Yeah, I've seen them, but they weigh next to nothing, and only sail in relatively flat seas.

Wild Oats has them, and she goes pretty fast, and we'll probably see them appear on more boats to improve righting moment... but it's a massive step to actually get a 100ft+ cruiser/racer's hull out of the water.

Current cup boats are foiling but with a curved foil rather than the T foil shown in that vid.

Steve
I think the current boats are also 50' catamarans as well? The switch to a 75' monohull has me interested in where this is going, it has to be harder to make a large monohull foil than a catamaran? And the monohull of that length has future scope to become a more of a cruiser than a racing cat due to the additional interior space.

Foiling super yachts?

Would take some pretty amazing advances in technology, and the foils would need to be huge.

Even on IMOCA's and VOR's (c.60ft, and very light/fast), the foils don't lift the boat out of the water.

The Americas Cup foiling monhull's have an open hull design. They are basically just fk off great big dinghys

A big interior space isn't needed on an Amercia's cup boat, it is just dead weight. Even the VOR65s are hardly palatial and the crew spends weeks at a time on those.

A common misconception, 3000 gross tonnage is not a measure of weight but of internal volume. She will weigh considerably less than that.

But fantastic engineering nonetheless.

Quick googling suggests a draft of less than 4m - surprisingly little, is this right Speculatore? If so those batteries must be heavy lumps.
Yes, of course, my error.

Says 7m (of which 4m is keel) in this article...

https://beam.land/yachts/black-pearl-the-story-beh...

That's pretty shallow for something so big... a 100ft Swan has a draft of c.6m.
The hull is 4mtrs and with the fixed keel the overall 'Depth' is close to 7meters. The Net tonnage is around 860 tonnes. The top 3 meters of the masts fold down so we can get in to San Francisco....

Not too bad then. Most cruise ships only draw 8m so it shouldn’t have too much trouble getting around the popular spots.

Will she fit through the canal? I can’t remember if the Bridge of the Americas higher than the Golden Gate.

Golden gate is apparently 220ft, BotA is 201.

A few more photographs of the yacht 'playing' just off Gibraltar as we were waiting for the berth to become clear.

I saw Maltese Falcon absolutely creaming along downwind under full sail in a Bora in Croatia, never forget it, bloody amazing.

Having seen it working I really like the Dynarig, not quite sure about the Pearls black sails yet although they are growing on me. I love the whole concept of the yacht though, it's the future for sure.
If you watch the movie (Black Pearl) there is a great line that says.. "I have seen a yacht with black sails called the Black Pearl.. Crewed by the damned with a Captain so evil the gates of Hell spat him out"......

Being nosy and a bit thick,

do the sails furl in from the center to the mast?

If so I assume that there is no real reefing and you just alter the amount of sails spread since it seems that partial spread sails would not be that good an idea.

She is beautiful and a lovely development of the rig. Even if seeing masts without head sails is playing with my brain

Dumb question, apologies, but is she fully ballasted and floating on her lines there?
Is the reversed part of the bow meant to be underwater or is that roughly the designed waterline as shown in the photos?

So, you have a good skipper then....

Brings it into perspective...that red spot in photo 4 is 9 people standing on the foredeck.

I expect it will be in boom furling.

Aesthetically, to me it looks like a motor yacht with 3 masts... not classically beautiful like a J or a Wally Cento, but surprisingly looks good with the sails up and some angle.

In to the main mast. Correct regarding the reefing. Each sail is either fully stowed or fully spread. The 15 sails are controlled separately dependent on the amount of wind.

I thought the name was a bit cheesy, but that enormous logo on the sail is just grotesque.

(the yacht's amazing, I'm not slighting the engineering)

Utterly ignorant when it comes to boats, my experience goes as far as the ferry to Holland however on the Black Pearl pictured... the line of windows along the water line, I assume that being equipped with sails means it'll be moving along at fairly jaunty angles more often than not and thus, said windows will be under water? On which note, are the sails used for making progress with the owners / guests aboard... given these things seem to be utter luxury, I can imagine everything being a 30deg a bit of a chore or have I completely missed the point here!

Windows under water is relatively common on a number of less extravagant sailing vessels.

Here is a tame pic

Cheers, yes though I think the aspect my head can't get round is the sailing ship / tilt / water / sipping G&T as you get along concept... not sure on the layout etc but I have images of waking up, throwing open the curtains and getting an underwater view which strikes me as a bit daunting! But again, not sure on the usage... ie does it go under sail when the owners / guests are on board for "novelty value" as it were and thus, it was part of the design brief or would sails / tilting / water past the windows and guest on board never been seen together?

Probably not making my thoughts very clear, but to be the sailing ship / jaunty angles aspect of the boast seems to contradict the ethos of such a thing, ie lavish luxury. I guess on a similar vein, the most traditional set ups... ie the huge things that float around the Med, they must be fabulous on a calm day but I assume that when underway from port to port over greater distances, thus more than likely to face adverse weather and thus get a bit lively... I assume most owners / guests wouldn't be on board?
