What engines do you have?

I'm always puzzled by these requests.
I mean, if you're interested in a 20+ meters planning boat, of all things, do you think it's the fuel consumption that can make it or break it? Seriously?
Besides, it isn't a matter of models, it's essentially just a matter of size and weight.
At a cruising speed anywhere between 20 and 25 kts, all boats of that size will burn around 11 liters per nautical mile, give or take.
The difference between the less and the most efficient comparable boats may be plus/minus 10%, if that.
I'd rather pick the one with the cushions colour that my wife likes better...

it’s a simple, sensible, question, why not just answer it rather than go all judgemental?I'm always puzzled by these requests.

He did.
…. ‘anywhere between 20 and 25 kts, all boats of that size with will burn around 11 liters per nautical mile, give or take’
Probably about right, and if we knew the engines we could find the prop curves and offer a bit of science to back that up.

To be fair, it's hard to answer a question where all the salient information is left out. That boat could have three different engines if a Mark 1 and then there's a Mark 2 and a Mark 3.

No, it isn't.
Aside from the fact that there are several very different models of Pred 68, have you ever seen a fuel burn chart for ANY Sunseeker?
I'm aware of just a handful of boatbuilders who disclose what the OP is asking, and S/skr ain't one of them.
In fact, I've got the fuel burn charts for several MAN engines (which AFAIK were installed, in different versions, in most if not all Pred 68), but even the ENGINE fuel burn chart, in itself, is not enough to answer the OP question - hence my ballpark number.
But I'll read with interest anything more accurate that you might be able to offer.

Here is one for the SQ68

I fully agree with the comment that in the real world fuel burn at cruising speed for large planing yachts is usually in the 10-11 l/nm range, provided the bottom and props are reasonably clean.
Sunseeker does publish fuel burn and range charts, they're just not made widely available to the public. Here is the chart for the Predator 68 from the booklet produced in October 2017.
My guess is that the values are for boats fresh from the factory at half load tested in UK waters. Fully loaded in the Med, and with fin stabilisers, you will not achieve these values. For example my P57 which is fitted with fins is generally about 10% worse than the published values across the board.

Is that for the Mk 3? I think it was around that time that the Mk 2 was discontinued.

I think that the general principle that fuel consumption is only a very small part of the on going financial outlay is true. But if the OP wants the figures to see if his boat is performing as it should....or is planning to charter a boat for a holiday....then it’s certainly valuable knowledge to have

Again though, not enough information given to elicit an accurate reply. There's a minimum of six different engine/boat combinations available. @DAW has provided the data for two of them, but we don't know if that's what the OP is looking for.
And the OP hasn't reappeared here since asking their question.

I'm pretty sure its for the Mk 3 ... the booklet also contains information for the 68 Sport Yacht which was the same boat with a small flybridge.

Happy to stand corrected, though it remains a mistery to me the fact that some builders go to the effort of making booklets with these numbers and then treat them as if they were classified documents!
Did you get that booklet in Mar-A-Lago?
Anyway, it's interesting to see that my guess was right on the money only at the low(ish) P speed of 18 kts, while at 25 kts (which isn't exactly warp speed, particularly for a boat that pretends to be sporty) it goes up to almost 14 l/Nm.

I suppose it’s very much like the car industry....if you announce the economy, people who don’t get those numbers will be upsetHappy to stand corrected, though it remains a mistery to me the fact that some builders go to the effort of making booklets with these numbers and then treat them as if they were classified documents!

Because the OP only has 2 posts to his name, one of which is the current post, he’s a newbie as such and the tone some of the replies came across as unnecessarily arrogant in tone instead of friendly.

Except the OP was gone the minute they posted their question, they didn't wait around to read any replies; good, bad or indifferent.
