How does an electric ferry 'fly' above the water?

TechCrunch (Oct 3) covered Vessev's electric passenger ferry, which looks like it's flying: at speed, hydrofoil wings lift the hull clear out of the water, leaving only the slim foils touching it.

WHY this is the key to electric boats: water is roughly 800 times denser than air, so hull drag is what murders an electric boat's range — foiling removes the hull from the equation and range jumps. HOW it matters to you: it's the same physics as America's Cup sailboats and electric surf foils, finally scaled to transit.

Watch next: docking precision, floating debris, and port regulations are now the hard problems — the motors were never the bottleneck.
