larger yachts, a 40-foot yacht can still provide comfortable accommodations for living.
The layout and design of the yacht, as well as its storage capacity, will play a significant role in determining its liveability. Efficient use of space, clever storage solutions, and multifunctional areas can maximise the available room.
It may require some downsizing and minimalism, but with careful planning and organisation, a 40-foot yacht can offer a cosy and fulfilling living experience on the water and some clients of ours live on much smaller yachts.
What is the average mpg for a yacht?
You’re now on the right track to finding which fuel you want to put in your boat, but you may still have a few questions about fuel consumption. This may play a big factor in what size boat you choose and what size motor you choose to put on your boat. These are numbers only your boat manufacturer can give you based on their recorded performance bulletins. You’re not going to see mpg numbers out of your boat like you would on a small hybrid car. However, newer boats with four-stroke engines offer very reasonable mpg results when running at cruising speeds. For example, the Sportsman Open 252 is an average size boat and with a 300HP Yamaha XCA. You will get roughly 4mpg while cruising at speeds around 25mph. Boats, such as smaller skiffs running 30HP motors, will get much higher MPG ratings due to the fact that they’re lighter with less drag. So, if you’re looking at an average size vessel you can expect around 3-5mpg while cruising. This should help you factor in your potential fuel costs, especially if you know roughly where you’ll be taking your boat.
Lastly, you’ll be looking at fuel costs. Fuel at marinas costs much more than fuel at a gas station. If you’re trailering your boat, you should be able to fuel your boat at a gas station for a lower price per gallon than those dry docking or leaving them in a boat slip. You should, however, still get fuel from larger companies because they often include additives in their fuel that help corrosion. (Yamaha, 2017). Additionally, they cycle their fuel much faster so it’s not settling and collecting bad by-products from inside the tanks.
Needless to say, fuel is a major consideration when purchasing a boat. It shouldn’t scare you though, just follow the directions of your manufacture and try not to let it sit in the fuel tank too long. Outside of this, you’re good to go! Just go get on the water and have some fun with your family and friends.
How far can a 100 ft yacht travel?
How Far Can Different Yachts TravelYacht TypeTypical Size RangeApproximate Travel RangeSmall Motor Yacht30-50 feet200-400 nautical milesMid-Size Motor Yacht50-80 feet500-1000 nautical milesSuperyacht80-200+ feet1000- 3000+ nautical milesExpedition/Explorer Yacht70-250+ feet3000-6000+ nautical miles.
The following factors can affect how far a yacht can travel:
- Fuel capacity and efficiency
- Engine type and power
- Yacht size and weight
- Weather Conditions
Fuel Capacity and Efficiency. The bigger the fuel tank, the farther you can go on a single fill-up. But, just like cars, some yachts are more fuel-efficient than others. A well-designed, well-maintained yacht will squeeze more miles out of each gallon of fuel, even if it has a smaller fuel tank than another, less efficient vessel. For example, when you are looking to rent a yacht in Dubai, it is important to consider fuel efficiency, especially if you are planning a long voyage.
How far can a yacht travel on a tank of gas?
The general rule is the bigger the vessel, the larger the fuel tank. For instance, a 75-foot motorized vessel that can carry 11,000 litres of fuel can travel about 1500 nautical miles, depending on conditions, whereas a 35-45 foot motorized yacht with a 100-litre tank can travel about 400 nautical miles.
However, a larger fuel tank doesn’t necessarily mean you’ll get that much further, since a larger boat would typically weigh more, have a larger crew, have more items contained inside and have more equipment—just to name a few variables.
Follow These Steps to Determine How Far Your Yacht Will be Able to Travel on A Single Tank of Fuel:
What is the fuel range of a yacht?
How far can a yacht travel when it must rely on its fuel tank? As a general rule, the larger the motor yacht, the larger the fuel tank, and the more impressive the range. For example, a 35-foot (10.5-metre) motor yacht with a 100-litre tank can cover about 400 nautical miles. A 75-foot (23-metre) vessel that can accommodate an 11,000-litre tank, on the other hand, will usually reach 1,500 nautical miles. The most accurate way to determine a yacht’s performance and general seaworthiness is a series of tests called “Sea Trials”. These trials assess a vessel’s speed, maneuverability, equipment, and safety features.
Yacht Size and Hull Shape. Irrespective of the theoretical range, how far a yacht can travel also depends on the size and shape of its hull, as not all vessels are designed to withstand the same cruising conditions.
When the height of a wave reaches a certain percentage of a boat’s length (which depends on various elements, such as the type of hull), the vessel is at risk of being knocked down or rolled. In other words, size matters. Smaller yachts, for instance, cannot sustain waves higher than 4 feet and may be best suited for protected harbors, intercoastal waterways and day trips.

How long does gas last in a yacht?
How Long Will Fuel Last in a Boat? Gasoline less than a couple of months old is generally going to be okay, but if you’re storing your boat longer than that, there are ways to extend the fuel’s viability. Fuel stabilizer helps slow down the oxidation process and break down water in the fuel.
📹 How to Find Most Efficient Cruising Speed
If you run a powerboat, you probably want to minimize the fuel bills. One of the best ways to do so is to run your boat at its most …
I don’t even have a boat and I watch as many of the websites as I can to learn as much as I can. I just recently sub’d, like this morning, to BAB. The technical aspects and opinions are about the best of I have come across. I am 62 and medically retired on a fixed income. With that being said, I still am looking to get an older Wellcraft 248 Offshore to refit and use for fishing with my younger brother. I am of the opinion after having used a rental with a four stroke 200 Yamaha that I will be re-powering with a 4S 250 Yamaha on a bracket. It my never come to fruition, but I can research and plan my boat based on the information available. I was aware of the general idiosyncrasies of a boat’s makeup, but I never had cause to get really in-depth into it like my sister and BIL who are avid boaters with a 26′ Formula and a 32′ Tempest. Now more recently taking notes in my dedicated notebook. Thanks for sharing your knowledge with the tadpoles. BTW, the Offshore will be used primarily in fresh water, in Lake George New York.
Love the article! I have a 1994 Searay 34 foot express cruiser I cruise about 20 kn at 3000 RPM roughly 16 gallons an hour which prior to this article I thought it was really bad but she’s a very large boat 11 1/2 foot beam I’m actually quite content with my numbers now thank you for the article I’m going to make a article about this thank you guys
Excellent article – lots of great info. I’ve been aware of the benefits of trimming up for years but did not realize it could be THAT dramatic. Unfortunately the gauge package on my 2004 Scout Dorado 175 doesn’t report fuel burn and the fuel gauge is incredibly crude so I’m going to have to install some kind of aftermarket fuel burn meter. (Hey, how bout that for a future Tech Tues!). What I did figure out a couple years ago by topping off the tank, taking a two hour run, one heading for half, then reverse heading home, then topping off again and doing some math was that a slow plane of about 22 mph constant, just me, and that full 30 gal tank, it worked out to just 2 gal/HR out of the Yamaha 90 4-stroke. That really impressed me (cuz I’m a cheap SOB… 😎). I’d say tho my normal cruise is closer to 30 mph (WOT gets me 40…) so Im looking forward to recalculating. I just wanted to see how little fuel I could burn that first run.
25′-6″ Cobia CC with twin Yamaha F115’s – Best economy is 28-30 MPH getting around 2.7 to 3 MPG depending on load and sea state. WOT is 40-42 MPH I didn’t know when I bought it (used), but the props were not matched correctly. They were both the same size (according to the casting stamps) but I could never reach full RPM on my port engine. It was always 2-300 lower than the starbd. Took it to a mechanic and he diagnosed a high pressure fuel leak inside the VST and also that the cupping of one prop was different than the other. After fixing the fuel leak I lake tested and was about 150 rpm lower then. I found a pair of matched props 13×17 – 3 blade, put them on and bam, back up to 6K on each engine now. I keep the originals as emergency spares now, and can fix my own VST fuel pump issues 🙂 PS – Eric aka UncleBob at Gaugesaver is awesome, they redid all my gauges three years ago and turned out fantastic! I bought some of the rubber covers and they still look good. We are planning a #FPTower trip in May sometime looking for mahi and maybe a stay out there too!
I’ve never measured my fuel consumption, but determined my optimal cruising speed by listening for when the motor sounds to be freely running (doesnt sound like it’s under much of a load). Plenty of smooth water and distance to mess with speed and trim on the Missouri river. Around 35mph. Bayliner 212 cuddy with a 5.0l.
The opposite of this trick can also be used if you know you’re going to be facing rough weather. For instance if I know I’m going to be going out almost a full day and burn half a tank of fuel I fill her up to the brim in the morning and add some extra weight as well. A heavy boat will consume more fuel but is also a lot more stable in rough weather. Basically the experienced skipper will use the weight of the boat to his advantage under varying conditions, sometimes light and sometimes heavy. And it also depends on the boat of course, my boat has the fuel and water tanks in the center console so it’s central weight which helps calm the boat down.
150 opti fishing with a 20ft sunbird we fish 6 hours from idling to fast move to different spots we burn about 1/2 mercury 5 gallon tank. It gives my sons 25hp mercury a run for its money on fuel economy fishing wide-open cruising it will get hungry but not that bad. AMAZING.. i GUTTED that boat when I got it redid all the stringers and foam its so lite my little wife can push it around the shop we keep the belly tank 1/2 full for ballast for fear of being tipped over.
I was exercising a customer’s 37 intrepid and it would top out around 65mph with triple 300’s and then we filled up the huge live well and it lost 5mph off it’s top speed lol. We also had another customer that was really picky about his speed on his 39’ nor tech with quad 400’s, even though it smokes anything it comes across he still never wants to fill it with fresh water and made sure his outriggers were carbon fiber. He ordered a 452 super fish with quint 450’s but he deleted the generator, sea keeper, and bow thruster options just to save weight. Basically he deleted the re-sale value as well.
Interesting live data and these are methods everyone can use to fairly accurately determine their own fuel consumption. Thanks well explained! The newer mercs have a type of fuel saving programmed into the ecm. After staying at the same Rev range for more than 2 seconds the fuel mix becomes step for step reduced and the igniting point advanced up to the point of knocking, saving up to 30% fuel! ARO advanced range optimisation. Enjoy saving fuel for more boating
2016 Key West 210 Bar Reef with the 250 Yamaha SHO. First off, I never “cruise” looking for best fuel economy. I know my WOT fuel consumption is around 25 GPH at 65 MPH (6,200 RPM). I usually “cruise” around 4,500 RPM at 45ish MPH. No Idea what the fuel consumption is at that speed. Might check it this weekend.
Perfect timing for this article. I’ve been restoring a 2003 Proline 22 Bay with a 2004 Yamaha SX200TXRC and sending the Yamaha gauges to Gauge Saver is on my list. I am just now starting to dial in cruise speed and prop. I don’t believe the Yamaha gauges provide fuel burn numbers. Cruise is somewhere in high 20s to low 30s mph with the stock prop. She runs 35 mph at 3500 rpm. Haven’t had the chance to run her up to WOT yet. Thanks for the article, it will be very helpful in the coming weeks. #gaugesaver
My 18footer is very broad and shallow in draft with a 115 ficht 2 stroke. Having hooked up an entire Minn Kota system with an old 105 trolling motor in the bow I simply use the the gas engine to power the batteries from time to time to keep them topped off. I have been looking at jack plates for any next real boats as discussed here but power to weight ratio on an engine in addition to durability and simplicity really matter. Not a fan of the Engineering that is a 4 stroke motor at all therefore. Most go with diesels if fuel economy is the goal anyways. Big fan of the old Detroit Diesel 2 stroke as such. Having said that the purpose as I see it with gasoline motors is the same as for a car namely running all the accessories on a boat which are many now. A/C, heating, electrical, a gyro stabilizer you name it a gasoline outboard engine is a very valuable property of any type or condition.
135 mercury verado on 20 ft. Mako. Doing 37 mph top end and 30 is my sweet spot, the fuel is about 1.7 gph. Not bad but still not the best. Still working it out. Thanks for the added information. I will definitely be using it. As for the GaugeSaver they are highly recommended from me. Saved me about $500.00 over buying new ones. Had a pair done by them and did a great job considering the shape they were in. Keep up the good work guys. Look forward to seeing your articles each week Arron. Stay safe! Have a great week.
Like your car; stats show that in cities; stop and start repetitions use 33% of a vehicles fuel. In Europe where gasoline prices are extreme comparatively speaking, the “Round About” intersections employed seriously reduce fuel consumption. Jack Rabbit take offs in boats as well as cars use lots more fuel. Tire pressure too. The boat configuration hull type, the prop type according to purpose and a well tuned and maintained engine, reduce frowns at the gas pump. Getting your boat “Up On Plane” reduces drag, but with an appropriate Hull to Power combination can be done in a gas conserving practical way. Boating is Happy Time, whether we are flying down the lake or trolling for our favorite fish. This demands dependable and reliable and cost efficient. But in general, poor gas efficiency is often a maintenance issue. The Number one Priority, was and always will be; Safety. At times; Other people’s Lives are in your hands.
I Was looking online for fuel consumption for my new (to me) motor and I found a guy who had almost the same motor who had plotted his fuel consumption vs. rpm. Great resource. But the funny thing was that his boat must have been really slow or lame, because this thing went from like 12 mph to 30 mph between 2500 and 3000 rpm. That thing must be hard to plane. I hope mine isn’t that weak. But his best fuel mileage was around his lowest planing speed … 3000 rpm, give or take, but it was similar for up to around 4k.
Sportsman 19ft Island reef with a mercury 115 four stroke set high running a solas titan Hr 4 blade 19 pitch. On a light load she cruses at 26mph @ 4000 rpm burning 4.2gph. WOT = 45mph @ 6200 burning too much fuel for me to look at 🤦🏽♂️ perusal this post I was hoping for a magical solution for fuel consumption as petrol here in Hong Kong is Us$ 8.7 per gallon 🤦🏽♂️😭, but apparently I’m already covering most points to help with my fuel consumption. Still a comprehensive rundown on fuel efficiency.
I have a 260 I/O Merc in my 248 sportsman. Best investment was a gps enabled Floscan fuel totalizer. now i can trim it out to get my best fuel burn. She will only hit around 28mph full throttle and we cruise at 2900-300rpm at 20-22mph burning around 11gpm. The motor rpm tops out at only around 3800rpm though. Should I re-prop to get a higher rpm?
I have an older boat. 23 foot 1999 Kencraft 220 with a 225 HP Mercury 2 stroke outboard. I wish I had a flow meter to see. But I am guessing at 4000RPM I am doing about 10.5 GPH cruising at 27MPH. The boat tops out at 45 MPH @ 5800RPM, which is nuts. My boat is in mint condition for being 21 years old. Hope you can help me out!
My 2006 optimax I just bought I inslalled them borh the same way. but when I star them up the left one works just perfect, but the other one rpm goes up to 1800 and wont go down. I change the Throttle Position sensor and it keeps doing the same. before I bought them I tested them and they were great don’t know what’s going on with it.
The overall cost of having 2 or 3 engines is expensive. Even if you are burning 16 GPH per engine, that’s 32 gallons per hour for two engines or 48 gallons with 3. WOT, 3 engines burning 87+ gallons per hour. At $2.50 a gallon that’s $217.50 per our at WOT. Even at half this rate, ($108.75) those fish get expensive!
Unfortunately I’m currently running an underpowered outboard on my boat using a yamaha 25 on an old 60’s or 70’s 16′ boat. To save weight ive been using a jerry can instead of the built in tank, only bringing a 4L jug of water+ couple snacks, minimum safety gear, smaller anchor with less chain. Can’t wait to repower
I have a 25′ Sport cat with dual 150 mercury two strokes and at 3200 rpms trimmed out it does about 30 mph but at that speed I burn 50 gallons of fuel in 60 miles so she’s a gas hog and I need to slow down probably lol. I have to note that I always keep both 76 gallon fuel tanks as full as possible so I’m carrying some weight.
My economical cruise is 3000-3500 rpm, 35-50 km/h, at this speed fuel usage per km remains the same and I average around 1.3km per litre. Boat is a 24 foot half cabin, 23 degree deadrise at the transom with a new Mercruiser 6.2 300hp pushing a bravo 2 leg, 2.2:1, three blade 23 pitch x 17 inch aluminum prop. Boat weighs about 2700 kg (6000 lbs) on the water. I think this translates to 3.1 mpg anywhere from 22 to 31 mph. Fuel is typically $1.50 litre but with the CV19 restrictions it has dropped to 90 cents. Problem is, in my state it is illegal to go boating/fishing/hunting etc….Victoria, Australia 🍺🍺🇦🇺🇦🇺

I have a Larson 16 footer I installed a switch board 6 gangs with usb and charging port for phone charger before the gas tank gage was working now it does’t work I traced the withers from the tank to the gage to the battery and they are fine I don’t know if it’s the sending unit or the gage can you help? Thank you.
Question: If you can get your boat on plane faster, wouldn’t that also save gas due to the decreased drag (if I understand planing correctly). Wondering if investing in a wider hydrofoil on my older yamaha 200 2-smoker in my ’95 Century 2200 is worth the $50-75 investment? They SE Sport 300 Hydrofoil on amazon has a lot of good reviews and it’s what I’m considering installing. Thoughts? #GaugeSaver
I`m looking at a boat with a 2003 Johson 150 2 stroke with 400 hours. The owner said that if you give it some gas while in reverse the prop wants to rise out of the water. Is this an easy cheap fix or something major. I’ve read that it could be a tilt trim spring or clutch dog pin. Any advice? #guagesaver
Where in the hell does this guy get his information? “Most boats have a cruising speed around 30-40 mph” Bullshit! Planning boats have a cruising speed based SOLELY by the top speed of the boat. So, boats with the same top speed will have roughly the same cruising speed, but in no way do “most” boats have the same cruising speed as you state in the article. For example: bass boats designed to run 80+ mph will have cruising speeds above the top speed of your so-called “most” category. Since I live in florida, there isn’t much on the water, either salt or fresh, that isn’t designed for 70mph. The cruising speed, by definition, is the speed at which the boat can travel the farthest on one tank of fuel. So, X gallons per hour @ Y speed times total gallons available equals distance to travel. Most manufacturers do these charts at roughly every 1000 rpm, then narrow the cruise by 500 rpm. The one thing in common is that planning boats in general, use that word “most” if you want, will have a cruising speed of about 3/4 throttle.
