Solar “e-Yacht” — Environmental Boating?

I would call the photo here deceptive.  The manufacturer of the “Greenline 48 Fly,” as it’s called, represent their product as “environmental boating.  Yet it has two diesel engines that deliver a combined 440 horsepower.  In full sun, that solar array will deliver about 0.5 horsepower, so about 0.1% of what’s required.
