I love the idea of a calibrated tank so you don't NEED flow meters but sure seems like it would have been a LOT easier to flow meters to do all the calculations and then you always have the calibrated tanks as a fall back. When cruising I'm going to want to see all the data integrated onto my screen. Then if something is amiss, I'll go check the physical tank.
Great boat for anybody that just wants to go the marina and cruise into the horizon without having to depend on somebody else for boat handling. This boat can go from USVI to Fort Lauderdale non stop! This beats the crap out of the Grand Banks 42 I used to cruise on.
Great video and I do feel like a moron. I could have come up with this myself to measure the fuel usage of my Ford Lehmans 27-15E's. However I didn't, so after seeing this video..............I will do the same test. Have been wondering for a long time what my fuel usage is and it has nothing to do with cost, it has everything to do with 'where can I go'. Thanks.
GS, a full-displacement hull (one that doesn't plane on top of the water) has a theoretical speed limit, called the hull speed, that can only be slightly exceeded. Installing larger engines will not give significantly higher speeds, but will only result in more fuel burn. For more information, see: en.wikipedia.org/wiki/Hull_speed
Brilliant though all these figures may be I have an 11 year old Swift Trawler 34 with a Cummins QSB 5.9 litre Diesel engine (425hp) as standard. Being the “spotter” I am I’m pretty anal on fuel figures and the like. 407 hours run from new (like my cars I buy, two owners just run in) and she runs 9 litres per hour at 7 knots and 55 litres per hour at 15 knots. In UK terms that’s 3.5 miles per UK gallon at displacement cruise and overall running I see a shade under 2 miles per UK gallon on average. I love the look of this 41 and yes the build quality is on another level (or two) above my Beneteau, but I had been expecting better fuel consumption figures. Perhaps you could publish litres per hour at the max displacement cruise?
Those are impressive consumption numbers ... I don't know why anyone looking for a versatile small trawler would look to buy anything else but this N41
I think Nordhavn's philosophy is KISS (keep it simple silly). Flow meters can break down. Day tanks with calibrated markings showing quantity are ultra reliable.
"Should of (sic) put a day tank like the 63." It has one. As he clearly stated in the video, they did this test to confirm the accuracy of the day tank, referred to in the video as the supply reservoir.
You add about 50-60% to the cost. It's the labor cost that kills you. I looked into it in both China and Turkey. China is cheaper than Turkey, but not by much.
Red diesel in my part of the country is "off highway fuel " is cheaper because it avoids extra taxes for road repairs. You can use it in heavy equipment, and boats just not in your 18 wheeler. When you get pulled over by Johnny law they can dip test your trucks tank looking for even trace amounts of red die to see if you paid taxes, not to mention the fuel tax sticker that must be on your trucks tank.
the 41 looks like a fantastic boat, can't wait to see more about the 51
This 41 reminds me of the 35 they used to make. I like it! Good job Nordhavn
Looks like you guys hit another homerun. Very very nice.. if I was able to swim in the nordhavn pool I think my choice would be the cp59 to start

Very nice, what would the cruise distance be, like to the islands?

Are paravanes an option for stabilization on this model?
so what's up with the 51?
why didn't you put the tank on a weight scale so as to be as accurate as possible?

So what is the combined resulting fuel consumption in gallons per hour at six, seven and eight knots?
Is there a way to get more engine options during the build to get to higher speeds?
N41 hull's shape is optimized for certain cruising speed. Like most other nordhavns it's about range and efficiency, not speed.

@@seikibrian8641 good insight Thanks!

This is probably a really stupid question. Why don’t you install digital fuel flow meters ? So simple

Should of put a day tank like the 63.

Looks like a tough job, but someone's got to do it😅
Don't answer if you don't want to... but how much would a N41 cost if it were made in an American Shipyard instead of China?
This boat is made in Turkey.
@@chrisbynum4940 ahhh yes... true. I was thinking of the rest.

Is it noisier than the single John Deere?
Probably not. In the walkthrough video Jim said the noise level of the N41 was as low as some of the bigger Nordhavns.
They had the hatch open to the engine room. That is what you are hearing.
What’s the point of this video? What’’s the fuel burn? Is there a chart posted somewhere?
Found the chart on the Nordhavn web site. Thanks Jim!
Red diesel?? 🤔
