So I am doing some math, does this sound right?

The new Sea Ray L650 Yacht is amazing, but my question is about the fuel and fuel consumption.

The fuel tanks total 1,030 gallons, and a nautical mile range of around 273 miles (439.35 kilometers) on a full tank. It runs on 2 x 1150-hp CAT C18 ACERT diesel motors.

So, if you figure it is a 1,000 mile trip one way (roughly) from San Diego to Cabo San Lucas, you are looking at filling the tanks 4x EACH WAY, so 8x total round trip. That's not including cruising around Cabo on your vacation.

Diesel being roughly $3.50 a gallon right now, so that means it cost $3,605 each time you fill the tank. If you have to fill the tank 8 times, that means a round trip cost in fuel alone for this vessel is $28,840

No, I do not own the L650 but I am a bit surprised the nautical mile range is only 273 miles. You'd think a Vessel of this scale would be able to cruise 500-600 miles easily on a tank of fuel.

That is at a cruising speed of 26.5 mph spinning a little over 2000 rpm's. I'm sure it would do better cruising at 10-13 mph.

So the boat is prob 80,000-90,000 lbs, has twin 1100+ hp engines, and you are surprised it gets about .3 of a mile to a gallon cruising? My boat is tiny compared to this, and I am happy to get 1 mpg if I am lucky. Poker runs I use 2 gallons to go 1 mile, so .5 mpg in a 10k lb boat.

I always equated the new retail price of the boat directly = fuel consumption

Also note the driving distance is 1032 miles but as the crow flies it is only 800+/-......Most SeaRay owners don't go on 2000 mile trips either

Yea... a full tank at 273 miles would last you a month or so at Lake of the Ozarks or similar to other inland lakes.

Maybe it is only designed for lake use.... Lol

A range of 273 miles is seriously low for a big cruiser. That would probably close to double at 12 knots and most people who do long voyages cruise at lower speeds. Once onboard with all the comforts, there's no need to get anywhere quickly, enjoy the journey!

A friend of mine cruised the east coast of Australia in a Riviera 58 some years ago. He set a goal to get from Melbourne to The Whitsunday islands, probably 2-2500 miles. He cruised up at around 21 knots and it cost him 16k (Aussie dollars) stopping only for fuel. His return journey, cost him a little bit less included lots of sightseeing and stop overs along the way but he cruised at a lesuirely 12 knots.

He enjoyed the first 4-5 hours on the way up the coast at higher speed and the weather held good for the whole trip. He had a time frame when he wanted to reach the Whitsundays so he kept moving. After 5 hours, he really wanted to slow down and relax, although the boat was exceptional, he said the constant slapping of waves and a little bit of pitching became annoying but he stuck to his time frame. He enjoyed the slow trip back a lot more, and so did the wife!

my guess is if you can afford that boat fuel costs just don,t matter.

∆∆∆ have to agree with Mike...if you can order up a $3million dollar Sea Ray and can justify b*tching about fuel - SURPRISE
, you're a Blow Boater!!

Not many boats go far at cruising speed, and that's not setup to be an efficient cruiser like a trawler. Everyone runs like 7-10mph on those long hauls.
