Clickbait warning... The video that appeared at the top of the page (followed by a bunch of blank space, presumably blocked ads) featuring a superyacht is NOT about the yacht in the title, although it does also have solar panels.
There is almost no real information here, not even the name of the engineer. The pictures are credited to "true north yachts", and searching for this reveals a patreon that talks a lot about sovereignty and also youtube growth hacking. There's a patreon (called truenortharchive, not sure what it's archiving) and there doesn't appear to be any substantial information about this actual boat.
There are a couple of shots of the plywood construction, but no hard information. At one point he shows the camera the power control interface, and at another he shows the outboard motor, both of which seem to be off-the-shelf at https://www.epropulsion.com/
With wind? Sure. With solar PV? Only recently. You're still going to need a watermaker to make fresh water, and consumables for it, along with food, but with enough solar, it is very compelling when you might have challenges sourcing diesel (whether financially or logistically). Scratches the self sufficiency itch to an extent, sailing solarpunk style.

It's pretty crazy that the article does not state how many theoretical watts the yacht has. It looks like maybe 4,000 watts from the photo of the panels.
The video that the person made has the stats. (see further up, its only about 8 minutes)
From memory its a 5.4kw array with 8kw motor. At 400w it can (on a calm inland sea) cruise at around 3 knots. Top speed of ~9 knots.
Its made from plywood so its super light. he wants to take it across the atlantic, which I think is brave given that its not got any compartments(that I could see in the video), so any breech means it'll sink in minutes.
Brave or stupid ?
What I could get is that he is a young fool looking for "freedom" where there is none to be found.
The boat isn't even interesting anyway, it's a bit dumb to spend that much money on an inadequate power solution when a cheap refurbished ICE would have been just fine.

Clickbait article, that's not worth anyone's time.
All available information seems to be in this youtube video: https://www.youtube.com/watch?v=bX5EraBZ0As

By my estimate whole setup would cost less than a single marine diesel engine.
