Fascinating, very high tech, they look like they're flying like a glider.

Foiling has made the sport pretty crazy. I've been racing One Design, PHRF and IRC keelboat fleets for a couple decades now but still haven't had a chance to cut my teeth on a foiling boat yet. I'd love to "fly" though.

I would think you'd add an icebreaker in there.

I remember in Norway they had small hydrofoil ferries for public transportation in the Oslo fjord in the '60s. Great fun for me as kid.
