America's Cup chase boats?

Hydrogen-powered hydrofoil 8-passenger Chase Zero boats.

If the motors are drawing 350kw and the fuel cells produce 160kw (according to the image)... I wonder how long the batteries last and how far it can actually go?

(It must be ungodly heavy if it takes 470hp to go 50kts up on it's hydrofoils?)

The video suggested they went 5+ hours @ various speeds and had some fuel left. You and I both know they won't tell enough to look bad. ;)

I guess the range/duration just depends how much hydrogen they can carry.... but it looks like for the fuel cells to keep up with the motors they would have to be running well under 30kts average?

It’s great to see new hydrogen technology get a trial run. As for the eco-friendly part I think it’s a stretch when discussing an all carbon boat chasing a fleet of 36 foot, rigid sail, carbon fiber and epoxy boats. But it’s all fun watching cutting edge tech flying around course.

It says it is 5600KG. Thats 12,320 lbs. But it also says it is 13 Meters long with a 4.5 Meter beam. Is 12K lbs. heavy for a 43+ foot long 15 foot wide boat?

That doesn't really seem too out of line... odd that a boat that big would normally accommodate about 20 passengers versus 8?
