It'll be interesting to see what's at the Annapolis show this year. It's coming up next week.
Keep in mind that the Sea Keeper is of limited help at higher speeds. Now, obviously crossing the Atlantic, they'd go slow.

Then there is PowerPlay, which have a few on the water and some used for sale.

Plenty of choice, you are not limited to the French volume builders or one-offs from great designers. For some of these you could enlarge tankage in a new build if you believed the range insufficient.
I wasn't familiar with the Heliotrope. Interesting.

Isn't the Isara sail only?

I'd heard of Powerplay years ago. I had no idea they were still in business.

Thatís impressive but that means it gets about 9 nmpg. Maybe the extra 0 was a typo though

I'll have to locate the quote with the higher number but regardless it's far off reality.

Yes, sorry about the Isara. I'd always assumed the wires and stick could be readily ditched, but it may not be that easy to get a balanced boat afterwards.

With that being said I have never cruised one so I can’t say for certain how realistic those numbers are. But they are at the very least the advertised numbers which I in no way stand behind.
I can see that or at least believe it with neither wind nor current on totally flat water.
The Europeans are really conscious about fuel, even rich ones.

I looked at many European boats, especially Dutch, ones during visits to the Netherlands in 2009 thru 2011. The style, like the Ellings, appealed to me.

But as I learned more, my issues with the engine room, as well as storage space, became predominant.

Americans work on their cars and boats far more than Europeans, even more so in the 40+ foot market, thus good engine room access is simply not important in Europe. It's more important to minimize that space, to maximize fuel economy and living space.

The only European I know who works on his own boat has a Kadey Krogen.

Another long range power cat that I'd forgotten about is Iliad.

The 70 is at the T-head of my dock right now for the Riverfire event tonight

Nice looking boat. You Pacific Islanders seem to dominate the Power Catamaran market. I noticed they have one 50' available for September 2020, then next is 2021.

Now our big question is what is the largest Catamaran, with beam the limiting factor, we could use for the Great Loop.

Excellent Brian, thank you. Iíll try and add them in if I can find a few data points on consumption.

Isara is sail, not power. But Powerplay has some figures I can add. I thought the Powerplayís were a Schionning design, but his name wasnít mentioned as the designer/architect. The look seems to be very similar though...

IN the1950-1960 era he AYRS in England had members building ans sailing on foils. The latest issue of PBB shows finally the big buck folks have been doing research on foilers.

With modern light weight construction ,foilers become more pratcical.

The next generation of diesels will be more efficient and weigh under 1 lb per HP.

Weather the folks that could afford these boats want to motor across the pond remains to be seen.

Hmm, there looks something wrong with the Powerplay 56 "reviewed" consumption (and thus range, trying to relate back to the original point).
Note I'm still only talking power cats, not monos...

For the Fountaine Pajot My37, MY44, the Cumberland 47, Aquilla 48, Sunreef 70, Horizon 52, Africat 420, all of the consumption figures match to a linear or reasonable polynomial, but the Powerplay 56 is a real outlier.

My suggestion is simply to be wary of their consumption figures, and thus their range (which is published as being 5000+nm at 7kn). It still does have 6500L of diesel, so could cross the Atlantic with some ease!
